T.S. Jose Forms in Bay of Campeche, Several Other Waves being Watched
      #48520 - Mon Aug 22 2005 05:44 AM

5:30pm Update
Recon reports indicate that T.S. Jose has formed from TD 11 in the Gulf of Mexico, with sustained winds of 50mph and sea level pressure of 1002mb. Landfall is expected sometime early tomorrow as a moderate tropical storm.

Noon Update
Tropical Depression 11 has formed in the Gulf of Mexico, it is expected to move westward into Mexico as a tropical storm.

Original Update
There is currently nothing being tracked as a named storm or depression, but several active waves being watched right now.

The one closest to being classified is perhaps the wave in the Bay of Campeche, this was hovering over the Yucatan for the last few days and now has emerged into the Bay of Campeche looking rather good for development.

This would be short lived however, as it would likely move on into Mexico before becoming too much.



Moving east is the wave over Cuba, basically still the remnants of Tropical Depression 10, no development is expected but it may be able to slide into the Gulf, and if so will need to be watched. It could create some rain for parts of Southern Florida as well.

Out in the central Atlantic an African wave has persisted a bit and may become a depression in a few days if it continues to hold together. If it does, the most likely scenario is otu to sea for it, but it's worth watching.

Beyond that another healthy wave off Africa is there, and we can watch to see if that persists over the next few days as well.

Nothing overly concerning right now, and for late August, this is great news.

NRL now officially has the wave near the Bay of Campeche as 98L.

The sattelite IR presentation of the system also looks impressive for a wave, and with the an air force reserve reconisance aircraft expected to investigate it today, clearly NHC is concerned about its development.

-------------

In reference to the wave south of Florida, while I realize that the CMC tends to over-strengthen systems in the gulf, it still makes you worry about what that wave is going to do!
http://bricker.met.psu.edu/~arnottj/cgi-...;hour=Animation

In comparison the NOGAPS isn't really picking up on that wave and the GFS is sending it into Florida's east coast before it has a chance to strengthen. I think its track will have great influence on what happens to it.

-----------

The first GFDL run on 97L is out...and it dissipates the wave in about 24 hours. I find that highly suspect since almost every other model strengthens the wave, albiet slowly. CMC is still showing a strong system taking a northerly curvature while NOGAPS is keeping it weaker and more westerly.

See that Random? And you said you didn't see anything down there on Saturday . I didn't either except to say it was something I was watching. When they have the look or the color [tm - Bobbi], you gotta consider them in this type of season where the bulk of the SSTA's in the Atlantic Basin are running high. As for the Canadian, it was doing basically the same thing yesterday. The 00Z European doesn't make as big of a deal with it but does form something off the W Coast of FL and moves it into SC LA. Almost all of the globals that show anything show genesis and intensification near or over Florida. If it's the west coast or SW coast, the FL posters are on the wet side and should see some rainfall at a minimum. Looks like we're about to get back into tracking mode.

Tough call as to 98L on whether or not it can make it beyond a STDS (not that kind of STDS) to a depression or minimal tropical storm. What we've seen with most of the 3 storms that impacted the E coast of Mexico this year has been a strengthening/tightening mode at landfall. I woudln't be surprised if this turns out to be Jose any more than I'd be surprised if it stayed a blob of thurderstorms. As I said the other day, it's something to watch.

Should be an interesting week.

Steve: On satuday I didn't see anything

-----------------

As per the 8 am EST TWD update:

Both the Bay of Campeche and the south-of-Florida waves have no associated deep convection. However, the south-of-Florida wave has "LOW LEVEL CYCLONIC TURNING" observed.

The central-Atlantic wave is no longer mentioned on the TWD.

The east-Atlantic wave: "THE CONVECTIVE INTENSITY IS NOT AS INTENSE AS EARLIER" but they are still predicting cyclonic development with it. Could be it's at a diurnal weak point?

Random, can you give us some sort of present location of where the low level turning is located in the area south of FL? And if you know, give some kind of direction and speed because I don't see anything other than a cloud mass with no apparent organizatiuon to it as of 8:15am. Thanks, J.C.

the rundown this morning:
new 98L will get reconned this afternoon and will probably be classified. the core of the feature has moved offshore now; it should have enough time to get organized. joe b says landfall late tomorrow near tuxpan as a tropical storm.. see no problem with that.
97L is over marginal SSTs and is entraining some dry air. this should act to keep it broad and fairly weak through the next 36-48hrs. should only be minimal development in that time. after that it should slowly deepen. a recurvature corridor will be open for it if it's strong enough late in the week. if not, it'll have a shear zone/upper trough to break through like irene did a couple weeks ago.
xtd 10 is what concerns me the most this morning. the outflow pattern is shown to be very favorable around it by mid week, with the rising heights in the northeast and shortwave bypassing it to the north, low pressure is likely to develop in this area. models tracking it either just east of florida, over florida, or into the eastern gulf. i was thinking about what jb would have to say over the weekend.. this morning his ideas all panned out like i'd expected. development out of this system will be trouble, and the pattern is evolving so as to facilitate that.
the wave behind 97L is shown by most globals to keep a low trajectory.. nao is positive now and should favor zonal ridging. in the two week period that wave will likely be responsible for what we're talking about then.

H.F., If this thing does track to Fl do you have any idea as to when and what we may be talking about? Do you think it will be just a rain maker or is it likely to be something worse?

that is 2 models out of how many? CMC has done nothing to impress me so far this year.

