Tropical Storm Ophelia Forms off Florida East Coast

7:30AM Update
Ophelia is still stationary off the east Central Florida Coastline, about 80 miles east of New Smyrna Beach and is expected, but not certain to, shove east and a bit north. Due to it being a little too close for comfort Volusia county schools have closed for the day.



The area is still under a Tropical Storm Warning, and a Hurricane Watch may be issued for parts of the coast later today. Take a look at the track models below for a good idea where it may go. Or in this case, we just don't know. The NHC's track is a best guess at this point, and they aren't even all that thrilled with it. So all of us along the Florida and Georgia coastlines will have to watch for any move this thing takes.

It has strengthened some overnight into a 60-65 MPH storm and may do so today even more, perhaps becoming a category 1 hurricane today. Overnight it flared up some, but this morning it has died back down a bit and has gotten more ragged looking, so this may keep it from gaining strength, at least in the short term.

Ophelia is still off our coastline. Most of the rainshower activity has been to the south, east, and north of the center of the storm. Still most likely it will move north and east, slowly, very slowly, and then eventually loop back around toward the west.

Some bands will make their way onshore today. With me personally having property right on the coast along New Smyrna Beach, you can be sure I'm watching this one very closely.

10:30PM Update
Tropical Storm Warnings now exist from Cocoa Beach to Flagler Beach, as Ophelia is about 90 miles east of New Smyrna Beach, still not moving at all since about 2PM this afternoon. It will continue to meaner for a bit, perhaps drifting north and looping around. It will need to be watched for a few more days, unfortunately.



More to come later.

Original Update
Tropical Storm Ophelia has formed east of Florida, Tropical Storm Warnings have been dropped south of Sebastian Inlet and now extend northward to Flagler Beach. The storm is moving slowly north and northwestward, and later on may loop just offshore of Florida.

This will keep Central Florida in the outer bands for a day or two. Beyond this, the highest chance is for it to move further away from the US, increasing to hurricane strength. There is some divergence in the models, some bring it back westward toward North Florida or Georgia, and most now move it out to sea.

Those in the area will want to keep watch on this one for any westward movement.

According to the NHC it has to do with the ridging in the north.

SUGGESTS THAT THE
GFDL AND ECMWF MOELS ARE BUILDING TOO MUCH RIDGING TOO THE NORTH OF
OPHELIA.

However, the only models runs I can find only 2 send her out to sea. The rest either put her across Florida or doing a loop and coming back towards the coast. None show it far enough in the future to see wether or not it actually hits the coast though.

Re: Tropical Storm Ophelia Forms off Florida East Coast

A number of things, the sterring currents aloft, the high pressure system to the north, with a divergence between the two systems could and I say could produce a system that gets kick out into the gulf. There were so many differences in tracks into Katrina, GFDL showed a more SW movement than any other models, that eventually came across FLA and into the lower keys, then out into the gulf. It's a guessing game right now, but I think forecastors are more perplexed more than ever, are cautiously watching this like a hawk.

Ophelia's "most likely" to move out to sea, but that most likely is relative. It's not a sure thing by any bets, Georgia is a second best, followed shortly by Florida. All are within the cone and range of error. The models are still split, and will be useless while the storm isn't moving much east or west.

I'd go with the NHC track on this one.

Re: Tropical Storm Ophelia Forms off Florida East Coast

the loop scenario from the other day is what's in play, i guess. most of the models have shifted that way and the nhc has a forecast track suggestive of it. doesn't look like ophelia will go onshore.. could get close to the st augustine area tomorrow... but during the weekend it should slide eastward on the base of a flat trough. ridge builds in over the top and should force an anticyclonic loop... and push the storm back to the coast next week. no idea what it'll look like then.. best bet is a low-end hurricane, based on climo. 'captured' storms of recent years include dennis in 1999 and jeanne in 2004... those probably illustrate the range of possibilities best. storm shouldn't have made its loop back until around the middle of next week, so plenty of time to watch it in the meanwhile.
nate will clip bermuda late tomorrow-early friday, maria is heading out.. none of the waves are looking particularly troublesome. the gulf feature isn't developing.. or at least should be onshore before it can do anything. models not showing a lot of activity, but continue tracking the 65w and 40w waves.. as well as the new emerging wave on the african coast.

Re: Tropical Storm Ophelia Forms off Florida East Coast

That is my take on that. I would not rule out the loop and a a more westerly track back towards the U.S.. The possibility is there, and is why forecasters are having a difficult time as well as the models. When a sysytem does not move much over time, how would the models move it if it doesn't have any input as to where the system could move.

Re: Tropical Storm Ophelia Forms off Florida East Coast

The models that take Ophelia north and then out to sea do that because they are biased in weakening the ridge too much. The northern motion of Ophelia the past 24 hours has been a result of the center reforming to the north. (there were two circulation centers yesterday). Now that they've merged a track to the west or west-southwest should begin. Latest satellite loops suggest this is already taking place. Ophelia will make landfall late tomorrow near Cape Carnaveral as a Category 1 hurricane. After weakening Ophelia will enter the Gulf and may threaten the Central Gulf coast.

