Hermine Raises TS Warnings for Cape Cod, Frances Track Questions

4:45 PM
The remnants of Gaston are continuing to dump lots of rain and spawning Tornados in southeast Virginia.

The Frances 5PM Update has the track a bit to the left, placing the risk for the Florida Peninsula up higher. Assuming the track verifies, landfall would occur Saturday. It's too early to pinpoint where exactly it will hit too (and what strength). (GA And the Carolinas aren't out of the woods yet either)

Folks along the entire Florida East coast must watch this system over the next few days. Watch for trends in the models. If they trend westward Palm Beach down to Miami will need to watch, if the tracks hold then central Florida will need to watch more

If they trend right, then a brush will happen and the Carolinas will need to keep watch closer. If the more southerly route happens, it could become a gulf concern as well.

To restate the National Hurricane Center, it is extremely important not to focus the exact track, especially at the long ranges the maps show. The hurricane isn't a point, and Frances is a large system. Forecast errors that far out can be off several hundred miles. Don't use the "point track" as a guide right now.

Stay tuned.
.
Original Update

Tropical Storm Hermine is getting close enough to Southeastern Massachusetts to cause Tropicla Storm Watches along the coast there, including most of Cape Cod and Martha's Vineyard. Expect a nasty overnight there.

The remnants of Gaston are near the North Carolina and Virginia borders right now dumping loads of rain and some minor wind.



The biggest question for most people is about Hurricane Frances. This weekend will be interesting for Florida and the Southeast. It becomes another race for recurvature similar to other storms with this path in the past... The question does it reach Florida before it curves or not?

It is indeed prudent to begin thinking of advanced preperations for the storm on the labor day weekend in Florida and southeast.

Although its still a little too soon to tell where it may wind up. I'd suspect to know somewhat better Wednesday. Models have trended left and right over the last day or two (left would mean more impact for Florida, right would put the Carolinas in the eye) Of course projections that far into the future aren't worth much.

With the latest model runs, it trended back left again. But I suspect it'll change again. Beware the hype with the storm, but keep focused on it during the week if you live along the areas including east coast of Florida, Georgia, and the Carolinas

Looking at some of the latest model runs, it looks like the current NHC forecast track is to the right side and even outside of model consensus. Wonder if they will make a significant move to the left at 5:00 or hold on for another set of runs before doing it?

TPC finally issues a TS warning. This storm is at 50MPH moving north at 22 right straight towards Cape Cod and it doesn't seem to be getting weaker. There should have been a recon flight. Not much warning for marine interests.

Heads up!!!!

Hi Everyone,

To all along the East Coast and inland, PLEASE make your preparations now. I was just at the local Walgreen's, and most of the batteries are gone. Plywood and generators are going fast as well at the Home Depots. I learned my lesson from Charley. Also, they are picking up debris in and around Orlando from Charley which tells me that the city is concerned as well. All those downed trees can be flying projectiles.

Stay safe!

Re: Vortex Message

I brlieve the intensity level is down...89kt flight level should not support 120mph...but we'll see. The sat pics show that Frances is now moving north of west pretty much as predicted.
My question is what the role of the ULL now rotating ove the Southern Bahamas will have on Frances track...It has not moved too much today...If it stays south and west of Frances, it could enhance inensity and help throw the storm back to the west in a hard turn, as some here and some of the model graphics seem to now begin to suggest.
Any way for now, I sense the intensity will fall to CAT II.

Wobble?

Last two frames of floater 1 show what appears to be our first north (actually more like wnw) wobble...wonder if she's thinking about making that turn soon...interestingly her Dvorak's remained at 5.5/5.5 so maybe she isn't strengthening...however, now that the bird has given the recon data...the pressure drop would certainly lead one to believe she's strengthening...Guess we'll know more at 5:00.

NHC Track

I don't know if they'll make a major adjustment to the left, but based on those new model runs + their concern over the GFDL model run, they may move it a little bit back to the left. It has been going back and forth for the last few days, which is normal. Time will tell.

I checked out the UKMET run that was posted (by Phil I think?) and if that verfies than Florida is going to be one big mess. They still haven't finished cleaning up all the debris here, either...and there is plenty of it. It will be a knock-out punch for all three parts of the state -- east coast, west coast, inland and northern gulf coast of Florida.

Imagine all the people coming here for the end of the summer weekend...and how many more people will have to evacuate? Ok, well that's all speculation and I really shouldn't do that, but I can't help it.

I'm beginning to feel like Dorothy in Kansas. The 5pm & 11pm discussions will be very interesting. So will the new tracks. If it does speed up, we may be looking at trouble earlier than we thought.

Or not.

Pressure falls

Yes, the pressure falls would indicate strengthening. Those are obtained with instrumentation on the plane and dropsondes, so I'd say that's much more reliable than the winds they found. As Alex said, maybe they haven't found the strongest winds yet. We'll know more at the 5:00. Hope Stacey Stewart gets to write it!

Stairstepping and outflow

Hey everyone, not willing to even try to project where this sucker is going to go. But it does look like the stairstepping has begun again. Also, earlier today the storm looked slightly 'scrunched' on the right and to the south. Now it seems outflow has resumed and the storms seems to be regaining a more symmetrical look. The dry air that had crept into the circulation also seems to be fairly well absorbed at this time, so I would presume the storm has reached it's weakest point for a while.

Question: Were the forecasters expecting an increase in the forward speed?

Thanks

Re: NHC Track

The NHC has been trending their track between the GFS and UKMET on Frances. I find it interesting that both of those on the last run are in agreement as to the future track. There is no in between ground now for the NHC. Both tracks have it in South FL thru Tampa and into the Panhandle. Worst case scenario for the the state if that happens. If that track comes to fruition, there will be no safe place to go in FL. Not wishcasting here either. I don't want this sucker anywhere near me. I plan on playing golf on Monday and watching the Noles beat the Canes Monday night, so Frances kindly move on down the line!

Also, Gaston could be back over water by 11pm, and if that happens, it will likely go directly to TS because the nrl site has the intensity at 45 mph and 998 mb on the satellite page

Been here about 45 days (lurking at this site since February). We were made nervous by Bonnie.

That's just FSU afraid of the football game Monday night. They hope that if they tweak their model to show a Miami hit, the game will definitely be postponed until a later date. hahaha in all seriousness, I am still finding it hard to bite on a SE FL landfall. I just don't think the ridge is going to be strong enough. I keep hearing people at work draw comparisons to Andrew, but let's face it, the ridge that drove Andrew was the mother of all ridges. This ridging over Frances seems rather pedestrian, and probably won't build far enough west for a direct SE FL hit. Just my thought.

Almost every single one that didn't go through the box didn't hit S. FL. There are VERY FEW exceptions to this.

1) Global models have a real tendency to underforecast ridges.

2) Large storms tend to reinforce ridges.

3) Cork in the stream...Frances won't be influenced as much by the outside synoptic forces as she will flow along with them, and modify them to some extent. Be very wary right now if you live anywhere between Hatteras and Mobile.

I'd like to tell you that you get used to it, but we have never had a month of August like this before, Every single piece of sand has been threatened in about 30 days by one storm or another. I can't recall this ever happening before. You're really in what was a pretty safe area, until this year.