Personally i dont think models get a good grip on anything till they become something and as of right now its a open wave.
out of the FSU plots.. it's 3 out of 4 have a closed low. the other one sees 'something' open. euro and NAM both show something developing. GFDL hasn't been initialized on it. all of them have something moving over or just east of florida this week. -HF

watching low cloud motions near the se bahamas... there's a low forming down there.
first ssd out on 98L.. it's at 1.5. the system has a CDO, so it should strengthen up to landfall.
97L probably won't do a whole lot until it gets near 40-45w.

Looks like the Westerly flow is still with us.
XTD-10 could drop some rain on S.FLorida and then get into the Gulf and head WNW...
Something to watch for the next few days. It's very slow moving.

HF definitely a twist to the system ... but I can't discern a LLC, a mid level rotation but nothing at the surface that I can pinpoint, unless its really broad in scope, which is also possible as its in the developing stage... shear still attacking it from the UUL above it however on the northern quad and ahead of it... however, I do like the rotation it is now presenting... which is a good start...

random morning [Re: Steveunplugged]
      #48540 - Mon Aug 22 2005 11:06 AM

Decided to check in around here to see what people were saying on the African Wave (that doesn't look all that good anymore) and the remnants of TD10.

Beginning to wonder should it develop if the NHC will go with 10 or 11 as they have stopped using the TD10 designation in favor of "showers"

One model has it developing just past FL and turning it into a hurricane. One sees the front and I suppose is more interested in the front and staring at the front...doesn't do much with the wave. Others have it meandering west.. creating weather but not much else.

Have to stay with the thought that if something persists as an entity this long it bears watching.. begs you to watch so we may as well watch. Warm water yes (accounts for color) but unfavorable winds... makes it hard to define a center. Might hug the Old Bahama Passage all the way into the Straits if it really is trying to develop somewhere down the road. Either way.. it's more intriquing this morning than anything else.

Top half of the African Wave is dry.. missing in action. There's dust in that wave and mostly along the top. Until the Dust Monster is dealt with... waves won't develop until they are much further west.

Lastly...Looking at the WV imagery from high up in the sky..that is one of the most bizzare "highs" I have ever seen and not going to be that easy to get a storm across the Atlantic until that changes.

http://www.nrlmry.navy.mil/sat-bin/displ...RENT=LATEST.jpg

Thanks... random indeed.. didn't plan to check in here but randomly I suddenly did.

Wierd set up going on right now for all the predictions of a busy second half of the season to verify. Suppose size doesn't matter and if you have a bunch of little storms forming fast in BOC or close in to Florida and going out to sea..the numbers are still there.

Lo and behold, it reformed out over water. That's two of three I've been fooled on this year...not so fun when you're trying to predict these for a living! Thankfully it'll be a short-lived storm, but it's yet another to add to the annals of an active 2005. If Jose forms today, we'll tie 1995 (which had 3 storms form on August 22nd) for the record pace. Figure that's a good bet.

97L doesn't look as impressive convective-wise this morning, but is still well-organized overall. Expect the convection to make a comeback tonight and development to proceed from there. Wave behind it is getting some looks from the models now as well -- it's as well-organized as 97L was leaving the coast. Here comes the activity, more likely than not -- and like it or not.

This season has a very good chance of going into November,given the very warm water temps.It is only August 22nd,and now there are 3 systems to watch.But,don't you think it would be great if there were no more storms?But,THAT will never happen.

Maybe TD10 part deux??? I hope it's called only a rainmaker and nothing more!

Clark - I feel for you. My cousin is a met. in WPB FL...says this year has been a real head scratcher. I don't hope for more storms but if there are, I hope for your sake (and all of ours) that they're more predictable.

Can someone post a link to 97L stats...can't find anywhere. Want to know rate of foward speed so as to know what longitude it'll be near in 36-48hrs.

NHC predicted the number of storms for the season but did not claim there would be the exact number they predicted. Also, the predictions were based on certain criteria and also a very active July. Just because August has not been as active as July doesn't mean September or October won't be. We won't know exactly what will happen until it happens. Humans can only predict and although technology has come a long way there is still a lot we don't know about the weather. Anyway, the hurricanes are interesting to follow each year simply because the formation of these storms is fascinating to watch. And whether there are Category 4 storms out there or tropical storms they are still storms. And I will tell you from having lived through Allison a tropical storm can wreak just as much havoc as a hurricane at times.

Looks like now the 06Z GFS has latched onto a closed low developing in the central Bahamas and drifting west to the gold coast, across S FL, and then further developing in the SE GOM. That makes it nearly unanimous among the global models (includes 00Z Euro) in developing a depression or TS and slowly drfting it west into the GOM. If you believe the GFS, it will take this low 72 hours to go from offshore Ft Laud to offshore Ft Meyers in the Thur-Sun time frame. Wow, looks like a major rain event if nothing else.

What a BUST August has turned into, IMO there is NOWAY we will
reach the number of named storms that NHC or G.G. has claimed
there will be...This whole season has been nothing but hype. Really ticks me off.




first off, I dont think the people in Cancun, Pensacola, Cuba, or south of Brownsville will call it "nothing but hype"
second, EVERY YEAR we have a quiet period in August--in 1995 we had 19 storms; we had the seventh on August 10th and didnt have another for 11 days; in 1999 we had 12 storms, with the first on June 11 and the SECOND on August 19; 1984 we had 12 storms, with the first NOT EVEN FORMING until August 29!

Also, the peak is not until SEPTEMBER, and the last several years, the majority of activity has been AFTER AUGUST: 1998 we had 9 of the 14 after August, 1999 we had 7 of 12 after August, in 2000 we had 10 after August; 2001 we had 7 of AFTER SEPTEMBER, and if you remember last year we had 8 by now, with 7 more to follow after August. And last year had a long period of nothing mid-Oct to late Nov.

