Jose's Landfall and Former Tropical Depression 10

11:45AM Update
ExTD 10 will likely be reclassified as a new system if it develops. The navy is now referring to it as 99L instead of Former TD#10 which would imply renaming. Recon aircraft are heading out there this afternoon to check to see what the area is.

Folks along South Florida will want to pay extra attention to this over the next few days.

Original Update
Tropical Storm Jose made landfall over Mexico a little north of Veracruz. This short lived storm will be another large rainmaker for Mexico.

Proximity to the US and other factors, as well as another persistent flare up have forced attention back to what was Tropical Depression 10.

Recon aircraft will likely head out this afternoon if it continues to persist today. The models are not a good indicator of what the system might do at this time, however there is a decent chance once again for this to reform.



Some call it to remain south of Florida, one ventures it more north, and yet another calls for slow erattic movement up the east coast of Florida a bit and back down. In other words, there is too much divergence to take any stock in those at the moment.

If so, it will be close enough to Florida to watch for strengthening. The area it is venturing toward may be allow it to develop. There is dry air near it, which brings enough of a check from having it strengthen too much, if it does at all. At least until it gets into the Gulf.

The chance for redevelopment of TD#10 by tomorrow night:
Code:

forget it) 0 1 2 3 4 5 6 7 8 9 10 (sure thing)
[------------*---------]



Beyond that, the waves off Africa haven't looked as impressive as they were a few days ago, but the core convection has persisted, so we may eventually have to watch that as well, although out to sea is the most likely ultimate track for that.

It has broken away and spans a fairly large area still. It does have the potential to develop several days down the road, but will most likely remain out to sea.

Re: Jose's Landfall and Former Tropical Depression 10

I imagine the main reason the models are so inconsistent is because they aren't sure where the real center of the "wave" is and in this case location is everything. Question remains...where is the surface low? Where you start the models makes a big difference on where they end up. Can't wait to see what if anything recon finds. Nice blow up, begs attention.

Re: Jose's Landfall and Former Tropical Depression 10

Big flareup of convection this am with SE Bahamas Trop Wave. Hard to tell but it looks like a circulation just to the west of the big blob of TS off the NE coast of Cuba. A couple of this mornings model runs are really scary. The 00Z CMC, whic has been forecasting a rapid deepening in the GOM once the system crosses S FL, creates a major hurricane in the eastern GOM and then tracks it north along the west coast of FL into the panhandle. Now the 00Z UKMET has jumped on board with a bombout in the eastern GOM too. The track seems to be getting better in focus with a closed circulation forming in the western bahamas drifting to the SE FL coast, across the southern tip of the peninsula and into the SE GOM. The 00Z NOGAPs supports this track. Yesterdays 18Z GFS did also but the 00Z GFS loses the system. All in all, gonna get real interesting the rest of this week.

Re: Jose's Landfall and Former Tropical Depression 10

[moved from old thread]

Ok, NHC is very late in getting their 5am TWO up...given that it is almost 7am now...wonder what is going on? TWD from about 4.5 hours ago says there is a new wave off Africa. Yet another one to watch! Plus a wave over central America and another out in the Carribean...in addition to X-TD10 and 97L.


97L - Looking at IR:
97L Looks VERY good. It looks like it has consolidated down to a central spin, and appears to have a comma-shape with good circulation and banding to it. It has also shrunk in size, no longer the huge blob that it was, it is now a much smaller more defined system.

There hasn't been a Dvorak reading on it in about 5 hours, but what the satellite animation shows is it getting its act together in just the past 6 hours. I'd expect a decent classification soon. This might be why NHC hasn't gotten their TWO up - perhaps they are waiting on information about 97L?

Models are still inconistant on the strength and track of 97L, but they should become better once we see a TD out there. Whether it turns to sea or keeps westward is still unknown, but the models seem to think a turn to sea is likely.

I'm going to take a wild guess and say we might have a cyclone out there today just based on the IR sat.

----------

X-TD10:
Again, the IR presentation is very good this morning, though I'm not seeing rotation to the signature. Again the models are highly divergent on what exactly it will do, with some strengthening it and some ignoring it. Again, once (if) it makes a TD it should get better model guidance. This is still a wait-and-see system, though I expect we'll have a cyclone within a few days.