18Z GFDL is a space coast hit and rides the east coast right into my backyard. Never have liked that model.

We are almost at this point:
A) East coast of FL, across the state, into the NE GOM.
B) East coast of FL, rides just inland or just along the coast.
C) A complete recurve, misses FL, Carolina bound.
At 5PM the discussion said this:
THE BAD NEWS FOR THE BAHAMAS AND
FLORIDA PENINSULA IS THAT THERE IS NO SIGNIFICANT MID-LATITUDE TROUGH IN THE CURRENT MODEL FORECASTS THROUGH 5 DAYS THAT COULD SUBSTANTIALLY WEAKEN THIS RIDGE.

Here in Jax Frances is leading the local newscasts top stories. Option C is not being considered here. The word is getting out that it's still 5 days+ away, but get ready, could be a huge problem.

Re: Hermine Raises TS Warnings for Cape Cod, Frances Track Questions

"Hard to see the dark side is isn't it?" Just like yoda says in star wars, its with the model runs with weather.
I waited till the new thread came out to give out my 3 and 5 day forcasts for Frances. Pretty close to track I have this from 3 days back, maybe just a tad slower but still going on to my around 21N and 70W. I have that there in 2 days. Day 3 in se Bahamas around 22.5N and 74.5W. Day 4 25N and 78.5 W and finally Day 5 near 27.5N and 81W. Again from points each way it could be anywhere from 50miles each side on day 3 I forcast and on days 4-5 up to 100miles each side. So everyone from Key Largo N could be affected.
Why is this my forcasted position? Dynamics in the atmosphere with water vapor showings and model runs continue to support this direction. As I mentioned to Hank on here I dont see a strong trough like Floyd encounterd to pull this NNW until it gets past day 5. NHC also notes this now. Now in near term, a general W path with WNW wobbles should continue into tomorrow with the afternoon becoming more WNW around the extreme SW side of the ridge over the Atlantic. By day 3 (Thurs) the question on where it goes will happen. This is due to the ridge placement, strength, and position of the hurricane. With a trough expected to develop over the central U.S and dive southward on days 3-4 the ridge over the atlantic might extend more W into the SE and mid Alantic states. This would cause a path more WNW (as I expect) just SE florida and up or across the state. The trough will continue slowly E into the eastern U.S. down to the lower miss valley and gulf coast by day 5 allowing more NW then N movement. This is by days 5 thru 7 as all can see in GFS model runs. Now currently ahead of Frances there is a upper trough in the bahamas moving w and should weaken but it will also help influence the outflow of Frances and also helping the wnw motion. If the upper trough stays alittle stonger then forcasts and/or slows down, it could during days 2-3, turn Frances more NW and the models will adjust to that. That is possible i should note but not favored.
So for now as posted above that is my placements and threatning the SE coast of florida by late Friday night. Storm could still by day 5 then eigther parrel the coast from WPB up to Daytona or come inland and N of Tampa later day 6, but I wont go out no more then sending it or coming close to WPB for Sat. Will post new forcast on weds. scottsvb

Re: NHC Track

A question: just how big is this storm? Is it a compact storm like Andrew, the size of Charley or Floyd? I'm just wondering because if it stays on the path (which is going to change slightly from day to day) it's on now, wouldn't the worst weather be on the north side of the storm as it passes through the state? Or is that a mute point at this time?

I DEFINITELY don't like the "THE BAD NEWS FOR THE BAHAMAS AND THE FLORIDA PENINSULA" part of the discussion.

People here are taking this storm extremely seriously. As they should.

Speaking of storms, we're getting a nasty one right now. I'm really hoping this cancels football practice.

Re: NHC Track

The ULL at this point is aiding Frances, along with a TUTT behind it, by creating ventilation for the top of the storm. I don't see anything about the ULL that should really impact the track.

Excellent discussion here NOT focusing on any specific points for landfall, contrary to some TV coverage in Orlando. Just rec'd a call that one station is getting viewers in a tizzy about a hit on Cape Canaveral.

Thanks for your reference to Hebert's Box - solid rule of thumb info to know.

As for models, I'm sure we all remember how the models kept trending left of Charley's actual track, but still within "the cone of concern."

Area around P.R. is famous for TUTT effects - remember how Andrew weakened, then strengthened again E. of Bahamas?

The coast of Florida is going to get hit. The only variable is how hard. The west side of Frances could hit it, or the entire thing could.

By Wednesday/Thursday, you'll know if you need to evacuate or not. If you wait until Friday to evacuate, you are going to have to drive to Tennessee to get a motel room.

Re: NHC Track

Colleen, that's a good point and I'd liketo know if the storm will enlarge windfield wise or stay pretty much the same. If it came in on the current forecasted track (theory now) I will be near the NE eyewall (I'm at 28N/80.3W) but if it came in at Ft. Lauderdale will I be safe here. I figure TS winds extend out to 140 miles from the center, so thats about 280 miles total coverageeither side of the center (duh). But will that size increase in 4 - 5 days??? Good Question.

Dont forget the Bahamas!

Hey guys,
i konw a lot of the attention will focus on the possible FL landfall from Frances, or perhaps a more general SE US landfall, and i would expect that to be honest. However, dont forget that Frances will be tracking along the Bahamas before it gets to the US! These islands are small, low, and less able to withstand such a storm. These islands should really be preparing now and getting as geared up as possible, as Frances looks to strengthen, and sweep the majority of the islands too. Its not just a community that could become isolated when Frances tears through, no, rather the whole island(s) - as if they arent isolated enough!

Of course, Frances looks set to hammer at least part of the US SE coast, and it is looking increasingly likely that it will be a FL coast event. More people are here in more concentrated numbers than in the Bahamas, and more potential for damage, devastation, and loss of life!

Hermine also loks set to give parts of Mass a glancing blow, but nothing too serious.

Interestingly too, Gaston has maintained itself as a seperate entity, and looks as if he will move back over the Atlantic waters tonight. Could be something else worth watching too.

Kind regards as always.

things to worry about

no good news today.
frances is intensifying today.. eyewall contraction cycles and less subsidence/vertical shear to fend off.. giving it a nudge back to the way it was when recon found it. ought to be back to cat 4 tomorrow. moving forward a little faster.. expected.
i'm going to keep my landfall window between palm beach and beaufort.. with emphasis between daytona and brunswick.. as a 3/4 on late saturday/early sunday.. still not going to pinpoint.. not until tomorrow afternoon at earliest.
still seeing the dynamics for the stair-step and terminal leftward bend.
other stuff in the basin too.. nowhere near as scary, but there. gaston has maintained an excellent system aloft, and should reintensify to a tropical storm when it moves offshore tonight. the binary interaction i was expecting with what became hermine is in the end happening in a manner.. the lower pressure of hermine has probably helped guide gaston harder to the right than previously forecast. should trace NE as a weak tropical storm (waters too cool to reintensify much).. and pass a little south of nantucket tomorrow night.
hermine shot out ahead of its cdo today and is barreling northward to an AM landfall in eastern new england.. likely a nonconvective or convection-removed depression at the time.. small chance it's a weak tropical storm. my take is nhc didn't need the t.s. warnings after all.
97L (should be 99L.. 97L was gaston) in the eastern atlantic near the cape verde islands.. has a well defined low with some convection. it is probably a tropical depression.. and should be within a couple of days. it's circulation envelope extends westward quite a bit and has another maxima near 33w.
there is a surface disturbance developing in the itcz at 9n/38w.. models havent picked up on it yet.. but this may turn into something too.. hard to say based on it's low latitude the imminent closure of 97L.
globals still hinting at a low development south of the miss. delta over the next couple of days. surface convergence beneath a weak upper shortwave ridge is the setup here. would probably move little at first if it actually develops, then maybe turn nw if a more defined low were to form. still hypothetical and low probability.
the next wave slated to emerge also has globals trying to develop it. september should start out like august ended.
and that's the very long story of the tropics. hell of a lot going on. hope the site can handle all the traffic that's going to be on.