I am holding to my prediction of 16, and i think it is still very likely to reach 21 storms. If we have one more storm by 2pm tomorrow, we will be ahead of EVERY YEAR PRIOR!


now, as for the systems out there: TD11 will likely become a TS later tonight; XTD10/Trop Wave will not develop, upper winds are too strong; and 97L will probably not develop at all until the end of the week if ever--there is still too much dry air in the circulation, and the convection has weakened quite alot since yesterday.

Well..that storm down near Mexico is going to hit land and will probably get a name. Beautiful to watch how it began spinning.

As for spinning.. hard to believe but off the N Coast of Haiti...something seems to be trying to spin.. or is twisting for sure... hard to believe but give it a look.

Ran your model loop here on lunch break.. a small storm if anything but plausible and could happen if the showers stay far south enough to not get caught up in that frontal boundary. Her weakness may save her..

>>XTD10/Trop Wave will not develop, upper winds are too strong;

You should always put a caveat when dealing with the tropics or else use proclimations with universal modifiers with caution (not, never, always, definitely, etc.). The Upper Low to the NW of the wave energy and leftover energy from TD 10 will continue to move west to wsw over time which is what I think the globals are waiting for to develop the surface energy. If it does cut WSW or even SW, then the pattern reversal will, by nature, mean that upper level high pressure will replace the upper level low pressure that was formerly in that general area.

Bottom line, no way would I say "WILL DEVELOP" because upper level winds will be light in the next couple of days. I'm only going to say watch and see.

maybe 73w 22n? ish
i think it's becoming more than a wave now....
there is shear on northern side....but it might be to its favor.
South Florida is in for some RAIN next week...............

If you believe the GFS, it will take this low 72 hours to go from offshore Ft Laud to offshore Ft Meyers in the Thur-Sun time frame. Wow, looks like a major rain event if nothing else.






We could certainly use the rain here on the west coast. It's been a *very* hot and dry August. I've been watching the model runs on this one, and I do think the CMC is too bullish on development once the wave hits the GOM. However, as more and more models begin to show the same thing, it's becoming harder to ignore them. Here's hoping nothing major comes of the wave, but I will say the rain and cooler temperatures will certainly be welcome.

No such thing as cooling down in FL this time of year, lol. I wish there was.
Rain we can do with. We had so much in July over here in Daytona we almost
drowned and in August just about nothing.
Anyway I am not liking the model concensus concerning XTD10.
CMC GFS and NOGAPS all show this evolving and moving right over FL
The FSU shows it off the SE coast near GA
UKM shows it in the middle of the gulf. With them all agreeing on SOMETHING
and FL being close, definately bears watching

other off the wall stuff [Re: MissBecky]
      #48564 - Mon Aug 22 2005 01:12 PM

take a look off NE coast. in the warm sector east of the advancing front, that old frontal low that was off hatteras the other day has acquired a convective core. it's being baroclinically forced and will leave support SSTs within hours (currently near 39/62).. if it was a few hundred miles to the south it would probably be a short lived fish spinner. maybe it's evolution is indicative of the pattern we're entering.
noticed the low level flow with the wave entering the caribbean is backing as well... just scattered convection, though, so don't think a low pressure will form.
some years the fourth week of august just goes nuts...

Pam, on board with u with the consensus of models forming a closed circulation. I think the big story with this feature may be its very slow movement. None of the models are really deepening the low except for the CMC. My geuss, & only one, is that we'll get a tropical depression or weak trop storm forming before it moves across the peninsula to the GOM. That being said, some of our highest rainfall amounts are associated with weak systems so this could potentially be a 5-10 incher if it really moves at a crawl as the models show. I did see the latest VIS SAT - looks to be a broad rotation now in the SE Bahamas.

From the NWS in Miami

ADVANCING TROPICAL WAVE PROMISES A MUCH MORE ACTIVE WEATHER REGIME OVER SOUTH FLORIDA LATER THIS WEEK. 06Z GFS SHOWS CONTINUED VERY SLOW MOVEMENT WHICH COULD MEAN VERY HEAVY RAINFALL LATE THIS WEEK.
OF COURSE...IT WILL BE CLOSELY WATCHED FOR ANY FURTHER DEVELOPMENT
AS WELL.
BY LATE IN THE WEEK THE HIGH BEHIND THIS FRONTAL TROUGH SHOULD HELP REBUILD AN ATLANTIC SURFACE RIDGE BACK TOWARD THE PENINSULA.
SO TROPICAL WAVE IMPACT MAINLY TUESDAY FOLLOWED BY WEAK SURFACE
PATTERN AND PLENTY OF MOISTURE WITH AFTERNOON AND EVENING CONVECTION THE REMAINDER OF THE WEEK.