---------

Any met: why have the GFDL models for 97L on both PSU and FSU been all missing images? NOAA has to be running the models or they wouldn't be listed, but why isn't there any data on those websites?

Well, NHC just posted their TWO timestamped 5:30am. Someone forgot to upload it?

They aren't mentioning much about 97L other than it has organized better since their last update. Seems conservative given the Satellite signature I'm seeing.

We could use some rain here in SW Florida, but not to the extent that the CMC and UKMET are showing, that's for sure!

To Daniel, yes I saw the CMC this morning. Three storms all in a row! However, since that model has not impressed me much this year, I'm not putting too much stock in that solution.

Re: Jose's Landfall and Former Tropical Depression 10

Yeah, I just checked CMC. I usually ignore it since it doesn't do too well with tropical systems (overstrenthening them), but I have to say, it looks impressive.

It takes X-TD10 to a strong system into the gulf and 97L to a strong system sitting out at sea. Meanwhile it builds a THIRD system off the Bahamas and sends it north. It is the only model does does anything off the Bahamas.

I wonder if it is accurate on this or not? I'd say no, but this has already been a wild hurricane season so anything's possible.

Re: Jose's Landfall and Former Tropical Depression 10

New GFS model run out:

I'm not liking what it does with X-TD10. It follows the LBar track on Skeetobite's graphic, heading into the east coast of FL, hovering over FL, then bouncing off and heading back into the Atlantic and up the eastern seaboard toward NC. EEP!

It also spins 97L out to sea, but it develops the wave behind 97L into something that heads toward the Carribean at a very rapid spead, reaching the Lesser Antillies in 6-7 days! That seems almost too fast for any sort of development, but it bears watching nonetheless.

----------

Also, quite an impressive sat photo of 97L over at NRL!

----------

Also, NRL is tracking 9 systems, either formed or invests, between the Pacific and the Atlantic. Wow.

---------

Also, take a look at the latest satelite Wind readings from 97L.

makes me feel a lot better tho. The third system out on the GFS run.... not only
is if fast, but very far south, then further south, then moving more north. I hope any
CV system doesnt run that far south that long, it makes it easier for it to reach the U.S.

Re: Jose's Landfall and Former Tropical Depression 10

Noticed on the CMC & Nogaps at around the 96hr time that the high over the Mid Atlantic area begins to move out toward the NE. If this happened this might would allow for #10 or what ever it will be at that time, to begin to get caught up in a more of a sw flow that could set up over the Fl east coast and push it more to the n-ne like that of Irene only a lot closer to the coast.This may explain the reasoning behind the new GFS run. I believe this will also depend on it strength and the speed of the system. A faster pace would allow it to get to the GOM, whereas a slower more erratic pace might would allow it to get caught up in some kind of flow from the sw. Just my thoughts this morning based on the new GFS run and overall patterns from earlier this season. J.C.

I agree, Rich, looking at the IR SAT (not always good to detect circulations), I see a CC spin about 21N-74.5W in the general location u described. Looks to be moving slowly W-NW.

Re: Jose's Landfall and Former Tropical Depression 10

Difficult to locate a possible LLCC with this one, especially as it may not even be there. I would guess looking at the visible imagery, that if there is a centre it is probably somewhere around 21.1'N 74.9'W. However, the low level cloudlines dont give much support to there being a LLCC in this region, so it may be just at the mid-levels at the moment.

Also noticed that our friend 97L has a LLCC in the vicinty of 17.5'N 36.8'W. However, the convection is removed to the east of this centre. Certainly something else worth watching though

visibles

that wind report kinda checks out with what i can see down there. there's an elongated closed low just north and west (around 22/75) the deep convection. i didn't expect it, but it looks like that upper low has strengthened to the northeast and is infusing dry air in from the north... around 15kt of shear again, too. synoptic pattern still favors this thing developing, but it's going to do it slowly. center might redevelop to the east or south as just to the east there's a diffluent outflow/shortwave ridge region.
soi has dropped negative again the last couple of days... as long as it keeps doing that the upper lows in the basin are going to keep harrassing nearby features.
away east, 97L had its t-rating jump from too weak to 1.5. that's just a function of the convective ball that started clining to the east side overnight.. the system probably isn't generating much different winds than before. it's the equivalent of a 25-30kt depression right now... the nhc doesn't like to classify these until they have a persistent convective core; this one is marginal (depend's who's making the calls, really). they'll probably do it at 11. no reason not to; it's very likely to be a tropical storm tomorrow.