Re: Tropical Storm Ophelia Forms off Florida East Coast

Dont look at Sat Obs unless you are looking at water vapor to see whats the flow in the atmosphere. Also dont rely on any 1 model cause they change from run to run and especially system to system. If you want to find a center outside of recon..radar and vis sat data are best. Never look for movement on infrered. Current thinking is that the NHC movement is alittle too slow, should make it further out to sea then 79.5W(4) days out, maybe 75W. Then a curl back to the wsw and w by sunday-monday.

I disagree with this statement of the direction of the system...the long range radar loop from Melbourne shows a slow NNW drift...the infrared picture represented could be showing the movement of the cloud tops and an expansion of the system...but the LLC is abreast of Caneveral and seems to be slowly moving to the NNW as stated...as per the radar representation.

Re: Tropical Storm Ophelia Forms off Florida East Coast

Ophelia:

I'm looking at the models, both intensity and track, and the sat image. Here are my opinions - don't take them as fact - I'm not a pro

Ridge to the north appears to be building. This will force Ophelia to stay south, looping it like the GFS, NOGAPS, and UKMET models show. CMC overweakens the ridge, allowing Ophelia to pass through. I don't see this happening.

Ophelia is showing signs that it is going to strengthen beyond SHIPS guidence. It is already a Dvorak 3.0 - that's just below hurricane strength. Based on this it seems all intensity models are low. GFDL...never even makes Ophelia a TS...clearly wrong. GFDI, GFTI, and GFNI keep Ophelia a TS for 3-4 days before strengthening her to a Cat 2 hurricane in a day...also doesn't seem likely based on what Ophelia has already done. SHIPS and related models bring Ophelia up to a hurricane Cat 1 quickly, but then plateau her and slowly weaken her. While this is possible, given the SSTs and the Sat view, as long as she stay's out to sea I don't see why Ophelia won't grow stronger than Cat 1.

The track is very important to intensity. If Ophelia does this loop that is forcast, it keeps her over warm water longer. The ridge that is forcing the loop is WNW to ESE, which is keeping Ophelia from swinging out to sea, and forcing her south. GFS long term (from NECP's site) takes Ophelia into the Georgia coast and back out over the FL panhandle...the latter point weakened probably to a TD before coming back in over Louisiana. I'm thinking the impact point will be a little further south...into Florida as a Cat 2, and the crossing angle WSW. From there, given a week to allow SSTs to recover from the cooling caused by Katrina, we could see Ophelia reach the gulf as TS and strengthen back to a weak hurricane before swinging north around the ridge after 2+ days.

Lets hope GFDL is correct and weakens this thing. I don't see it happening.

============================

GFDL:

Someone asked about the GFDL and Katrina in the last thread. GFDL was very good on the track and intensity of Katrina only after Katrina became a Hurricane. Before that GFDL just kept insisting on dissipating Katrina, and gave tracks that were widely disparate and erroneous. Becuase of these track issues before Katrina became a hurricane, the southward jog before the Florida landfall was dismissed.

Basically, GFDL seems to need a well established system to build a good track and intensity for. A TS that has been so for at least a day, or a Hurricane. When a system is developing this close to land and this quickly, GFDL often never gets the chance to lock onto it.

GFDL is based on the AVN run from 6 hours before the GFDL comes out (as I recall) combined with biasing information to allow it to lock onto the current storm center. Becuase of this, fast developing systems, like both Katrina was and Ophelia is, are hard for the GFDL to get a good understanding of.

Re: Tropical Storm Ophelia Forms off Florida East Coast

I don't buy into the fact that any model might weaken Ophelia, but to strengthen it. Possible hurricane strength by the 5PM advisory. Considering it is stronger now than predicted, the DV"s are higher now than they have ever been, so when the next RECON investigates, possibly, we might indeed have a much larger system, if it meanders over those warm gulf waters.

I agree. Ophelia has strengthened more and faster than anticipated. Since last night it has gone from 30-50 mph winds. I would expect 55 mph winds at the 2pm and then very close to if not hurr winds at the 5 pm with the new recon data. I hate to say this but, it would be better for everyone if this thing would just go ahead and come on in. Much less time to strengthen over the next few days. IMHO

LOL, it wont become a hurricane unless something dramatic happens in the next 6 hours. It still doesnt have a well defined center. Its a broad (but getting better organized) low with vortexs rotating still around it. Until we can find a tighter center....pressure under 990mb then it might become a hurricane.