Also this from the NHC

i just saw the vis zoom on the bahamas wave
interesting to see how Hispaniola is influencing the wind pattern--north of the island, there is a definate closed, if broad, rotation, at least in mid levels, but south of the island, the winds are all straight out of the east

i think this has a shot at development before the end of the week

Of course, I'm good at seeing phantoms, but it looks close to closing off a SFC low around 21N 72W or so, it's still disorganized but looking at the msfc visible loop in the area, you can see a sw to NE turning to N then Turning to NW then W... windflow at the surface I don't think there's a south wind on the west side of the wave. but it's starting to look a little more viable....

i think it will be reclassified (as TD 10 or maybe they'll just call it 12) tomorrow. it's slowly , slowly spinning up... looks to be focusing near the convective burst that has been going off all morning around great inagua (the slightly larger island in the SE bahamas). there's a shortwave ridge moving in from the east which should start to ventilate the area tomorrow.. today it's in a weak sheared environment thanks to that small upper low sliding by to the north. if this thing develops.. and it looks to be.. it's a big ticket item. most of the globals have it crossing southern florida into the gulf late in the week.
td 11 may or may not get bumped up to jose. the deep layer flow caught it as it developed and it's moving faster than the globals were showing (they tend to hang things up in the rim of the BOC anyway). should move onshore tonight, not tomorrow night, like the official says. recon will probably find winds near t.s. force. NHC likes to play these conservative. they probably won't upgrade it unless it makes a convincing case.
97L looks about like it has for the last 36 hrs or so. the center is near 16/33 and moving over marginal SSTs/though a marginal environment; some of the dynamic guidance has it making a pretty dramatic recurvature near 50w at the end of the week. i'm not sold on that evolution quite yet.. with nao positive there should be a tendency for stair-stepping storms that feel troughs and miss them.. unless they're fairly strong.
that model-seen coastal low that peels out from the carolina coast as the current shortwave over tennessee moves off.. i'm more convinced it will exist than some of the other hybrid storms models have been waffling over so far this season. i do think it will be hybrid, though.. e.g. not a classified tropical system. globals were earlier trying to deepen it and recurve the old TD 10 energy with it.. with the nao state it will probably just deepen and go.. and let the ridge push back in behind it a little.

Am I blind? How come I just do not see the closed circulation...anywhere? Don't get me wrong, I can see that it's obviously trying to get it's act together...but I just do not see the CCOC.

UGH! Anyone here remember Irene (Oct.99) ? SE FL..we got hammered with the rain (and that moved much quicker than the anticipated system.) My street was blocked off by cops for an entire week until the water receed to a safe level.

What's the timeline for potential arrival on this thing? I gotta be in Orlando from tomorrow until Fri. for a convention.

I know end of week. Are we talking Thurs/Fri or Sat/Sun??

Thank you, Hank Frank.

But I am interested in knowing if XTD10 will be renamed TD10 or would it more likely be given a new ID as TD12 as a 'home grown' system.?

Which way would the NHC lean towards?

complaints? [Re: native]
      #48572 - Mon Aug 22 2005 03:13 PM

i went and read the graveyarded stuff this morning. i'm not sure it should have been deleted... because even though i'd call the comments misguided they didn't really break any rules. gotta wonder why someone thinks tropical systems don't count because they're weak and hit mexico, though. we get a couple weeks off the insane pace we had in july and a bunch of people start shrieking about the active season being a bust. mind we've had that every year i've been here in some fashion or another (was really funny hearing people talking about a slow 2004 in late july.. august shut them up real quick). last november when i put my season #s at 17/11/5 i was thinking i'd probably miss high... glad i didn't give in to the consensus and go lower when the adjustments were made in may (EVERYONE was below me).. just kept 'em there. i dunno.. maybe i've always thought that forecasting wasn't about vacillating with the crowd, or trend of the week; if you're right, you're right.. if you're wrong you're wrong. it's looked like i'll miss low ever since mid july. name me a year in the last ten where we've had fewer than eight named storms after august 21. just 1997. i don't see that el nino, hombres.

Those graphics are beginning to remind me of Irene (1999).
I think that the models are having difficulty in defining the strength and direction of the remanants of TD10-let alone if it will be renamed TD10 or given the latest number on the docket.

Looks like model hash to me....wait until they have LLCC to initialize on....

Agree with you 100% HF on all aspects of your last post (about previous seasons and sticking to your guns).

Train is leaving the station, it's about to get REAL interesting....lot of rain for S Fl, at the least, it seems.

PS--1935 CAT V was a tropical storm in the Bahamas 24 hours before landfall. I am NOT saying that will happen this time...just that 'anything' is possible.

I'm curious why I keep hearing that it may cross Florida. I think JB said this a.m. it may be off the coast of the Cape later in the week. All the models have it going under Florida. Are the models not accurate at this stage of the development??

There's just too much shear over the Bahamas/Hispaniola right now to get anything going. The circulation that is observed by some is not at the surface, since you can see the surface flow of the wave moving by. It's trying to get it's act together though, but the shear still remains brutal. Maybe conditions will improve tomorrow, but the NHC was playing that tune last week and the hostile conditions continued. Things in the tropics should begin to blossom soon though...its the time of year when you can wake up one morning and BOOM...just like someone turned on a lightswitch. It happened in the BOC today; perhaps the Caribbean tomorrow. Cheers!!

Need to be a little cautious with these models - a whole another suite of global models (i.e. GFS, NOGAPS, ECMWF,CMC) take the system further north and across the south half of the peninsula.

dynamic models [Re: rmbjoe1954]
      #48581 - Mon Aug 22 2005 03:24 PM

that's the first time i've seen the dynamic models.. they're a bit further south than i'd guessed, but not much. has me leaning more on the system migrating across the southern end of the state or the keys around fri/sat. probably not very intense. early next week that thing could be a very serious issue in the gulf, though.. if this stuff verifies.
joe i wouldn't relate this thing to irene (other than the slow movement concept). jerry of 1995 is probably more apt. irene was quick mid-october storm that came up out of the western caribbean.. totally different synoptic pattern. its rain shield was elongated along its track, thus all the rain/flooding in se florida.