Re: Dont forget the Bahamas!

Not looking so great for Florida right now. I kind of like to focus in the on the Orlando area because I take residence there. I expect the majority of Florida to get a rather nasty taste of Frances due to its large size-I can't rule out hurricane force winds extending outward by 110-120 miles by the time the storm nears the Bahamas. I can feel this one coming on already. Frances looks remarkable on satellite images this evening.

The NHC track looks pretty darn good to me at this point. Barring any MAJOR changes, you can pretty much expect tweaks in the track forecast throughout the next few days. Another scary point-NHC stated in the 5 PM discussion that the intensity forecast could be "conservative".

Good grief...

I still think the hurricane will stay generally west...a little north to that. Not sure about the latitude HankFrank is guessing on..though his expertise is miles above mine. I go on hunches based on what I am seeing, and reading....he goes on sound scientific principles...

Ah-hem...

>>> Nothing to concentrate on at the moment, save for Frances. Everything else takes a back seat

Not everyone on these boards lives below the mason-dixon line...while I don't expect Gaston do reform into anything more than perhaps a weak TS, it is spawning at last count, 9 tornadoes in VA, and could spell some real flooding troubles for the Delmarva, then Joisey, LI and the New England colonies. Sure, Frances is occupying all of our minds (mine included), but don't say there's nothing going on. As HF opined a few posts earlier, there is the potential for a Fujiwara-type interaction between Hermine & Gaston, albeit over too-cool-to-support-development SSTs, but still, huge flooding could be a problem.

That being said, I'm not going to pick a potential bullseye until Wednesday at the earliest, though my original call for Hattaras is probably going to be a crow munching spectacular. Not that I haven't had those before. One thing I do believe will happen, no matter where Frances eventually landfalls, is that this will recurve and spell potential trouble for the entire east coast. I do not think for one moment that this will cross the peninsula and get into the gulf. In fact, I'm still not 100% certain of a FL landfall, although there is not one shred of evidence to dictate anything to the contrary. Just a gut hunch I get with these CV longtrackers. I've been proven wrong many times before, so it's no big deal. We'll know with a fairly confident certainty, on Wednesday. As it is, everyone from Key West to Portland ME needs to keep an eye on this. Anyone in the space coast region especially, but everyone.

Then we've got what should be 99L (97L) to think about, plus some possible homegrown mischief in the GOM, but those are for the future. Gaston...Hermine...still making some mischief for some.

Let's hope the site can handle the hits come later on in the week....

As LI phil said the remmants of Gaston could produce very intense downpours, there is a cold front to our east that will generate convection cell thunderstorms and rain, cold fronts and tropical mositure just don't work, like electric and water. Also the threat for tornados is still possibly as moves into the penisula and LI. We still have time for Frances, lets focus on the current systems impacting our lives.

Watching in Miami. Don't like the trends. (Who in Florida would?) Don't like surface analysis for 72 hours out.

Don't like wording in last discussion.

Said before.. if it doesnt veer nnw along the coast would be a big problem for wpb/melbourne.

That being said...for the first time on local news I saw a 3rd scenario where the high is strong as in 72 hour pic and it pushes storm through straits and north coast of cuba. First time Ive seen anyone give that one.

As much as I said WPB/melbourne.. my confidence in my own words is real low

Think we have surprises in store from Frances and not good ones.

Hope I'm wrong.

Hear all the holding to SC line but... its getting harder and harder to see how its going to get up there from this vantage tonight after it went so far west so fast and there won't be much of a path from Gaston/Hermine left in 3 says.

Scary thought.. I really hope we don't see her come ashore, hook right, and continue right up the middle of the state.

If I read your message correctly, are you suggesting a more northery turn like the current UKMet model suggests?

A Cat3 with Tampa/St. Pete on the west side as she moves to the Gulf could cause major flooding problem here. I haven't seen any models suggesting the impact of such a case - just general models showing a cain coming in off the Gulf. But Josephine in 1996 (5.5' surge) is one I remember with a ton of flooding. I would guess Frances could easily top 5.5' of surge here.

Oh Heck...the problem I am now faced with is which direction to plan my evacuation? Everything else is falling together with boarding up and supplies. My landlord said he started searching for wood at 8am in Merritt Island and went as far north as Titusville and south to Melbourne with no wood or the snap ons left anywhere. Supplies are being held until they get a better handle on the hit area and then they will be shipping in the wood and such to those areas for boarding up. Thank goodness i still had my wood from floyd. I was planning on heading south west. Hotels are already booked going north, Ga, Alabama, already filling up. So....where do you go to get into the safest area?? Any ideas?
I urge everyone in the area, on the east coast, get ready now. You will certainly be doing yourselves and your families the best to figure on a hit, prepare for a hit, and if it does not happen, dance happily. Its only supplies, not lives.

I not only tend to agree, and sympothise, I also share it living on the East side of Orlando. I'd invite you to my place of shelter, but living in a mibile home, I don't expect it would do either of us much good. Charley got 10 trailers, Frances will likely clear the rest. My boss' home in S. Orlando stood up well, so I'm gonna honker down is his garage with my belongings and hope it keeps its' roof this time. We should physically survive, me and my cat, but I have a real feeling this will be a sellers market for anyone that has any places to stay left standing to sell. FEMA mentioned 8000 trailers to help the homeless from Charley...It had better have 3-4 times more ready to go after Frances gets her shot. I hope it does NOT make it here, but I'd be deluding myself If I said I believe it won't. It hasn't happend yet, might not, but I will say I have my generator and batteries already in my likely new residence....moved them today 'cause they are too big and heavy to do at the last minute. This tin box survived the Eye of Charley, but even a glancing blow from Francis might well be the preverbial straw. If the data on Wednesday looks anything like it does now, I'm outta here for thicker walls. Darned...we just got power back the other day too....shoot!

Much too early to make that deicision, unless you just head to some place like Kansas.

However I would not try and go South, because there are just so many people here that will need to get out if the track shifts left, and you will be caught up in the biggest evacuation in history. But given the current track, and possible shifts of that track, there is no state in the SE US with a coastline that is 100% safe. Also SW of you is heading into the Charley path, not a good place to try and find shelter.

I know this sounds kind of lame, but just chill out and wait a couple of days.

Charley vs Frances

thought I would go back and look at how the NHC handled Charley five days out, and then when they actually nailed the right spot at the right time.