Re: Tropical Storm Ophelia Forms off Florida East Coast

Well, with the steering currents the way they are right now it doesn't appear that Ophelia will be going anywhere anytime soon. She's drifted just north of Canaveral, and the winds here in Ormond Beach have shifted from NE to N. The waters where she's currently located are warm enough to warrant some strengthening, though she's still about 40mi east of the gulf stream. Like the NHC alluded to, it's going to be a waiting game of sorts to see how the trough and ridge interact, and how strong/organized Ophelia is when it occurs. Right now I'm preparing for some decent winds and rain. I've eyed a few tree limbs that look a bit suspect, and will be getting trimmed after work, weather permitted.

Um...in a word...NO! (in response to Force's question about anyone buying into it)

RC & Force - I hope your worst fears are just that...fears and not reality.

Time will tell...right now she's basically meandering out there so she's tricky to track/forecast/predict right now. I know NHC as well as others must be throwing their hands in air and rolling their eyes on this one. I for one am scratching my head. I do think however that she's getting her act together a touch quicker than originally anticipated.

My best guess (emphasis on guess) is this:

1.) She will be a hurricane come the end of the weekend. I'll stab at borderline CAT 1/2. (Conditions (at least for now, support this)

2.) I do not think she'll make it further north than 31/32N nor will she go east much past 75W before coming around again. (With lack of any real steering currents to speak of, I just don't see her getting that much further north before being forced eastward)

3.) I think if/when she makes it back around it'll be south of the Space Coast. (This ofcourse will depend upon that ridge...how strong, how south & east, etc.)

NewWatcher - I couldn't agree more....I'd gladly take one on chin from her now to prevent the threat she'll pose later.

The 06Z GFDL does make Ophelia a cat 2 hurricane once it moves into the Gulf of Mexico, which is the first time with this system that it takes it above tropical depression strength. The forecast track in the 06Z GFDL still has the system approaching an area by 126 hours that REALLY does not need another one of these right now.

Re: !

I hope so too. I don't want this thing getting strong.

----

Thunderbird - I just saw that. GFDL Nate on PSU is showing Ophelia instead...while Ophelia is blank. I wish PSU would fix this problem . I find it hard to see how Ophelia will strengthen while overland like the GFDL is forcasting.

Rabbit - GFS is also looping the system. With three global models doing it...and all three reliable models...I think the looping is likely. The question is:

- How close to shore will it be when the looping starts?
- How far south with the looping push it?
- How will the ridge effect the system's strength?

If the system is nearer shore when the looping starts, interaction with shore will weaken the system.

If the system is pushed less southward during the loop (the ridge weakens or doesn't move as fast to the south as GFS is showing), than it will be over land for an extended period of time, probably enough to dissipate it.

If the ridge brings shear over the storm, it doesn't matter how strong Ophelia is, it will weaken. That is what the NHC is thinking now. With a weakening, sheared storm hitting land, the system could mostly dissipate before reaching the gulf.

Let us hope that any one of these cases is true...and Ophelia never makes it to the GoM.

Tropical systems develop from lower level lows. For one to develop from an upper level low, that upper level low first has to spawn a lower level low. This is why the chances are low - such spawning isn't common except on very strong upper level systems, and even then it is rare.

Here's my thoughts.

Looking at the Water Vapor image:
http://www.intellicast.com/Local/USNatio...mp;prodnav=none

I don't see anything in the United States that would push Ophelia out to sea.

I do see a ridge of high pressure building to the north of the storm, although it is not a very strong ridge.

Based on that, Ophelia will turn slowly to the west in the next 24 hrs, strenghten to a strong cat 1 and come in somewhere between Daytona & Jacksonville, and move slowly across the state, following the bottom of the high pressure.

Let me know your thoughts.

What if?

Whereas Katrina didn't lose much intensity because she went over the Everglades, Ophelia would likely come into "proper" Florida terrain. Yes, many storms that hit FL restrengthen in the gulf, but at least as many (if not more) make landfall in FL and never exit until they are spat back out into the Atlantic - and farther up the coast.

When there is low confidence in the path, there's no reason to discuss if she hits the GOM - she hasn't made any indication of hitting land yet. Look at the extrap - to become a GOM event, she'd have to go W or SW right now - ain't gonna happen (we hope)

So, just because a model says this, and another says that, there are always situations where storms never behave like they are modeled to do.

Re: Tropical Storm Ophelia Forms off Florida East Coast

I'm waiting for the 12Z GFDL (about 4 hours away...plus however long it takes to get published...). It should be much more accurate for this storm. I believe the AVN model that the GFDL uses as a spawn this time will be the first AVN run seeded after Ophelia became a TS. This will make the GFDL more reliable.

As for a southward jog...don't count it out. This thing is moving so slowly it could go any direction.

As for Melbourne radar, it is starting to form the eastern edge of a central circulation now. This thing looks stronger than a TS on radar. It looks to be trying to form an eye. That normally isn't seen until strong cat 2. I don't think it is anywhere near that strong, but it says to me that the storm is more organized than we thought.

Re: What if?