LOW PRESSURE TROUGH ALONG THE SE COAST. WITH THIS SCENARIO EXPECT AN
INCREASE IN ELY FLOW BY WED. DO NOT ANTICIPATE SIGNIFICANT INCREASE
IN RAIN CHANCES TUE AS REMNANT OF UPPER RIDGE REMAINS ACROSS THE

AS MOISTURE INCREASES AHEAD OF SYS.

THU-SUN...GLOBAL SUITE POINTS TOWARD SLOW WWD MOVEMENT OF SYS OVER S

what is "xtrap" (black line, i assume it means extrapolation)
what is the track though? its always a straight line, i am wondering if that is simply showing the current direction of movement?

that's it. extrapolated track off the present movement vector. it will almost always be outperformed by the models (sad when it isn't). -HF

Quick post here. Well I may not be very good at forecasting strength of a system, Im pretty damn accurate looking at where a system will go. My BOC system should be a TS and move inland late tonight into tomorrow. Its gone on forecasted track,although I thought it could of been more N, but the upper low to its w pulled it more towards it.
Old TD10 or so called I should say should develop more into a TD over the next day or so. Movement will be wnw then NW. I place it near Nassau ( somewhere) by weds night. Then as the trough exits out and ridging builds over the SE, expect a crossover of S florida from the Keys-Melbourne by Friday. As it gets into the SE gulf the steering flow will be weak as the ridge slides N of the bahamas and a weak trough moves into the SE US late this weekend into early next week.
Overall movement will continue to be slow. Strength? Ill leave that to people who forcast those better.

Hey all...check out this VIS SAT. Awesome view.

Clearly visable is TD 11 BOC storm, XTD10 is definitely showing more TD characteristics.

But of interest....look at how impressive 97L looks from this angle even in its current condition.

i can't resist but i do remember you did have many comments on Emily going north.Each time it took a jog north you had it going over cuba and there was another you said was going somehwere i remember but then when it went elsewhere you dissapered from posting.

So not bashing you but like many others on here we all have been wrong on paths as well as how strong.

Here is the site's SATs in their entireties. You can check out XTD10 on the E.CARB (obviously) loop..shows nicely.

It already looks like we have Tropical Storm Jose in the BOC and it appears to be gaining strength fairly quickly. It looks a lot better than Gert ever did.

The Bahamas system looks interesting, with a southwesterly surface wind being pulled off the eastern section of Cuba. The upper low to its north should keep any development in check for the next day or two, but the upper air conditions should improve thereafter. This could be an interesting system if the planets align just right.

97 Invest is a HUGE circulation, but it is already pretty far to the north so it would have to stay pretty weak to make it across the Atlantic without turning north ahead of the trough off the US east coast.

TD 11 is still a 30kt depression, but recon isn't out there yet. Kinda curious as to why the package came out to early if recon is supposed to be there for a fix by 5p as per the report (and was close at 4p), but oh well. Do expect a special advisory to bump this up to a TS -- Jose -- within the next hour or so. And no, unlike the initial 5p discussion said, this won't be storm #11 for the season...just #10. They'll correct that, too.

Low center might be trying to form on the NE end of the disturbed area in the Bahamas, due north of Hispaniola and due east of Homestead, FL, but it's not closed yet and winds are light in that area. It's got the potential for development, but it's not going anywhere fast over the next few days, giving us plenty of time to watch it. General track towards S. Florida over the next few days is likely; beyond that, too early to tell. Edit: check water vapor...definite upper-low is what is being reflected there. Gotta work it's way down to the surface -- not out of the question -- but it's going to impede anything else from getting going in its immediate vicinity in the near-term.

If nothing else, 97L has consolidated somewhat. The convection on the southern end is gone and new convection appears to be trying to fire near the low-level center near 17N/34W. Will have to watch the trends with that overnight, but if it holds together, it'll probably become a depression sometime tomorrow or Wednesday. Area just along the coast has impressive convection but not much organization yet...still one to watch over the coming days.

More later if I get a chance, though with TD 11/Jose about ready to move inland, there's not a whole lot to update...yet.

Recon reports [Re: Clark]
      #48595 - Mon Aug 22 2005 05:27 PM

No vortex report yet, but the first few recon reports near the system suggest it is a tropical storm. They are flying at very low levels -- between about 750 and 1000ft -- and have reported winds to 48kt on the SE side of the circulation. Pressure is being reported around 1003-1005mb. Winds along the north and east sides of the storm suggest a definite closed center...only a matter of time before we get a vortex report and an upgrade to Jose.

This is typical in a low-midlevel circulation that comes down to the surface. Most mid-latitude systems that come down to the surface generally get to TS status soon as the winds in the midlevel are already from 35-60kt......I expect maybe 50mph right now, give or take 5tkt

Well Jose looks set to be a shortlived storm, likely going inland tonight and nearing dissipation by this time tomorrow. Still, yet another one for the record books!

As far as xTD10 goes, it certainly seems to be giving yet another attempt at a comeback, and has gotten a little better organised. If this trend continues we could see it reclassified later tomorrow.

97L. Well, this is a huge circulation, which actually may not be working quite in its favour. I think that it could take a little longer yet for the whole system to consolidate, which it seems to be trying to do. Probably have to wait a day or two for classification of this system too.

Certainly seems to be firing off again as we approach the peak period of the season. And there will be plenty more to come before the year is out!

Since navy has the area in the Bahamas as 10LNONAME the is would most likely be reclassified as TD 10 not anything else just to clear that up to any one who wanted to know. Just for superstitious people this would be the 3 time 10 would be trying to make a comeback so you know what they say 3rd times a charm so I would say it would come back it looks better than ever since it was in the central Atlantic.

