Initial Recco observations seem to support at least a tropical depression, however I'm going to wait a bit to make sure. A circulation hasn't been found yet.

If you are referring to the recon flight information, I get it from a subscription program called Hurtrack. It takes all the information from and provides it in graphic format. Also provides recon flight data as received and publishes it on a map so you can see where they are...

You can find Recon Messeges at the website and go to the left in the blue You will find Aircraft Recon in the Storm info area.

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 & 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.

Here's a nice high resolution VIS SAT of the bahamas system.

I happened to stumble across this collection of models from Penn State. They call it the electronic wall. Looks to have almost every model on there so you won't have to jump around from different websites looking for something. They even have satellites, visible and IR.

Sorry if this is in the wrong area mods!

Sounds like if former TD 10 gets into the Gulf it would eventually landfall on the east gulf coast, and not head more west towards Louisiana or Texas, correct? When will they have a better handle on where the storm will track if it does become a depression/storm?

99L keeps disappearing from the list anytime you click something on the site--i have a feeling they are in the process of changing it and we may have TD12

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 -- 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...

I put up a new main page article on this because it'll be getting a lot of attention soon. I don't expect much out of it, but it will be interesting to track.

HPC confirms Clark's thinking on the system.
From this afternoons NWS HPC Extended Weather discussion:

TO THE SOUTH OF THESE HIGHER LAT ANOMALIES...MID LEVEL HTS ARE

NATION. THE STRENGTH OF THIS RIDGE AND THE DEGREE OF WEAKENESS IN
IT WL BE CRUCIAL FOR THE TRACK OF THE AREA OF TROPICAL WEATHER
INVOF THE BAHAMAS THAT MAY AFFECT FL AND THE NERN AND NCNTRL GULF
THIS PERIOD. THE MAJORITY OF THE MED RANGE GUIDANCE INDICATE THIS

ALONG THE SERN COAST MON-TUE. THE ONE THING ALL THE MODELS DO
AGREE ON IS THAT THERE WL BE EVENTUAL WEAKENESS IN THIS UPR RIDGE
FROM THE STREAM OF STRONG SYSTEMS PUSHING IN THE NRN STREAM ALONG
THE U.S./CAN BORDER. THIS WOULD THEN SUPPORT A MORE NWD COMPONENT

THREAT FOR THE CNTRL TO ERN GULF COASTAL AREA BY THE BEGINNNING OF
NEXT WEEK. SEE LATEST TPC DISCUSSIONS FOR LATEST UPDATES ON THIS

so am i right to assume that if an invest disappears off of that it is about to be changed to a TD then ? (unless of course it is dissipating which this one isnt)

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.

this is likely developing in a similar manner to earlier in the year in that when it first formed there was a closed circulation, but no difinitive swirl or center, but instead a broad disorganized rotation