Unfortunately, Charley did not have an advisory five days before it hit Port Charlotte, so I looked at their four day forcast. The NHC forcasted it to be at 19 N 81.5 W, or approximately 350 miles south of Fort Myers, at 8 a.m. on Friday August 13.
per the closest advisory, the storm was actually at 25.2 N 82.8W.
On tuesday morning, the NHC called for the hurricane to be in the middle of the gulf in five days. Finally, by Tuesday afternoon, Charley was thought to hit Florida in the panhandle.
Finally, by Wednesday, the NHC said in three days it would hit the west coast of Florida.

Now, here's my thoughts. The NHC isn't kidding when it says its average error is 350 miles on five days out. Charley is a tough analogy, because five days before landfall, it was just a depression and Frances is a full-blown hurricane.

But the point of this excersise was to say that while it has Vero Beach in the bullseye now, a 350 mile error could put it in Cuba and miss the US all together. We just don't know.

I looked at Isabel when it became a 110 kt hurricane. The five-day forcast: 20N 63 W.
The actual five day location: 22.6 N 62.6 w. That's a lot closer.

Frances Locally

All 3 major W.P.B. tv stations have gone to updates on Frances every hour on the hour. Almost everyone in my neighborhood was cutting tree branches down this evening to put out in tomorrow's trash pickup. The stores are starting to get crazy. People went to work this morning seeing the track shift eastward over the Atlantic and came home tonight seeing it bend back towards them. One station this morning even went as far as saying it looks much better this morning than it did yesterday, looks like we will be lucky. I guess they are already eating their crow within 12 hours of that statement. Way too early to tell people stuff like that.

Oh Heck...the problem I am now faced with is which direction to plan my evacuation?


In the increasingly likely event that almost any of the 'somewhere in Florida' tracks including the current NHC forecast pan out, plus or minus a hundred miles, this just in:

HURRICANE FORCE WINDS EXTEND OUTWARD UP TO 70 MILES...110 KM...
FROM THE CENTER...AND TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP
TO 140 MILES...220 KM.

That means essentially the entire state will see hurricane force winds...this babe is 140 miles across in the windy zone and 280 miles in the breezy zone. If it does hit MLB, Orlando and Tampa will already both be experiencing hurricane winds and points south to about FLL would probably feel them also. A miss to the East of a hundred miles would still allow ORL and JAX to get 74+ winds not to mention the 'worlds most famos beach', the oldest city in the US (they say) and of course, the home of the shuttle. Someone today at work said 'that is a bit negative isn't it Mr. C.' I said, no, it's not negative, I'm positive the brown muschey stuff is gonna hit the fan, and we don't even need the fan.

Someone asked a bit ago, "Where can I evacuate to?". I'm sorry, it really looks like unless you have friends in Texas, you could have Frances stuck to your posterior from NY to LA depending on track. There really isn't a good answer except to start looking now for high ground, away from water and in a building with good construction and thick walls, have plenty of candles and non-perishable food on hand (and tied down), and most of all, several gallons of drinkable water per person. Water, drinking water, may be the most valuable item after shelter. Medicine, pet food, clothing and blankets could come in handy for a lot of people within 50-100 miles of wherever it comes ashore. Oy yeah, and pray, if you believe it will help, that no tornados touch your hiding hole. ... and do it yesterday, not waiting till everything is sold out. Oh, and don't forget the stinkin' can opener!

NRL, RNC

Bugs, both my main link to the NRL & my FNMOC backup are down...can't imagine why.

>>> I wouldn't even venture into the city today even, us (LI Phil and me) are very worried about the fate of the city.

While I agree with the first part of your statement, about not venturing into the City (dats what we Lon Guylanders call it), I'm not particularly worried about the fate of the city. RNC, US Open Tennis (which is right next to Shea Stadium), local baseball...what a mess.

Coupla things, as long as I'm posting. I'm not too confident in much with this storm (Frances), but I am pretty confident of two things. US Mainland Strike and eventual recurvature (ie no Gulf mischief). Whether she recurves prior to a Florida landfall is the $50 billion question. For all you under the gun, I sure hope it does recurve, but then you're just shifting the danger further north. However, since FL has already taken a CAT IV this year, I vote we shift the danger north.

Second, this storm will definitely regain CAT IV status...question is...what status will it be at as landfall nears? That too is the $50 billion question. As rickonboat stated earlier, CAT IV's can be catastrophic (I didn't know that), and the damage inflicted is not additive but multiplicative.

Until Wednesday at the earliest, all we can do is watch and wait (and for anyone under the gun, PREPARE!). I'm sure NHC will slightly shift tracks with each update. Listen to them...they are the experts. Gas up the vehicle, batten down the hatches, whatever you need to do...

And last but not least, as long as we're bashing Frances, did you know that Maginot means "Welcome" in French?

If a CAT 5 comes through Florida, which is not out of the question it would cause much more damage then a CAT 4, because the strength of wind is doubled by it's square or something along those lines.

He's baaaackkk....

Gaston's back -- the NHC put out a 7pm update to say that they will be issuing the next advisory on the storm, as opposed to the HPC, at 11pm. Their webpage now references Tropical Storm Gaston yet again, as opposed to Tropical Depression Gaston. I think the center is trying to reform a bit further north, nearest the strongest convection south of the D.C. area, and would not be surprised to see a minimal tropical storm for a day or two over the Atlantic.

Other topics of interest -- Hermine is basically shooting out from it's convection and well on it's way to being declassified. Don't think it has too much longer before it's done -- and I'm not even sure it'll make much of an extratropical system either.

Frances is the big topic, and one on which I'm going to ignore the FSU football posts here as they aren't relevant. If the storm goes through here, the game just gets moved to later in the season...and no, the model here has no "football coefficient." In any case, the storm is going through a minor period of flux while the new, larger eye gets itself together. Later tonight or tomorrow morning, I expect we'll see a storm looking a lot like Isabel did last year with a large eye (last recon reported a 45mi eye), albeit at a weaker intensity. For now though, it has been obscured.

The upper low to it's west is retrograding to the west and I expect it to either dissipate or, at the least, not have a major influence on the storm; right now, the ridge is building in around it. The trough to the west may be held up just a bit by Gaston, assuming it lingers around a bit. It will pick up Frances at some point -- but when is the big key. Frances still could miss the coast entirely, but that possibility is growing slimmer by the hour. The GFDL keeps trending west, the AVN is still pretty far south, and the UKMET takes the storm in over Miami and then up Apalachee Bay -- not a good scenario. Coupled with the FSU Superensemble model I referenced before and talks with some people here, I feel like Florida is very much under the gun from this one. Everyone up and down the coast needs to be wary, but those in Florida - east, west, and Gulf coasts - need to pay close attention. Model consensus right now says Cape Canveral and the Superensemble says north Miami. Intensity? Most models are near the cat3/4 level in 5 days, with a peak just before then. In other words, this could be the first year since 1916 - and first unambiguous year since before 1900 - with two U.S. landfall cat. 4+ storms.

In other words -- stay tuned.

The invest off of Africa is decently organized, but it's pretty far to the north and I think the mid and low-level circulations may well be separated by a few degrees of latitude -- that or the thing shooting west ahead of the main convection is a figment of my imagination. It's got developmental potential, but is most likely one for the fish and not something that will develop rapidly (if much at all). If it doesn't do it soon, it'll meet it's demise in the westerlies near 20°N. The wave just off of Africa has more potential to be a long-tracker; the GFS particularly likes it, while other models pick up on something out there. We are near the peak of the season, so anything's possible.