TS Jose, 50mph, 1002mb [Re: NONAME]
      #48602 - Mon Aug 22 2005 06:38 PM

winds expected to reach 60mph before landfall; we broke the record now for earliest tenth storm of the season (by less than 24hours)--the earliest 11th was Karen and the earliest 12th was Luis, both in 1995, and both on August 28.

we may break both of those, seeing as today is only the 22nd--Katrina may form from former TD10, within 72 hours if it does, and either 97L or the system behind it could become Lee before six days time (Lenny was retired in 1999)

note: this is not wishcasting (although it would certainly be a bit interesting to see); i do honestly think that we will have at least one storm out by Africa, at least by the end of the month, and i also think it is becomming increasingly possible for XTD10 to redevelop. It has hung on for 8 days now, without being classified, and has gotten into a less hostile area.

it is also still quite likely to have a very active season (we have already had an average number for an entire year, and there has NEVER been a year with nothing developing in September). Last year, 7 storms developed after August, which would match Clark's prediction (i think his was 17)

anyone else's thoughts on 10L, 97L, and the system behind it forming into storms at any point?

Edit: I'd love to take credit for the 17 prediction, as that is looking pretty good from where we sit now, but that's all HF. I was down for 14. --Clark

Looks to me like that little red areea on the IR could be the beginnigs of a CDO... of course, i could be way of base here, but given the reasonable quick development of this system, it is certainly possible.

No dude, that is an Infrared loop. No eye... quite the contrary infact. The reds and darker colors signify intense convection, and perhaps, as Rich B said, the cyclone is attempting to form a CDO.

Look at the overshooting cloud top in the visible loop. That is what you are seeing:
http://www.ssd.noaa.gov/GOES/FLT/T1/RGB_loop.html


EDIT: Uh, yeah... that is why they have names that span over multiple demographics. The US isn't the only place hit by hurricanes, you know.


EDIT II: ah... sorry daniel. Perhaps I used the wrong terminology. Not as in a severe thunderstorm. You are right.

If the 18Z GFS is correct, I found 4 landfall points for xtd10. cuba, Keywest, Pensacola, and New orleans as it makes the final landfall in about 336 hours. Would love to see a model track of this loop

The 8 PM EDT Wrap [Re: NONAME]
      #48613 - Mon Aug 22 2005 08:03 PM

Jose', should be making landfall in the next 6 hours or so...being he's only about 40 miles from the beach as it is.

The link above, referring to XTD 10 is a Surface based, precip loop and Does Not imply anything other than rain, thunderstorms, and a surface pressure of around 1008mb.
The vorticity structure of XTD 10 remains aloft, to some degree. As evidenced in the 850 and 500mb level plots.

**I will go along with you on the connection between the Turks/ Caicos vortice and the GOM vortice. I'll have to look at the run to run continuity. Although there is a break in the signature...it remains in the general vicinity.

I believe this is what Lysis was referring to.

http://hadar.cira.colostate.edu/ramsdis/online/trop_ge_storm_relative_0.html

if you look dead in the center you can see that there is an overshooting cloud top. Makes it look very symmetric.

Interesting twist to the 18Z GFS and 12Z ECMWF models in that both now take a developing low pressure across S FL into the SE GOM and then slowly move the system north along the west coast of FL. Yikes!

Very interesting runs there Ron. Also important I think is the fact the GFS kind of stalls it out along the west coast, as from 96-144 hrs, movement is very slow.

Accoding to Accuweather tonight, the weaker the high, the worse it is for Florida. Despite the need for rain in some areas of the state, a slow crisscrosser regardless of intensity (TD/TS/H) would not be a good thing. The latest model runs (BAMMs, LBAR, etc) did shift a little more north than they had been previously. Obviously we need a true LLC before the models can spit out truly accurate info, but those runs were eye catching.

Edited to add another model showing the "end around" of Florida: Model

Once again, Skeet comes through!

I've noticed that most of the model animations that are being posted use the surface level pressures.
While these are fine in determining surface pressure and precipitation.
The Upper Air level animations should give a better idea of the vorticity, or spin, of the systems.
Try looking at the 850mb and 500mb level animations.
A tropical wave or depression would be visible in the 850mb levels.
Whereas a Cat 1 hurricane should extend into the 500mb levels and possibly into the 250mb level.
It will give you a better idea of the depth of the storm. 3-D if you will.

Local Update [Re: Big Red Machine]
      #48628 - Mon Aug 22 2005 10:15 PM

Here is tonight's take on the situation from a local WPB meteorologist who has been advertising for days a possible flooding situation approaching Florida at a snails pace:

Rich, that is a very good analogy of Jerry.....Although the upper atmospheric conditions are not what I call the best for this situation..The one thing I looked at is the steering winds up to mid levels which reveal to me that this system will be slow to move and given the fact that with the sun's unusually high solar radiation and little in the way of rain the water temps jumped up quite a bit. This may have been the contributing factors for Jerry in 1995 but in this case though this tropical wave heading our way is actually going to move just south and we are in the wettest part of it..a 1008 mb tropical low by late friday night on the GFS is no joke to me..in fact a slow movement in the area of our adjacent atlantic and more specifcally the keys and the gulf is really a concern ...a 1008mb low to me already means a tropical depression...even if it moves slowly westward across the keys Friday and slowly turns northwest actually going around the entire offshore peninsula from the southeast coast to the west coast of florida...into the weekend...this is really a system to watch out for a deluge of a rainmaker!

The NHC data is the old data from 8/14 - the last discussion they released on this storm. We are working on an issue with the UKMET models, which do not show up in our system if the UK Mets don't include the NHC identifier in their data, in this case, AL102005.

edited to add...
The UKMET models should magically appear in the right location once this issue is resolved. The thumbnail above and the iimage it links to updatd automatically as model data is added to our system.