Hey Rasvar, what (where) is the path across Florida JB is taking? Across Daytona, the cape, Ft. Pierce. Is he going with a loop or straight across? Seems that the center of circulation isn't moving much, but shear seems to be increasing again from the east. Wonder if the shear will increase and disrupt the system. I personally don't see this system cutting across across Florida south of 28N. I've never seen that happen since I've been here. Then again there were no hurricanes til '95

Looked at a couple different images/maps, and the "center" appears to be just north of the Volusia/Brevard county line. I would say somewhere in between Shiloh and Oak Hill, and off the coast a good number of miles, though on radar it does seem to have drifted west a bit. Still looking disorganized, with a lot of rain/squalls sort of floating off to the east.

Re: Tropical Storm Ophelia Forms off Florida East Coast

The Force......plz give out reasons why you feel Ophelia will do what you think. For 1 its not going to be a hurricane very soon, also Katrina was forecasted to move that SW direction,,,they just didnt know where it would turn that way to cross florida. We all like to hear what others think but we need reasons, links to models that show it, WaterVapor ideas seeing where it will go that way, etc....
This is actually for anyone as we dont need to to alarm people after what katrina did. Many are really scared. For now most models agree Ophelia will be a slow mover. Most 12z want to take her out to sea then curve her back somewhat near 75W and 31N by the weekend. Right now it looks like in the near term she will move closer to Daytona giving them gusty TS force winds. She will move closer due to the ridge over Nate moving away and ridging to her NNE ahead of the trough over the great lakes region. She should then be push by this trough away from Florida but we are not sure of this as of yet. The troughs energy should be taken NE by the weekend ( via most global models) as ridging builds in off the east coast early next week. If she is around 75W by Saturday still then she will probably feel this ridge and move back towards the states from Florida-Carolinas. For the near term its a wait and see.

Re: What if?

OK, I got it...thanks. So they don't see a loop involved, just a slow trek across north-central Florida. Odd path. The 12Z GFS just keeps her off the Florida coast then NE, then east , then stall again. The posisitive side of this is that this inhibits other storms from forming during this time (peak) period. Basically its buying time while just meandering these systems. Not a progresive (East to west) pattern.

Re: Tropical Storm Ophelia Forms off Florida East Coast

The apparent eye on the radar is pretty small and it wouldn't be surprising to see it break down at some point. The storm is obviously developing an inner core, though.

The 12Z GFS basically does not move the system at all for 48 hours, then begins to move it out to sea, but then slowly loops it back beginning at about 108 hours and finally brushes it up against Cape Hatteras at about 252 hours. That is just one model solution of many, but the bottom line seems to be that this could be around for awhile and be a pain to forecast.

WINTER PARK, Fla. -- In Orange County, Tropical Storm Ophelia's outer bands brought heavy rains that already collapsed a roof on a building at the corner of Fairbanks and Orange in Winter Park.

The Department of Transportation blocked off a lane on Fairbanks due to the collapse. Engineers were concerned the wall might collapse and debris could fall on the road. People in the building next-door were also worried the damaged building could affect their businesses, as well.

This system is no Katrina which had a very persistent and vigorous vortex all the way across under hostile conditions (TD 10/dissapated; TD 12/Katrina). This one is very much an infant by that comparison.
BUT the radar presentation shows an improving structure all the time...the center is now ringed with convection and shower activity is increasing on the east and southeast side. It seems to want to tap into the GOM side with a feeder band across Florida. In General this is a strengthening system...

Re: Tropical Storm Ophelia Forms off Florida East Coast

I referred to it as the "apparent" eye because I was not willing to describe it as a true eye. I'm not sure that there really is a scientific definition of an "eye", but weaker systems will have an eye-like feature on radar before they develop an eye that is visible from satellite imagery. Eyes (i.e. a relatively calm region at the center of the storm) don't spontaneously form when the system becomes a hurricane.

Re: Tropical Storm Ophelia Forms off Florida East Coast

Here you go Maddog: This was from Clark;
MissBecky -- the BAM series of models only take into account the steering flow and the Beta drift (related to Coriolis) of the storm. That's pretty much it, making them somewhat limited. The BAMM takes into account the middle levels as those steering the storm, the BAMD most of the atmospheric, and the BAMS (often not used) just the low levels.


pcola
(Storm Tracker)
Wed Sep 07 2005 07:49 PM
Re: Tropical Storm Ophelia Forms off Florida East Coast

I also found this explanation:The BAM-series models take the GFS analysis & forecasts and computer trajectories from the storm's initial position out to 120hr. The BAMS uses the 850-700mb layer, the BAMM 850-400mb, and BAMD the 850-200mb layer, with a small correction for the Beta effect (due to Coriolis; generally <2kt in forward motion towards the northwest). Note that the GFS has been consistent in decoupling the low-level and upper-level circulations of Franklin since its inception, taking the surface features to the north and east while meandering the upper-level features back to the west and southwest.