It is better to wait and watch rather than to cause what might be unecessary panic. Not to make lite' of everyones concerns, but we have a couple of days. Let the professionals guide you in your evacuation plan. And be careful even at that. Charley fooled a few out there in the 11th hour. With Frances fluctuating in speed like today, the forecasted models will vary more than a storm that has a more consistant speed.

Re: NHC Track

Here is an email I received at 9:30 pm from a friend who is a meteorologist. What do you guys think of it?

Hurricane Francis seems to be experiencing less SW wind shear at this moment and eyewall reorganization/replacement seems to be finished for now, so she may be slowly strengthening again. As I forecasted though, it's pretty clear that she will be north of 20 deg. north latitude when she reaches 63 deg. west latitude. So at worst the northern Leeward Islands "will" experience tropical storm force wind gusts. She still has to fight some shearing though through approximately 70 deg. west longitude, so I do not expect rapid strengthening to a CAT 5 in the next few days.

I'm getting an enormous amount of email from old customers, friends, storm chasers and even foes but have really said little about Frances other then on a couple of hobby weather eGroups. BUT if I were still in business I would be warning customers of a better then 60% chance of landfall on the SE coast of Florida next weekend. A Miami to Fort Myers track or maybe a Ft. Lauderdale to Sarasota track, hard to say that far in advance. A landfall forecast error of under 200 miles would be pretty good this many days out.

I've looked at all of the models again today and I see a continuing westward track bias. But as most already know I feel that if you live by the model you die by the model. But if you ignore what the models say about an actual track for Frances and look at what weather systems are in place now and what's being progged at mid levels over mid latitudes in North America, it's a no brainer. My hoped for mid level weakness to be left behind by Hurricane Gaston and Tropical Storm Hermine will not linger or even exist. And the strong longwave trough will be out over the western U.S. and unable to eject shortwaves SE-E'ward due to strong ridging along the U.S. East Coast . Hurricanes turn NW into troughs when within approximately 10 deg. west longitude. So there is nothing to turn Frances NW-N east of Florida like I originally hoped for.

BUT what does a lower latitude more westward track mean if it continues to occur? The good news would be a close brush with Hispaniola and/or Cuba. This close brush would continue to inhibit Frances' growth to a CAT 5 cyclone, even knock her back to a CAT 3. Also like with CAT 4 Hurricane Charley coming ashore in SW Florida, speed divergence could pull Frances' eye wall onshore into one of the Great Antilles further disrupting the cyclone.

We can also hope for an unseen unprogged disturbance in the subtropical jet stream sneaking in under a dirty ridge to turn Frances NW-N east of Florida but that's unlikely.

A note though, last year while in semi retirement I committed to a similar forecast on Hurricane Isabel making a landfall on the east coast of Florida, when she reached approximately 22 N 60 W. At this time though Frances is at approximately 19.5 N 60 W, but that southerly difference in latitude can make all the difference. In any event last years forecast brought upon me a blistering attack by the media and colleagues. I was even accused of being obsessed and neurotic.

Once again though I add this disclaimer. As I've officially retired from space and atmospheric weather forecasting, confidence in my forecast of tropical cyclone path and intensity is lower as I no longer pay for real time raw weather forecasting products.

Great post as always. Since everyone else is talking about Frances, I'd rather comment on the rest. I did not think we had seen the last of Gaston, and think we might get 24-48 hours of a TS still. As far as the invest, I agree with you, and I don't think it is a figment of your imagination (either that or we are both imagining the same thing). This system is literally all over the map.

I live on South Merritt Island (between Melbourne and Cocoa Beach)...the house was built after the new March Hurricane code and was build to withstand 130 mph winds. I also added the heaviest aluminum panels for all coverings which are rated for Cat 5. The flood maps say it would take a Cat 5 to flood here as we are one of the higher locations on the island. My question is this...what threshold would you evacuate for...I am thinking about 110 to 120 mph. I am worried that we won't find somewhere to evacuate to and get caught on the road.

Its a valid worry. I spent a lot of time in Wachula after Charley and I know they have old Building codes but I saw brick buildings demolished.

I could see this thing doing like Hurricane Erin in 1995 (or Andrew). Going over South or Central Florida-and entering the gulf to make a second landfall.

It could hit FL then skim the coast up to the Carolinas.

Could miss Florida altogether and hit the Carolinas AKA Floyd?

Who knows?

I think it's going to stay South of where the track is and hit near the Florida Keys.

Re: NHC Track

The Florida Division of Emergency Mgmt. has a hurricane evacuation map available through their public mapping tool at:

http://public.mapping.floridadisaster.org/PublicMap/index.htm

You will have to zoom pretty close in on an area of interest to be able to check the "Evacuation Zone" map. You can also see storm surge maps for the coastal zones as well.

For instance, the Merritt Island area is rated, in parts, at Cat 5 storm surge, but the entire area is rated as evacuation for a Cat 1 storm. It's entirely up to the person there to make the final decision, but knowing that area at least somewhat well, I'd be inland if a storm was threatening - at least in Cocoa or Melbourne or someplace off of the islands.

The map is a pretty useful tool for those of you in Florida; if you get a chance, check it out. It requires you to install a plug-in from Autodesk, but it's not spyware or anything (for those worried about that).

Re: NHC Track

I have to laugh at how ill prepared I am for this season and how glad I'm not in Florida. I live in a sea level house whose streets flood (my driveway/carport is 1' below street level). We moved last September so outside of my first aid kit, I don't have a clue where any of my other supplies are: hatchet, flashlights, etc. I have no emergency batteries. I have no reserves of water. I own no plywood. My house is surrounded by old pecan and oak trees. I don't have cigs or booze in reserve. We don't own a generator. I've been slacking. We don't even have any ice or charcoal. LMAO. Use me as the 2004 poster child for what happens when you don't prepare even though I've got a feeling I'll be heading out to the supply store sometime in the next 3 weeks to cover my a$$. But Plywood isn't an option. I have too many windows and wouldn't have the time to deal with it anyway.

Poor me? Poor you. My call was for southern North Carolina and I'm prepared to go down with the ship. Should I be wrong (no fudging with 3 and 5 day forecasts as I go along, this was from last Thursday), chances of a somewhat rare SE or SSE hit on peninsular Florida could be in the offing. Problem is, this won't be our last hit. I'm sure we'll see 3-4 more CONUS hits before late November. Be sure to hedge in increased homeowner's policies next year

Re: NHC Track

Rabbit, if the NHC "first call on landfall" is anywhere close, you'll be eating crow with your statement of "I am certain the winds will not exceed 100 mph."

The 11pm forecast advisory brings the center to 28°N/81°W at 5 days, inland after hitting the coast as a 120kt hurricane. Where is 28/81? Orlando is at 28.5/81.3, so that places it just south-southeast of Orlando by about 30 miles to the south and 18 miles to the east...think Narcoosee, FL. That'd put the storm passing just to your south.

For those of you all in the Stewart fan club -- he's got the 11pm package on Frances coming up shortly.