Xtd#10 [Re: SkeetoBite]
      #48634 - Mon Aug 22 2005 10:41 PM

Sounds like even the NHC is unsure whether the disturbance is Xtd10 or not. U remember something similar happenning last year with Ivan when it reformed as to whether it was really Ivan or not.

So I'm guessing since the models and Navy are still calling this TD10, that is what the NHC will go with?

Here is the excerpt...

Quote:

CLOUDINESS AND SHOWERS EXTEND FROM EASTERN CUBA AND HISPANIOLA ACROSS THE SOUTHEASTERN BAHAMAS AND THE TURKS AND CAICOS ISLANDS... AND INTO THE ATLANTIC FOR A FEW HUNDRED MILES. THIS ACTIVITY IS POSSIBLY ASSOCIATED WITH THE REMNANTS OF TROPICAL DEPRESSION TEN. GRADUAL DEVELOPMENT OF THIS SYSTEM IS POSSIBLE DURING THE NEXT DAY OR TWO AS IT MOVES WEST-NORTHWESTWARD AT ABOUT 10 MPH.

Models [Re: SkeetoBite]

Here's an interesting take on Models-Tropical Computer Models, that is.
The models are indicating Jose' to be near 23-24N/ 111-115W in 96 hours. No problem there.
Intensity models are in strong disagreement.
SHIP model is forecasting 102kts- over land and mountains!
DSHP model is showing 27 kts-most likely!

NHC has tasked an INVEST flight into the Bahamas for 18Z on Tuesday. With Wednesday's Flight tasking into a 'Cyclone'...indicating a Tropical Depression at a minimum.

SHIPS Intensity Forecast for the system formerly known as TD 10.
8/28/05 00Z-or Saturday Evening
78kts...SST near 30C...located near 23.8N/ 87.6W.
**this is an intensity forecast. Please refer to Official NHC forecasts for Tropical System Statements, Watches and Warnings

If I remember correctly my readings on the models at NHC, none of the intensity models have been designed to take land into account. I'd guess that's the problem with Jose and the mountains.

P.S. - would a moderator mind changing BigRedMachine's super-long link into a [ URL ] tag with a short name? It makes everyone's posts scroll funny
I shortened the link and Big Red fixed what I had done!..it's fixed.~danielw

Daniel: Building on what Random wrote, I think SHIP does not take land into account, but rather assumes the cylone (in this case, Jose) will be moving over water during the entire period of the model run. DSHP attempts to take into account the actual terrain the cyclone will pass over. Of course, the output from both depends in large part on the input and on the projected forecast track, among other factors....one mountain can make a huge difference. So the difference in the "forecasts" from the 2 is not unusual.

>>It will give you a better idea of the depth of the storm. 3-D if you will.

Also presumes that a system is stacked. It's pretty usual that with the US Generated model (GFS), various layers show vortexes at different positions where they don't usually align. While the upper vort-maxes and features are helpful for guidance and tying everything together, without a mature "stacked" storm, they're all guestimates IMHO. Using the surface plots and then looking at the 200, 250, 500, 850, etc. can help narrow down range of future motion and hone in on whether that model sees true intensification and to what depth. But ultimately we live at the surface, and if a model is correct, that's the weather we'll be seeing down hea'.

Steve
Thanks, Steve. Here at work, my thought train gets interrupted. You painted a better picture. I used to check the SFC plots. Then I realised that you can have a shower at the surface without having a vortice above it. The opposite is also true. An elevated vortice may be present with out a surface reflection.~danielw

To follow on from your post, and clarify my own:

"Similar to SHIFOR, SHIPS was developed from cases where the storm track did not cross land."

the FSU model has TD 10 near cape canaveral then moving west across the state and another storm a couple hundred miles east of it ?? is this a good model at all??

It seems to do better with Trop. Storms and above...i.e. better signature. Be sure and check the model run time, as they don't always update very 12 hours.

You can get to it at http://moe.met.fsu.edu/mm5/ as it runs; the runs later get input into http://moe.met.fsu.edu/tcgengifs/ with some additional/different products there. The model does reasonably well with the overall pattern & its features, but there hasn't been a real system out there since we changed the convective scheme in the model about 10 days to two weeks ago (Irene occurred during the middle of that). Thus, we don't know entirely how well it is going to perform from here on out. My guess is that intensity will be underdone, but it's a necessary trade-off to keep terrain features from playing a huge role.

Generally, it is run every 6hr when there is a tropical storm in the basin and every 12hr when there is not one. Technical glitches sometimes interrupt the runs.

Orlando. It's showing the 12Z run right now. That would be the early (sunrise) Monday run. Latest runs tonight should have 0823/00Z, or something similar on them. Right now the GFDL on ten-L would be the latest of all those models.

Clark, they changed the parameters? I thought it was doing really well as it was.