The two BAM-series models we've been seeing are the BAMM and BAMD, neither of which include the lowest levels to any large degree in their forecasts. Thus, their forecasts are largely going to be a representation of what the GFS views as the mid & upper-level steering pattern. Given what I noted above, it's not too much of a surprise to see them steer the storm more towards the west and towards land. This suggests that the GFS has either too strong a ridge, too weak a shortwave trough, or some combination thereof. No matter the forecast, the GFS solution is a rather dubious one for Franklin (unless you believe the storm will become sheared apart and fizzle out through time, which wouldn't be a bad thing necessarily), making the BAMD and BAMM solutions rather dubious at best themselves.

You can't entirely discount all of the forecasts, but I'd rather go with a model that represents the storm better -- such as the NOGAPS or even our MM5 (which uses the GFS initial conditions to start the model, but diverges completely from there) -- when making a forecast. Both of those models -- and most of the others -- agree on taking it north and then northeast, with varying degrees of speed through time.

Joe Bastardi's forecast

I don't want to dredge up another JB vs. NHC discussion (I agree with each one at different times), but I find it intersting that he still thinks it'll cross Florida into the Gulf - especially since he lowered the path to the south. I have yet to see any model support for this nor anyone here discussing it. I wondered if anyone else had any thoughts on this. Of course, there's isn't really model support for anything at this point. I figure a north Florida hit or the loop that all the other models see.

Boy, I hope the latest GFDL doesn't come to fruition! YIKES!

Re: Tropical Storm Ophelia Forms off Florida East Coast

There has been a very intense flare-up of convection on the west-side of the system in the last hour or so. This will probably lead to some further intensification, though how much depends on how far the convection can wrap around the center. It may also lead to some wobbling of the center, though I suppose it already has been wobbling to begin with.

They dropped it because a TS warning means that Tropical Storm conditions are expected within 24 hours. Since it is meandering north, TS conditions are no longer expected within 24 hours, for areas south of Cocoa Beach.

They spelled out that anything can happen in their latest discussion, but they don't believe anything to mean any trend southward.

Re: Tropical Storm Ophelia Forms off Florida East Coast

The last model to suggest something like the Accuweather forecast was the 06Z GFDL (and it was an outlier). The 12Z GFDL was much further north and the other 12Z models forecasted some sort of cyclonic loop with no landfall anywhere.

The 18Z GFS actually takes Ophelia right out to sea (no loop back towards the coast) beginning in about 24 hours. It would be nice if that verifies.

You know it's not gonna happen, though. I wouldn't be surprised if we were still asking ourselves "Where the *** is Ophelia going to go?" next Tuesday.

Update: MLB radar now shows 3/4 of an eyewall forming... all it's missing is the east side ... and that is even starting to "fill in" if you will. We could have Hurricane Ophelia by sunrise, I think.

Re: Tropical Storm Ophelia Forms off Florida East Coast

I was checking out a few things, and noticed that over the last 15hrs Ophelia has drifted just a bit more north than west(1degN/.6degW). This might not seem very significant, but the further north she travels, the more of an impact the trough should have on her. Something to keep an eye on for sure, and it's interesting to see Mike Seidel of TWC broadcasting from a beach approach where I sometimes surf.

The 18Z GFDL drifts the storm slightly to the WSW through 36 hours, then drifts the storm NNE until about 72 hours, then has it take an abrupt left turn and head west to near Jacksonville at about 90 hours.

TS in Iceland

When I was a kid and my father was stationed in Keflavik (Iceland) we had a storm come up the first year we were there...1978.

I had totally forgotten the name, but remembered the storm being something strange. Dad reminded me that it was "Hope."

We had a crazy summer that year in Iceland...our midnight babeball games were sometimes played in 50 degree temps, and then a few nights later in snow.

Iceland was THE coolest place to be a kid, though. I was there 4-6th grade.

WX patterns were COMPLETELY whacked, though, since we had the Gulf Stream circling us.

Good times.

Volusia County schools are faced with the same delimna that everyone else on the East Coast is facing. Can you imagine having a bus load of kids injured because a wind gust blew the bus from the road?!?

Most of the EOC's in this area on "stand by" mode. We outfitted ours today and can activate within 45 minutes, but conditions in the area right now don't require any activation. Hopefully, we learned something from the aburp shift of Hurricane Charley last year. "Be ready and don't let your guard down."

Volusia County is opening one shelter tomorrow. It will be at the County Fair Grounds and will actually be three shelters in one - persons with special needs, general population and pet facilities. The west side of the County has been dealing with flooding for weeks and can not handle any more rain at all. A very strong squall just passed over my house about 1.5 miles west of the coast, heading for the west side of the County.

Pressure often drops in advance of a wind increase. In fact, the latest Vortex recon from about 8pm shows the pressure drop to 994mb and a FL wind drop to 42kt, down 8kt from the 5pm recon. I would expect a wind increase before the next recon based on the pressure falls.