Gaston has been reclassified as a T.S. about 50mi SW of Ocean City, MD, while Hermine is still being carried as a T.S. based off of buoy data south of Massachusetts. It (Hermine) is nearing landfall, but at this rate is bound just to kick up the wind a bit with some passing showers. In fact, many people there are bound to think what the big deal is about, as they may well receive no rain from this system at all.

A few new watches/warnings are up for Frances, mainly in the big islands, with potential T.S. watches for the Turks & Caicos tomorrow.

Re: NHC Track

I'm not a big fan of cutting and pasting information, but this tidbit from the 11pm discussion bears watching, from Stewart:

"...THE OFFICIAL FORECAST TRACK REMAINS CLOSE TO THE PREVIOUS TRACK AND NEAR THE NHC MODEL CONSENSUS. HOWEVER...WITH SUCH A LARGE TROUGH FORCAST TO DEVELOP OVER THE CENTRAL U.S...IT WOULD NOT SURPRISE ME IF SUBSEQUENT MODEL RUNS DO NOT BEGIN TRENDING A LITTLE MORE WESTWARD. THE NEW 00Z MODEL RUNS SHOULD BE INTERESTING."

Here's where this thinking comes in...

1) There is already a sharp trough evident in water vapor imagery across the east-central U.S., and there is energy riding over the ridge in the western U.S. to reinforce this. However, with the strength of the subtropical ridge, it is likely only to amplify the trough and not move it eastward.

2) With a deepening trough in the central U.S., there has to be a corresponding strengthening on a ridge somewhere to compensate. This is likely to be in conjunction with the Atlantic ridge. Add in the gain in intensity you sometimes see of the ridge as a tropical cyclone recurves around it's base - here, Gaston - and this is very plausible.

3) The 00z model runs that arrive about 2am (& later) will include yet another series of Gulfstream jet data from earlier this afternoon. Any and all additional data is going to influence the track forecasts in a positive way, and with a better sample of the environment, the aformentioned shift in the track may well be verified.

I can only hope that the NWS is having all eastern and central U.S. NWS offices launch 6hrly baloons for upper-air observations, as there is a noted increase in forecast ability with increased upper-air data across the United States. If we did thus on a regular basis again, our forecasts would be twice as good as they are now (and that's just midlatitude weather I'm speaking of)! But, I haven't heard of any plans to that effect yet.

It sure will be interesting to see the 00z model runs, but again - it's not a point storm, it's a big storm.

Back on Friday I think the GFS model showed Frances going into Mobile Al Bay, which brought quite a chuckle from me at the time..... four days later.... and looking at the lastest NHC hurricane track..... it might not be that far off after all.... from what I heard and read tonight via other news sources and web sites..... I would not be surprised to see the track move south and west over time..... what a challenging storm to track.. guess we'll see tomorrow if the ridge is going to be stronger than earlier expected and shift the track more to the left.... I'm just gawking at all the changes in track like everyone else... but I still like my Kennedy Space Center and somewhat south target areas as I told Steve and Phil a couple of days ago... so does the NHC right now too, but IT will change no doubt

Re: 84hr 00z TropEta

Looks to have the GOM written all over it now doesn't it.....

I have to add that this is based on the ETA model..... which maybe is reading the strength of the ridge being reinforced

I am not saying it will go into the GOM.... only what the model appears to be trending....

Re: 84hr 00z TropEta

Jason: any idea where the previous ETA model, i.e. the one without the benefit of the new data, had Frances at approximately the same time?

Thanks for putting that up and apprizing us that it included the new data -- I've seen a lot of helpful stuff on this board today, but your last post was the most helpful.

Previous 84hr

Be aware that this is not the same exact time...this is 6 hrs earlier than the current 84 hr I posted above...but you can tell that the Eta is much faster and further south...a sign of the stronger ridge.

This is the link to the same time period on the 00z Eta...

00z Eta...same time as above

For what it's worth Channel 2 in the Orlando market just did a five minute spiel on 3 different scenarios, but the other two from what I see aren't as alarmist.

Too bad I don't need overzealous mets to be alarmist about this. Even after taking the worst Charley had to offer for the east coast i'm not taking this one lightly.

My thoughts...

I'm not sold on ANY track yet...but I do consider the possibility of this being a Gulf storm much more likely than if you had asked me at 10am this morning. My initial gut on this storm as early as this past weekend was for a Miami/West Palm landfall (in fact, one of the members of this board has an e-mail from me to prove it! )...I backed off of that a little bit last night and today, but I am starting to get really concerned about a S FL, then Gulf strike. The trough in the central US, as so ably described by Clark and Stewart, is digging quite well, and will reinforce the ridge over the W Atlantic.

BUT....I can and have been wrong too many times to count...while this progression of data is better news for JAX or the Carolinas, NOBODY is out of the woods yet. Pay close attention the next few days!

Re: NHC Track

The only thing that really stuck out was the fact as I flipped to the TV station in question, I saw a huge graphic stating in large letters "Saturday 140+ MPH winds"

Not everyone is as savvy as members of this board, and I know several people who will construe that as "OMG that will definetly happen now! It's all over"

My opinion aside I agree with you, more coverage is better. I just think the stations in this market need to state that there is room for error more clearly and concisely, IMO. Maybe it's an overcorrection for the local stations being late about Charley.

That's just my two cents. I'm definetly not a Meteorologist, but i'm studying to be one.

I'm hoping for the ever decreasing possibilty of the hook for this one.

Well, I guess that cancels my escape route to North Georgia, huh?
That is honestly a nightmare scenario. Up the state all the way from one end to the other? I surely hope that does not happen. The other problem I see with this storm is it's current movement @ 13 to 14mph. That gives us much less time to do a whole lot. Hopefully any visitors that plan on making a Labor Day Weekend vacation in Florida are paying attention to the news.

The good news is that we have a shelter here right across the street at our local highschool.

Re: NHC Track

I didn't watch Fox 8 @ 9 but someone reported that Breck is thinking Frances may clip the keys and then head for Fort Walton or Panama City Beach. I guess it's plausible. He based his hunch on forward speed and strength. Apparently he thinks it's going to be a powerful storm. All I'm going to say is that Frances is turning into a pretty ominous threat for the United States. With Charley, you couldn't be sure of what he had until hours prior to landfall. But anyone can see where Frances has been and what her potential is. I wouldn't want to come off as being too alarmist, but someone's (and quite possibly) a lot of people are going to pay.

I read a report out of Newport or Richmond where there were 10' of water in some buildings (11+" of rain in a short timespan). Gaston turned out to be a major story throughout SC, NC, VA and will be beyond. Bastardi thinks TS conditions in New England. Pretty trippy. Wet storm followed by a powerhouse storm.

And oh yeah, in case you haven't noticed, 2004 is shaping up to be the all time sickest troipcal season and we're not even in September yet. /food for thought

I don't get it. 0Z GFS has Frances about 350 east of stuart, FL, after movng almost due north from the eastern tip of Cuba (at a latitude of about 25 N), cuba used as a reference point. the 0z ETA has it going over central cuba west!!!! Somethings wrong with this picture. GFS shows Frances moving north into a building ridge to her north!. Question here is does the model turn her west again towards the FL peninsula!!!!