Basicly They probably had some discussions and decided that there wasn't enough of xTD10 remaining in the new system to keep the designation. So if it goes to TD status, it will be TD11 (or 12).

I can understand the call, Tangentially, does anyone have any information that details the continuation of the name "Ivan"? It's a interesting compare to TD 10.

Looks like its going to be constantly struggling IMHO. Comments/corrections welcome. http://www.ssd.noaa.gov/PS/TROP/DATA/RT/watl-wv-loop.html

Just a head up that the referring of exTD10 as 99L is causing a lot of headaches with the automated plotting here, so You may want to use the old TD#10 for model animations (Under coordinates on the left) until this is fixed.

If these are surface winds and the snap shot was taken at around 10:00 Zulu, then am I seeing most of a circulation visible? About the only thing I can't find is a southerly wind. hmmm...

You can also see some 30Kt winds in and near the center, along with some uncontaminated 40Kt winds in the rain band to the east.

Now is the rain band to the east considered a part of 99L? (it is 99L now, right? *laughs* my apologies, on even less sleep than normal).

A little ahead of the game, but AL992005 (99L) will indeed become TD12 if it achieves Tropical Depression status. It may even grow up and get a name...

Much debate will likely occur over this, like last year when the remnants of Ivan reorganized. John Q. shouldn't care about the naming conventions, it just becomes an issue for the hardcore to debate.

Re: Circulation

Really don't care what they call it, its the NHC's call. What I am Concerned with is that most of the models don't develop this for another 48 hours, and I believe we will have Katrina by then. I am basing this on the visible satellite pix, relaxation of the shear, and current organizational trands. LCC seems to be coming together now and we should have a depression by 11 pm. This raises a few questions regarding its path and strength. I believe it will strengthen a bit faster than the models have been depicting, and that in itself may only play a small role in its track, however its general movement has been to the WNW/NW, and the right outliers (NAM and GFDL) may have a better idea (hate to agree with the LBAR) than the previous guidance, if only by shear luck! But I see this thing making a Northwesterly track for a day, then bending back to the WNW or west Thursday and Friday, ultimately ending up in the GOM. Its strength and WHERE it crosses is of interest for those in south and maybe even south central Florida in the near term. I'm glad recon is going out now to get a good read on this one. I don't believe the models have a good handle on it yet. They really couldn't, since no center is there to initialize on. Watching this one like a hawk. Cheers!! PS: This is not a official forecast; NHC does that.

Re: Circulation

It'll be interesting to see what the plane finds. The ULL to the north of the possible surface low has developed some weak convection around its center and appears to be trying to wrap some of the convection to the south around its east side. That may end up becoming the dominant feature with respect to any tropical (or subtropical) development. It may take awhile for this whole thing to consolidate into an organized tropical system, if it does at all.

The one north looks to be entrenched with some dry air while the one south has more of a moist enviroment. The north circulation seems to be heading NW while the south circulation seems to be heading slowly WNW.

Models have now updated: http://www.sfwmd.gov/org/omd/ops/weather/plots/storm_99.gif

Appears landfall west of the Miss. is unlikely. I'll be curious to see the runs later on when they have info from recon. Would not suprise me in the least to see this upgraded today.

Also for those wondering, the floater is off of Jose and onto the area in the Bahamas now.

I feel that another noteworthy development is the fact that the 12z GFS develops the system curently exiting Africa and takes it in the general direction of the islands in about 8 days. 06 runshowed a storm in just about the same location in 16 days (which would be a 3rd system). Obviously the long range models are only a step above the trusty magic 8 ball, but this does seem to show an unsettling pattern developing.