HCW - Using Katrina doesn't help explain anything - she didn't do anything by the book. Katrina had a pressure fall and eyewall expansion at the same time at one point. That should not be possible under normal hurricane growth.

Re: Tropical Storm Ophelia Forms off Florida East Coast

Ok...let me see if I can explain

---

Pressure fall leads to a wind increase. This wind increase can be after the pressure fall by a couple of hours.

The alternative is the central wind field can expand. This would leave the wind speeds the same or lower with a pressure drop. It can indicate a growing storm.

As someone mentioned a good analogy, think of a figure skater pulling their arms in. They go faster. That's what happens when an eye contracts. Now a pressure fall is the equivilent of spinning faster without changing your arms. If you let your arms out, it can return you your old rotational (ie wind) speed, but it expands the area within which you see that wind.

Does that help?

The supplementary vortex message issued after the recon fix indicates a flight level wind of 54 knots in the SE quadrant. I believe the strongest winds were found in the SE quadrant by the last plane, too. Based on how the system is structured, that is not what you would expect, since the most intense convection is to the west.

As weather forecasting is still an inexact science, this not for profit weather discussion is not for use in lieu of official sources, is not for protection of life or property, is for educational purposes only and is subject to human error and acts of God, therefore no guarantee or warranty implied.

Once again sorry for the recent silence as I had been in the moving mode from Plant City to a newly purchased house in Lakeland since Sunday August 27th. Only now have I recovered from the ordeal.

At the 8:00 pm EDT NHC/TPC advisory T.S. Ophelia continues to be quasi-stationary. She has a sustained wind of 50 mph, is at position 28.8 deg. N 79.3 deg. W, with a minimum barometric pressure of 29.35" a slight fall since 5:00 pm EDT.

Looking at latest NWS Melbourne, FL NEXRAD radar as well as IR and WV satellite imagery, she continues to get better organized, with convection wrapping around the center of circulation. However she also continues to suffer from just enough southerly wind shear so that most convection is absent in the south and east quadrants. It appears that wind shear will increase with time so I doubt that she will reach CAT 1 hurricane strength in the near term. But as she is over very warm water anything is possible.

Where is she headed? Well quite simply it's totally impossible to accurately forecast a stationary tropical cyclone and as usual the models are quite useless. Eventually a mid latitude shortwave trough will swing by to the north and give Ophelia a tug to the N-NE. But how much of a tug will be determined by the strength and position of the trough. I think the trough will pull her N-NE but not pick her up and send her out to sea. Then we will see high pressure ridging develop to the north and that will swing her around in a clockwise looping motion and head back for the east coast of Central Florida as a CAT 1 hurricane, much like Jeanne. But once again this is no more than educated speculation at this time.

Hurricane Maria is only a threat to shipping and Hurricane Nate will brush Bermuda and then head for the shipping lanes too. There are several other tropical disturbances currently in the Cape Verde wave train and as usual will have to be monitored.

I've had no opportunity to comment on the horrific tragedy that unfolded in LA, MS and AL last week with Katrina. I had made a prediction of 10,000+ fatalities and it appears that it may come to fruition. Personally very soon I'm going to travel to AL and MS and hand out food, clothing and $$$ to victims. One very serious lesson that needs to be learned is that you can never depend on government to protect you and take care of you.

Has Ophelia started to be affected by the gulf stream and is it still as warm as it was when Katrina was getting her act together?
I had a dream several years back about a hurricane going in to Jacksonville and heading south through Tampa Bay. This was after Andrew and before Floyd that I dreamed this. In the dream politics was blamed for a great deal of death and destruction. I am not saying that any of this is going to happen, it is just a dream that stayed with me all these years. It looks like from some of the model plots that it is coming true and the politics could either be the current ones regarding Katrina or more for Florida. I am so hoping that my dream world is just composed of too much publicity and is totally bogus. On the other hand, if the experts that you trust start telling you to get out or to evacuate. Please do. I am not sure if the country could stand more death and destruction in this year.

It's interesting to hear that Volusia County is closing schools due to high winds, as we in Jacksonville ponder upcoming decisions. I'd hate to be in charge of the school board or anyone making decisions now. Ophelia is supposed to be thisclose off of our coast, it looks like you could swim out to it. I mean, how do plan for that? At 75 miles one little wobble is all it takes. I suspect we wouldn't know until the last minute if it's going to head closer.