Thanks orlando and Clark
I think you may be right orlando but I'm not that good at reading these models. Still learning I had enough last year with Frances and Jeanne right on top of me just got house repaired and I for one am on pins and needles. I am fascinated with these storms but I tend to favor the fish spinners
I can't help but think of last Labor Day and Frances beating my house for seems like two days

Looks like the GFS no longer develops #10 through 7 days...
http://www.nco.ncep.noaa.gov/pmb/nwprod/analysis/namer/gfs/00/index_m.shtml
Nam/ETA could be interresting (FWIW) moving up the coast of fla and near Melbourne as a 1004mb TD by day 4
http://www.nco.ncep.noaa.gov/pmb/nwprod/analysis/index_carib.shtml
Im not so sure but dont think NAM is a good model for tropical systems BTW

earlier i was progging xtd 10 to reform tuesday... may or may not get that one. the mid-level vorticity and surface trough/weak low are still lined up, but convection has been spotty and jumpy all day. part of this has to do with the diurnal convection associated with hispaniola and cuba. with that wave approaching from the east and the shortwave ridge trying to build over it as the upper low to the north slides west.. the thing should become better organized tomorrow. whether it's a depression is more doubtful, but i'm fairly sure this thing will be a tropical storm in a couple of days.
away to the east 97L is getting closer to warm SSTs. it's slowly becoming better organized.. should start to rev up pretty good when it gets closer to 45w. as before.. probably going out to sea.
jose is the third system to rapidly form over the BOC this season and slide westward. the area around tampico/veracruz is being pummeled by midgets this year.

Models2 [Re: HanKFranK]
      #48649 - Tue Aug 23 2005 01:02 AM

The updated/ latest models are in.
Hank, I'm in agreement with you, as usual, on the Tropical System in the Bahamas. Strange as it may seem the GFS has totally lost the signature in the 23/00Z model run.
The NAM is plotting the system but nil on the NGM, to no surprise.

I mentioned earlier that the NHC models had Jose' way out west at 102kts in 48-72 hours. I checked the latest GFS run, and it is forecasting nearly the same thing. I failed to notice that the 23N/ 115W coordinates were well into the E. Pacific. So Jose' may become the first ATL storm to cross over Mexico into the Pacific this year. 48 hours should tell us whether he will make it or not.

Danny -- yeah, a couple of parameters were changed, mainly to account for the problems that the model was having with terrain-induced areas of lower pressure hitting warm SSTs and rapidly spinning up into hurricanes.

I don't think Jose stands a chance of making it to the EPac as a trackable tropical cyclone. Some mid-level energy from the storm may make it across to the East Pacific and bring about a near-shore tropical storm there, as some of the models are calling for, but given the very small size of Jose and the amount (and type) of terrain it will have to travel over, I don't think we'll see it make it there as Jose, if at all.

I'm going to throw up a quick update on the blogs in just a bit with more.

the system that Stephen King would be proud of.... [Re: Clark]
      #48652 - Tue Aug 23 2005 04:18 AM

I am going to be very curious what visible light brings for former 10. the system that refuses to die. Can't really tell from IR what's lurking down at the surface. I don't think it's organized yet, but it's not for lack of effort at this point. Heck, I imagine everyone and their golden retrievers are watching this system. I still find it interesting/amazing how stubborn the system has been. (even if in general it's probably not the origional TD10 anymore... it's close enough)

Anyone else want to say TD at 5PM today? Caveat being, that there is a LLC somewhere down there and the system continues to organize and the storms don't die as soon as I go to bed

Mark,
i will kind of join you in saying it 'COULD' be a TD today. IR imagery shows some improvement in the organisational structure overnight. First light visibles should be interesting, and with the Recon going out later we will no doubt find out for sure if it has succeeded in making a comeback.

97L has also become better organised overnight, and i think we could see it classified today. Dry air to its west is giving it a somewhat lopsided appearance, but the upper-level conditions arent bad, and the SST's are warm.

From the Extended Outlook for West Central and Southwest Florida:

THE COMMON THREAD TO THE SOLNS IS THE DEEP TROPICAL MOISTURE MOVING OVER THE PENINSULA FOR THE PERIOD...SO SEE NO REASON TO GO LOWER THAN 50 POPS EACH DAY. WILL BUMP POPS UP TO 60 PERCENT CENTRAL AND SOUTH FOR FRI AFTN ONLY...AND GO WITH SCT POPS OVER THE COASTAL WATERS FRI NIGHT. WILL HOLD OFF GOING TO 60 PCT FOR THE REST OF THE PERIOD UNTIL WE ACTUALLY SEE FURTHER DEVELOPMENT WITH THE TROPICAL SYSTEM.


Interestingly, the forecaster who wrote this mentions twice that the NAM model brings a tropical storm to the Florida east coast, but discounts it, as he is sticking with GFS for now.

The model runs this morning seem unanimous in bringing something across southern Florida. Which makes me wonder what the FSU superensemble shows, since historically it performs the best. Can Clark or anyone confirm that the superensemble is in agreement with the other models? Or does the superensemble only get run for genuine storms, and not mere waves? Sorry for the stupid question, but I'm still trying to learn.

X10 97L [Re: Rich B]
      #48658 - Tue Aug 23 2005 06:22 AM

Rich, 97L is looking slightly ominous this morning. The size of the system as a whole is very unusual. Even on Infrared loops it appear to cover over 1000 nm.

X10 looks to have kept most of the Turks and Caicos residents awake for the last few hours with consistant lightning and thunder. Area of dry air to the NW of the vortice center. Hasn't managed to choke off the system ...yet.

Looks like Rabbit might have to get out his magic bag to kill this one!

Becky. No question is stupid. My Drill Sergent used to say that the only question that 'was' stupid. "Was the one you didn't ask".

That aside. Most of the NWS folks use the GFS consistantly...so when it throws a curve, like it did last night. They discount most of the other models and stick with the GFS. The NAM is progging a Tropical System in the Southern FL Peninsula area. So 1 out of 3 of the main models picks up the system.
There will probably be more than 1 Forecast Discussion throwing the NAM solution out the window today.

http://moe.met.fsu.edu/tcgengifs/
All of the models updated at 00Z last night.
Be sure and check out the CMC model!