Re: JB

You guys need to not rely on the dynamical models. They change from run to run more so then the global models. I look at them for entertainment only. Best model to use (I feel) is the Nogaps. Others though will perform well with 1 or another storm during a season. If you look at what the Nogaps and somewhat combine the GFS,UKMET and Canadian and put a plot between them,, you will have a decent forecast. The FSU model ( not mm5 ) is decent as well. Anyways you need to look at the whole picture and enviroment data also to combine what a model might not see changing before its next run.
Right now with what could be TD12 it looks like this mornings burst might of given it life. Its burst was enhanced by a midlow over N Cuba and another to its NE. A weak low near 1010mb formed near 22.4N and 74.8W. Its movement is to the WNW with a bend to the NNW later tomorrow. It should become a TS in the next day or 2.
Im not changing my projected path ( although for florida it could go eigther way) but its going to be hard. I still expect it to be near Nassau later tomorrow and just N of Grand Bahama or 50-100 miles east of Verobeach, Fl by Friday morning. It should miss the trough and move back west or even wsw and cross the state late Friday into Saturday between WPB and the Cape. Could be a weak hurricane by then. It should move into the gulf later on Saturday between Venice and Clearwater. Movement will be slow. After that the guess would be a turn to the N and head up towards the Panhandle but that is more then 5days out. Further strengthning should be expected.
This path will be simular to Erin almost a decade ago but not exactly (of course).

Re: Circulation

So far, the recon appears to traversing the circulation in a counterclockwise manner, flying from the west side of the storm around to the south side now. I'd place the center around 22N/74W -- still somewhat disorganized, maybe not entirely closed off but getting there -- generally drifting WNW. A microwave imager pass from earlier today suggested low-level banding features beginning to develop; the infrared & visible satellite images are beginning to catch up to that. Still broad and overall relatively weak, but it's got warm waters and low shear ahead of it. Scottsvb's post a little while ago pretty much sums up my track thinking for this one -- maybe a bit further south than Erin 1995 and in line with the UKMET & GFDL runs earlier today -- with intensity still up in the air. Interests in both Florida and the northern Gulf east of New Orleans need to watch this one.

The first two reports I have from near the storm suggest flight level winds on the west side of the storm of about 25kt and sea level pressures near 1010mb. It'll depend upon what they find on the east side of the system -- and whether there is definitively a closed low or not -- as to whether or not we have a TD at 5pm.

Different area of low pressure...

Recon is reporting that the area of low pressure with the depression is not where satellite estimates had it pegged and is instead further north, at 23.5N or so. This places the center underneath a new band of curved convection forming SE of San Salvador and east of Rum Cay.

I expect this storm to be upgraded to a tropical depression at 5pm based upon the findings of a definitive closed center of low pressure. As recon has traversed the storm in a counterclockwise pattern, winds have come from the west-southwest on the southern side of the storm to the east on the north side of the circulation. Winds on the eastern side of the storm have been measured as high as 37kt at flight level (which here is about 240m ~ 750-800ft above the surface), with a pressure of about 1010mb. Given these reports, I estimate this will be a 30kt depression -- or, if it continues to organize -- Tropical Storm Katrina -- at 5pm. Still waiting on the first vortex report from the recon, but that isn't due until closer to 3pm as I recall.

Oh yeah -- 97L -- indications are that the low-level center may be reforming near a mid-level center embedded underneath the deep convection near 17.5N/35.5W. Despite lacking convection for quite some time, this storm has maintained excellent low-level banding features and now appears to be taking that next step towards development. It probably won't beat the Bahamas disturbance as I thought last night, but I do expect this to become a tropical storm before it gets to 45W...perhaps even 40W if the center is indeed reforming underneath the deep convection. Probably won't be upgraded at 5pm, but might at 11p if trends continue.

Got a feeling this place is going to get active again in quite a hurry...

Re: Different area of low pressure...

good obs clark,, hard to go against recon but I dont see it. LOL. I think they found a vortex in the main flow. I think the center is down more near 22.8N and near 75W.
Reasons comparing are there is nothing on the recon to show a closed low up there ( maybe just a vortex swirl) while the one near 22.8 clearly shows a rotation with a wsw,sse and ene wind. I guess Ill see if recon outdoes me. Just to note people,,recon is the best source of info, so this is just my speculation,,its probably that there are many vortexs in a broad circulation on a developing system. Anyways thanks Clark for the update on the recon.