Re: Tropical Storm Ophelia Forms off Florida East Coast

Well, the pressure going up is a good sign. If Ophelia has been sitting and spinning in the same area for almost an entire day, she has to be pulling some of the heat out of that water .... "upwelling" is the technical term for that, I believe. She cannot keep feeding on the same waters forever.
I just so Joe B. on FNC. He's okay sometimes, but I really hate the "everyone pat me on the back" stuff and then he said that Ophelia could go anywhere. DUH.

nothing much to add

ophelia isn't quite as strong as i'd guessed it would be, and isn't quite as far to the west either. shouldn't affect the idea of an anticyclonic loop off northeast florida over the weekend. i think it'll go further east than the official, but nothing nutty like the long eastward jaunt the gfs is advertising... it's over-recurvature bias has taken over again. i'm not very sure what will come back to the coast next week. it may still be an off-balance, modest tropical storm, or maybe it'll go jeanne on us under the ridge. the window for its return i'll leave between daytona and charleston.. the big empty quarter that strong hurricanes have generally avoided in the last century (although further back in time this was not the case).
don't see a whole lot going on elsewhere. nate and maria are going out.. nate is going wide of bermuda. wave in the central caribbean is now hard to identify, and shouldn't perk up for days. mess in the gulf is going to be onshore before it can do anything. the big/sharp upper trough that was near 50w has split, with an upper low moving westward near 55w. still pretty much guarantees it'll chop up waves coming in from the east... that big envelope wave near 40w looks to be first to go. the new wave off africa is low latitude and has little model support. lots of dry saharan air down there, keeping the deep tropics relatively stable for now. gfs shows it getting a little livelier late next week. will see.

Accuweather has not had a good track record recently. Only one (as far as I can tell) of the models suggest the possibility of going directly west into the gulf. I feel there is no support for their solution. Ophilia is in a col, kind of a dip between several high pressure areas with no real desire to move. Any movement will likely be sllightly north, maybe east, maybe a loop, but not likely directly west per Accuweather. Whatever happens will likely NOT be very fast.

Re: Tropical Storm Ophelia Uncertainty

I'm not discounting the accuweather idea.

Looking at the water vapor loop, there is a ridge that is from the Atlantic Ocean to Texas. It starts curving NE just north and east of where Ophelia is located.

The NHC and the models called for a drift in a north direction (NNW, NW, NE, NNE have been mentioned at one time or another) However, the storm has not drifted north at all. In fact, it is SW of it's position (barely) of 24 hrs ago.

Unless it starts drifting or moving north, at least 75-100 miles north, it will miss the push to the NE and then will be pushed into FLorida. And this morning, it looks to be drifting in a southerly direction.

I'm not an expert, but just my thoughts. I would agree with Accuweather on this one.

Re: Tropical Storm Ophelia Uncertainty

Ophelia looks a little ill on satellite pictures this morning, though the radar appearance is somewhat more symmetrical. It appears the shear may have lessened somewhat, but there is some very dry air just to the north of the system.

I know, it's nuts. Funny thing is when I got up and checked this a.m. she actually looks closer to me then when I went to bed. Go figure. Crazy storm. Warnings have been lifted and the weather is far worse now then when we had them...lol!




Looking at the water vapor and IR loops, it looks like the storm has weakened substantially in the last several hours, with the "secondary ball" actually looking better than the primary one. Yet the winds have increased to 60 and the pressure stablized a < 990 (989 currently although it got down to 985 overnight). Dry air intruding? Looks like a lot of dry air north of the storm on the water vapor loop. Maybe it'll fizzle out after all.

ETA: yeah, Thunder... the radar actually looks MUCH BETTER but the satellite WORSE.... what is it with this storm???

Re: Tropical Storm Ophelia Uncertainty

With tropical weather, no one in their right mind will totally discount any possibility and given the proximity of the storm to the east coast, it is prudent to make plans for the worst case scenerio. However, one also needs to plan for what is most likely. The closeness of the storm to the coast amplifies all of the effects of even small wobbles so it is likely that East Central Florida *will* see significant effects from Ophilia. I just don't feel the Accuweather solution is very llikely, not impossible, just unlikely. More likely is continued wobbles alternately bringing the center close to shore and then away from shore and covering N and S movement as well. Overall, the track will probably tend N over the next day or so, with wobbles back to the SW, SE, NE adnausium. For the sake of those in the gulf area, I hope this is the solution, not the one proposed by Accuweather..

Re: Tropical Storm Ophelia Uncertainty

This is for anyone. I wonder how much upwelling can occur with a developing storm like this, I guess the Gulf Stream will just keep pumping warm water under it.

Is the "EYE" Forming?

First look at the radar Presentation:
http://www.srh.noaa.gov/radar/loop/DS.p19r0/si.kmlb.shtml

Sure looks like she is filling in the blanks.
Then look at the last couple of frames of the visible loop:

What do you think

Re: Tropical Storm Ophelia Uncertainty

I am concerned about the area over the Bay of Campeche. Any chance this could organize and if so were would it go?
Also, is it my imagination, or is Ophelia looking ragged?

Re: Tropical Storm Ophelia Uncertainty

Ophelia is more ragged right now, you can tell by looking at water vapor or IR satellite loops that it flared up overnight and died down this morning, but seems to be rebuilding again now. In the meantime the center has gotten more ragged and some dry air in the east and west sections of the center have affected it. I'm hoping this will hold off strengthening today. It's still too close to comfort for me, and at this point wobbles can mean a lot.