Re: Glenn Burns(11pm news update)

Glenn Burns from WSB-TV here in Atlanta seems to be the only on-air meterologist taking Frances very seriously. His latest prediction is that Frances will hit somewhere between Jupiter and Melbourne on either late Thursday or early Friday, head up through South Georgia and park over Atlanta for the weekend....If this stationary front doesen't skeedaddle out of here soon, Us folks in Atlanta may be looking for Noah and his animals walking down Peachtree St. I think the next 24 hours will tell us when and where, and knowing Glenn's track record, I would go with his forecast over the other three TV Stations here.

Now, Atlanta is not on a coast and very rarely gets hit by tropical storms, but with the world's busiest airport here, it could mess up airline traffic for most of the US over Labor Day weekend..... :?:

Re: something you dont see everyday

Well, yes, the GFS has a different track, but the reasoning and synoptics are different than the Eta...the GFS has a weaker and more progressive ridge that only briefly builds south and then ejects to the east, allowing Frances to turn in it's wake. Interesting, to say the least, but I ain't convinced...at least not yet....this GFS run really evolves the ridge/trough pattern differently than prior runs, as well as the Eta...not saying it is wrong, but it is different.

Re: something you dont see everyday

GFS actually not only misses florida on new ooz model run but only scraps the bahamas with TS force winds and moves it NNW with possible landfall in 6 day near the outerbanks NC.
Lets see 2 more runs of this to think this might happen due to weakness in the mid atlantic states and the ridge weaker out in the atlantic. Other model runs coming in.

I can't even imagine what would happen if a dam broke. Especially in the middle of the night.

Hope that dam holds up. Gaston is dumping tons of rain on Virginia. It was a slow moving wet storm. Goes to show you that sometimes it's not the winds but the rain that can cause a lot of damage. For all his wind, Charley did not dump much rain partially due to his rapid speed as he crossed the state.

A week ago Saturday my Mom woke up to find out the cables on the boat dock had snapped and it was floating down into the cove, both boats attached. I think they have just gotten so much rain that it just couldn't handle anymore, and my Mom said that they had a really bad storm the night before. Atlanta might not be on the coast, but it sure takes a lot of beatings from tropical weather.

What you are seeing is the TUTT, or a Tropical Upper Tropospheric Trough, that is behind Frances and helping to ventilate it. It is really not a steering force, as the trof is expanding a bit as Frances is moving away...in other words, Frances is affecting it, not the other way around....

Re: Charley's Track and the Models

Scott...when Charley was just beginning to look as though it might be a real threat to Tampa, Dennis Phillips said, "If the model runs are still the same this time tomorrow night, we may be in real trouble." That was on Tuesday, and on Wednesday they were still the same. This is an all too familiar reminder of his thoughts. Even though it made landfall south of TB, it was only off by about 70 or so miles, which was in the cone.

If I hear that tomorrow, I'm going out to restock what we used. The track has been trending left then right then back left again, but it really hasn't changed all that much and now with the forward speed moving faster, they're talking about 8:00am Saturday instead of 2am Monday. That's also eerily familiar.

Remember how the pressure had dropped but the winds didn't catch up until right before landfall? That caught everyone by surprise. So the wording "a conservative estimate" used by the NHC when talking about the winds makes the hair on my fairly small head stand up on edge.

I want to say this about our local mets: we have some really good ones and they sure worked around the clock with Charley. However, Dennis Phillips kept plugging himself with the line "we were the first ones to tell you this" about the track change, yet it wasn't until a few really ticked off viewers from the inland counties made him realize that just because it was not going to devastate TB didn't mean that the interior counties were off the hook. It actually took until almost 2:00pm for him to start talking TO the inland counties. BayNews9 noticed the change in the track an hour before they did and also the impact it would have on the inland counties.

I guess what really gets my goat is when a weather person keeps patting themselves on the back (he's still doing it) for doing what he's supposed to do in the first place. It's like a fireman going on TV telling everyone that he put out the fire first. Of course they do, that's what they have to do. I just don't like the "I was the best and the first" plugs. Especially when they weren't.

Now, why I ever went off on that rant is beyone me, I suppose I'm just tired. I guess I just want people to tell me what's going to happen and what I can expect without having to listen to them tooting their own horn.

I think I'll go do something that I didn't do with Charley: get some quality sleep time in. If I learned one thing from Charley, it will leave you physically and emotionally drained just when you need to be on top of the game.

BTW...you and Jason are doing a great job keeping us up to date on the latest model runs. Thanks to both of you for doing such a great job.

Re: Charley's Track and the Models

Just logged in. I'll have to say I second the kudos to Jason and the gang for the updates. You do a great job here.
I noticed the NHC has added quite a few FL cities to the Strike Probs. Since I'm not much good at the models, I went back and checked their stats against Charley. NHC had Venice/ Ft Myers with the highest prob up to 36 hrs prior to landfall. I realize that just means that the possibility of the storm passing within 65nm was there. However, both of those cities continued to get higher probs. when NHC was giving Tampa lower probs. That's just my opinion and not necessarily those of the management. It may be a storm by storm situation. They hit dead on with some and miss with the others.
With that said, Miami and West Palm both have the highest probs as of the 11pm Advisory. Both have a 7 in column 'D'.

This is one of the most radical changes I've ever seen in a six hour period. Really goes completely against the NHC 11pm forecast, as well as most of the eariler globals.

Joe, judging from the number of dropsondes they released today I would venture to say they obtained quite a bit of extra data. I'm not sure if the data from that kind of dropsonde is comparable to the Gulfstream IV drops data. There should be some format that would let them utilize both types. Just my opinion.
Satellites are back up and Frances looks quite a bit healthier than at 0345Z.

That looks to be due west of the eye, at the western edge of the cloud mass. I'm not sure what 300mb equals in altitude, but it's fairly high. This is from the last recon observation at 0620Z.
**Clarification-this IS Not the new position, just a reporting position on the way into or out of the storm. They have to send a report every 20-30 minutes or so, with data in it, and that position was where they were on their way out it looks like. They make all kinds of criss-crosses and zig-zags sometimes.**

Naahhhh....that was a recon leg report, not a vortex center fix....the center of Frances is NOT at 21N, nor is that what the message says...the highest wind gust for that leg of the run was in that position.

Re: And just to stoke up the fire a little more....

Sorry about that! I went back and put a clarification of the bottom of the post.
They have 105nm legs they fly, criss-crossing the storm. The 105nm is not set in stone and they can alter the leg as they see fit. There are about 5 different patterns they fly and they appear to be headed out of the storm to turn left and make another pass through the storm. I'll see if I can find a link for you to look at.

Better link, with more patterns.

Re: And just to stoke up the fire a little more....

with the pressure of Frances bouncing around everywhere (948, 956, 945, 951) and not showing any general trend of continuous dropping, it is looking less likely that Frances will reintensify to Cat IV

It also appears now that it will take the more southerly track as it has been moving nearly due west for about a day now

Re: And just to stoke up the fire a little more....

That dont mean that it will track more on the southern route, the models overall moved more N and E but slightly. GFS is the biggest mover to the NE while the Nogaps moved more w slightly, CMC is also a tad more N and Ukmet is about the same. Will throw out the ETA but it could be right but a tad more N of that. The models all predicted a w motion up to this morning with a turn wnw during today, lets see when it does.