What about the area in the Bay of Campeche? What are the chances that could form into something tropical?

I haven't had the chance to look at that, someone else might know more. A quick glance seems like it would take a few days for anything to happen there. I'm not a met so please don't take my word for things.

As to the Bay of Campeche, local weather here in Pcola says it could develope but it will be slowly and they expect it to head into Mexico, and they are not considering it a threat

BOC Activity

per accuweather, a tropical wave along 94 west south of 21 north has a broad area of low pressure over the Bay of Campeche. A large upper-level low over the western Gulf is venting the southern Gulf and central Gulf causing enhanced clouds and thunderstorms. As the upper-level low moves southwestward, the area of low pressure in the southern Bay of Campeche might become an organized tropical system in a couple of days.

Re: Tropical Storm Ophelia Uncertainty

What can any of us say about these forcast tracs? Nothing unless we know the science that goes into those models, and I certainly don't.
But I do know that the WV suggests the ridge is pushing hard toward the SE coast, and that coupled with the relative weakness of the system will not allow for much movement, more or less northward movement..
As for the storm's appearance...it is not able to grab much energy producing moisture from its SE quardrant as these things want to do as there is none there..it has to pull what it has in from the SW over the GOM, and that is inhibited by that large ULL...so I don't see much increase in intensity today, although some convective pockets are showing up on the visible.
It is possible if the storm does not ramp up a bit it could actually be pushed south a bit by what I see in the ridge pushing down to the SE today...that of course is very unscientific speculation...but we'll see I guess!

Am I crazy, or does the MLB radar (@ 1341Z) show convection wrapping around what seems to be a center located a bit more to the south (like due E of MLB)?

Could be. I think there has been a little jog to the S/SW, but who knows with this thing, and I am not an expert.

Either way, we both need to keep an eye on this thing.

Re: Tropical Storm Ophelia Uncertainty

I've been watching the I.R. loop for a little while, and the "piece" off to the NE looks like it's trying to pull off/away from Ophelia. There have been flare-ups here and there, but she's still not looking very organized.

Re: BOC Activity

Thanks for the information. Since it looks like it might head into Mexico if something develops then Texas won't need to worry.
I have been watching it, however, and it does look like a possibility it could develop into something.

Re: Tropical Storm Ophelia Uncertainty

Looks like another sub-vortex has spun up inside the broad center of the storm, based on the radar. There isn't as much shear evident as there was yesterday, so the storm may have a better chance to intensify more with each new burst of convection (like the one that is flaring up now).

There are also some 64+ knot wind speeds at beam height showing up on the radial velocity from the Melbourne radar in the last couple of frames. If that persists, the wind speeds with the system will likely have to be taken up a notch in the next advisory.

Ophelia looks to be going through a little spurt of trying to better organize. Still looks like it is going nowhere. Due east of the Cape right now.

Re: Tropical Storm Ophelia Uncertainty

We should really watch the pressure to see if there is true intensification...much of the wind speed could be influenced by a deepening gradient between the high and the cyclone without actual lowering of the pressure..by all stretches at 989mb, it could already be at 74kt but it isn't because it is struggling to build convection in relatively dry air.
I think the pulling of the NE quardrant away by the easterlies is very significant not only in the loss of energy, but could signal the actualization of the logic of the Accuweather forecast from yesterday which suggested that the llc would split off and move west..
that can still happen...much of the model guidance I can see for the loop was based on more northward movement by now which has not happened...
As I see it this vortex was caused by an"eddy' in the atmosphere, and that eddy is still stuck..the longer it does not move the more chance for a westward solution in my opinion...

Re: Tropical Storm Ophelia Uncertainty

Per 11am all the same as before no movement and same winds just a update of 5am


The future track has a NE movement per 5 days. after 3 days it starts the loop.

Re: Tropical Storm Ophelia Uncertainty


Question for the prognosticators: The five day forecast track has Ophelia geting a little northeast and then starting a loop back to the south, not all that far from where she is now. After that period (and I realize the track itself is highly uncertain), what is the long-term thinking? I confess an inability to read the maps for the NW and Midwest U.S. so I don't know whether to expect a ridge to build in and force it back to the west or for a front to come through, pick her up, and sail her off to the deep Atlantic. Thoughts on that?

Also, I understand that SSTs go down in the wake of big storms and affect storms coming shortly after them. Is there any chance that stationary churning by Ophelia will lower the SSTs under her? Its a middling T.S. now -- is that enough to impact the SSTs and, also is the flow of the Gulf Stream going to keep the SSTs warm just because of where she has parked?

Thanks folks.

Re: Tropical Storm Ophelia Uncertainty

5 day forcasts from the NHC have large errors anything beyound 5 days is a GUESS you may not agree with me some of you but it is.

There is noway beyound a guess since the NHC does not even go past that since systems change each day so to say in 7 days it will go here or there is just a guess.


My guess past 5 days? ....Watch it see what it does that is my guess.