The coordinates are near downtown Orlando, maybe just SE a tad, the 120 hours is relative to the time of the forecast (Makes it late Saturday) and is based upon current and forecast speed. Errors noted say the distance can be a few hundred miles off by Saturday (Mia to Jax) and the top speed could be off by quite a bit also. Timing assumes speed is as predicted so could get here much earlier or possibly later. Bottom line, pay extra attention to this forecast, but be prepared for significant changes also....start your preparations now and be ready to take evasive action if required by Friday. Other than moving to safety if that is needed, you should already have your supplies and plans firmed up or completed.

Thanks. I live in a home that is supposed to meet minimum standards. Its a normal home. We have been prepared since Charley was expected. With the shifting models and the error disclaimers, I was uncertain about the coordinates. I have a lot family in this area as well. Its not that long until we have to start final preparations for what ever may occur. Is Wednesday still the definitive day or has that been moved to a sooner time for Florida to get a more concrete notion of what to expect. ( I know from Charlie that this is a general answer no matter what)

The NWS Melbourne's office has a great tool where you can point to a spot on the map. It gives you a forcast but also your location.
Apopka is 28.66 N 81.5 W. So, if this forecast holds true, I would be about 9 miles to the north of the center. That would put it at about Windermere.

Great discussion from Tampa

This is about the best description of anyone yet.


AS FOR FRANCES...JUST WHEN THE MEDIUM RANGE SOLUTIONS APPEARED TO
CONVERGE...OFF IN THEIR OWN WORLD THEY GO ONCE AGAIN. AS OF THIS
WRITING...THE ETA...CANADIAN AND NOW NAVY NOGAPS MODELS WERE FARTHEST
SOUTH. THE ETA HAS FRANCES ENTERING THE STRAITS BY 12Z/FRI WHILE THE
CANADIAN/NOGAPS STEADILY MOVE IT ACROSS THE PENINSULA FROM SE TO NW
ON SATURDAY. MEANWHILE...THE 00Z UKMET THRU 72H APPEARS ON TRACK WITH
THE CURRENT TPC FCST.

THE BIG CHANGE...AS WAS THE CASE THIS TIME YESTERDAY...IS THE GFS
WHICH FIRST SLOWS FRANCES TO A CRAWL OVER THE CENTRAL/N BAHAMAS
BEFORE TAKING A DUE N MOTION INTO THE SE U.S. (CAROLINAS). ALSO JUST
LIKE YESTERDAY...THE GFDL IS IN VERY GOOD AGREEMENT WITH THE GFS.

THIS TIME...THE KEY PLAYER IS WHETHER A WEAKNESS IN THE WESTERN
ATLC RIDGE DEVELOPS OVER FLORIDA AND THE WESTERN BAHAMAS ON FRIDAY
WHICH WOULD ALLOW FRANCES TO PULL UP AND WAIT FOR THE SYSTEM IN THE
GULF OF AK TO EJECT INTO THE NORTHERN ROCKIES AND EVENTUALLY THE
GREAT PLAINS...WHERE DEEPENING AMPLITUDE INCREASES S/SW FLOW THAT
EVENTUALLY (BY SAT NIGHT OR SO) PICKS UP THE CYCLONE. THE GFS/GFDL
SHOW THIS WEAKNESS WHILE THE ETA/NOGAPS/UKMET DO NOT.

SO...SHOULD FRANCES BARELY SLOW DOWN...THE FARTHER S SOLUTIONS (MORE
OMINOUS FOR FLORIDA) LOOK BEST. BUT...IF FRANCES SLOWS TO A CRAWL
WHILE IN THE BAHAMAS...THE CHANCES FOR A FLORIDA LANDFALL DECREASE
DRAMATICALLY.

HOPEFULLY...WE'LL BE ABLE TO HONE IN ON A SOLUTION THIS TIME
TOMORROW...ESPECIALLY SINCE THE HOLIDAY WEEKEND WILL BE "IN SIGHT".
STAY TUNED...

Just Be Prepared

The wise thing to do is to have on hand all emergency supplies, necessary material to cover your windows/doors, sandbags, non-perishable food stock, water, a generator / cell phones.batteries, etc.

Also have Plan B ready to be implemented once the 3 day (72 hr) window is upon us and that would start Wednesday evening.

Remember that Frances' speed will change as well as other variables that make up the models' calculated path; hence, don't agree totally with the current path as we are outside the 72 hour range.

Sit tight and be ready to implement Plan B.

Some of the models show a Floyd track. Others show it hitting Florida. I think this is going to be very much like Floyd in that we won't know if it is a hit or a miss for Florida until very late in the game.

I will do that. The Tampa post sounds like the most reasonable solution to all the questions so far. I am as prepared as I can be under the current circumstances. I don't however have a generator. Hopefully that is one purchase that won't have needed to have been made. I do feel better about going to work today and not having to read all the updates. It sounds like the Tampa report is the most reasonable.

Re: 5AM updates

The curve to the N may have something to do with a ULL out to W of FrancesThe ULL was expected to continue moving at the same rate as Frances to the W.Since last night is has not moved.The distance between the the leading edges of each system is 600 miles.Frances can either start the squeeze on the system like Charley did our go over the top.The latter I think would accelerate Frances alittle to the NW.If she chooses to squeeze the ULL she will slow down.See how the dynamics play out latter on today.

hole in the wall?

I hope everyone in South Florida doesn't wait for the High in the Atlantic to open a hole for Frances 24 hours before landfall. It certainly could happen - and might. But, what if it doesn't? Kind of like being under water with a 10 ton rock on your head holding you down and praying it moves so you can get up to get air.

I found the statistically significant Herbert's Box info quite fearful for South Florida. 90% +/- accuracy is a pretty high number. That should be enough warning for all of us (as we all haul butt out of Florida praying this is the one out of 10 'cain that misses us).

Re: hole in the wall?

Good morning all: another exciting day and the Hurricane of the moment continues west at 15mph...which should keep us interested...
I don't have the time for this but having lived through Donna in 1960 I wonder why the historic trac of that significant storm and this one are not being compared? The timing and the path are similar. The question that needs to be researched if possible is what if any similarity in synoptic features that influenced the trac of Donna exist in the current pattern
Can any one point to any graphic data that can quickly be accessed so we can look at that? This is not just an idle curiosity...
The influence of the ULL to the west on the trac of Frances cannot be under estimated. It has not retreated wes as much as the storm has advanced west and this can account for the GFS and GFDL stall over the Bahamas...
In my opinion if the ULL gets out of the way Frances will stay on a pathe slightly West of WNW into the gulf and a Donna like turn will occur as the trough approaches.

Hey Doug,

I'm in Bradenton, been here almost 1 year. I have to ask what do think the impact here on the west side of the state will be if Frances hits the east then moves out over the gulf? I realize it is early, but Charley was a little too close for comfort and it effected people as far out as Orlando.

Re: hole in the wall?

That DOnna graphic looks awfully similar to Frances --- I'm not convinced this storm is going to nudge as far north or "left of S. Fla" as some models want it too. The "weakness" in the high seems almost impossible if Frances deepens and creates herself a stronger upper ridge? Any thoughts ??
