To eliminate any and all confusion to some of the readers here.
This is the Final Advisory on what was TD 10. Issued 12 hours ago.
There is No TD 10. Only the remnants remain.
End of discussion. Until makes a determination that it has regenerated.
Any further posts will be removed from the board.
TROPICAL DEPRESSION TEN DISCUSSION NUMBER 4
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 AM EDT SUN AUG 14 2005
VERTICAL SHEAR ASSOCIATED WITH AN UPPER-LEVEL TROUGH JUST EAST OF THE LESSER ANTILLES HAS TAKEN ITS TOLL ON THE DEPRESSION. THERE IS STILL A LOW-LEVEL CIRCULATION AS EVIDENCED BY LOW CLOUD MOTIONS AND A QUIKSCAT PASS...BUT IT IS WEAK...20-25 KT. BECAUSE THE SYSTEM DOES NOT HAVE SUFFICIENT ORGANIZED DEEP CONVECTION...IT NO LONGER
MEETS THE CRITERIA FOR A TROPICAL CYCLONE. THEREFORE ADVISORIES ARE BEING DISCONTINUED AT THIS TIME. SINCE THE VERTICAL SHEAR MAY RELAX OVER THE NEXT FEW DAYS...THERE IS STILL THE POTENTIAL FOR
REGENERATION...AND THE DEPRESSION'S REMNANTS WILL BE CLOSELY MONITORED.
THE SYSTEM HAS TURNED TO THE RIGHT AND INITIAL MOTION IS ROUGHLY 320/6. THE REMNANTS ARE LIKELY TO MOVE ON A GENERAL NORTHWESTWARD TRACK...TOWARD A WEAKNESS IN THE SUBTROPICAL RIDGE...OVER THE NEXT FEW DAYS.
THIS IS THE LAST ADVISORY ON TROPICAL DEPRESSION TEN...UNLESS REGENERATION OCCURS.
FORECASTER PASCH

It's near the diurnal convective maximum, so the standard short-term caveats apply in this case, but TD 10 is looking, well, like a tropical depression once again. Convection has flared up around the center in curved bands, primarily to the northwest and notheast of the center. It is still in a shearing environment and will likely remain so for the next day or two, but it is looking quite a bit like Irene did for several days. I mentioned earlier that I'm not sure why the downgraded it so quickly, particularly given what they maintained with Irene, but they are the experts and I'm not going to say it was a bad call...just one I'd like some clarification on.
If current trends continue, I expect they'll pick back up with advisories sometime Monday. That said, I'd only put it at 50/50 that current trends continue, given the shear in the vicinity of the disturbance. No matter whether it gets picked back up or not, it should continue largely to the west or west-northwest and be near the northern islands in a few days. The weakness of the storm plus it missing the weakness from the trough to the NE are the culprits in this motion. Beyond that, model solutions diverge, with the potential for this to either head back out to sea (NOGAPS, ) or turn more towards the west (GFS, UKMET) -- needless to say, it's way too early to make a forecast on this, given that it isn't even a depression right now.
The forecasts a more favorable upper-level environment to develop near the storm in the next day or so, while the UKMET tracks an identifiable entity through 6 days to a position near the Bahamas, suggesting some development may be possible later in the period. The is a bit more bullish than the on developing this ridging, a departure from what was forecast in most of yesterday's runs. They will all have to be watched for continuity and to see if this all actually occurs, but given the model concurrence, it's a good bet things will get more favorable through time.
So, to recap...it's not TD 10 right now, but it's not out of our hair just yet. We'll watch it.
Interesting to note...it's 5-6 days out, but all of the models are picking up on a strong feature coming off of the coast of Africa at that point. Another upper-low is forecast to build into the central Atlantic in 3-4 days, but start to move out about the time this feature hits the coast. The favorable environment conditions are coming, as advertised...we'll have to see how this pans out.
More Monday or Tuesday.

The latest wave coming off Africa has finally not disappated. Looks like the Sal is decreasing off Africa and the trough that was out there is moving away. There seems to be a low around 18w 11n as the wave comes off. Will this be the locomotive?

Can we finally put Irene to rest as far as the is concerned? Hope so as it's definately just a threat to fishermen on the great banks brining in their catch.
TD 10? looks to be just a simple flareup of thunderstorms heading generally in a NNW direction. Definately nothing to be concerned about.
All seems well in the tropics at least for now.

Kind of a slow morning. Anyone with any thoughts on the SW Carribean? What about the wave dropping SW towards PR...is than anything?

so, as of now, besides Hurricane Irene we have nothing to worry about for a couple days at least, i just hope that maybe this will be a quiet period of sctivity in the troics, all we can do is wait and see. Could someone refresh my memory, whats peak of the season?

Actually there is still a LLC, just to the south west, associated with this convection . Follow this link. Click on animation then 30 image loop then double click on the remnants of TD10 and you will get a 1Km loop of this area. Do not click on animate image below. You can clearly pick up the LLC moving west right along that latitude line. Hopefully you have a broadband connection.

Irene appears that it is still strengthening, and the eye is now very evident on visible images, although seems to be covered with thin high clouds, which is why it is not showing up on the IR image. TD10 seems to be completely done with, i expect what little is left of the LLC to completely disappear by midweek.
Irene going out to sea, TD10 dissipated, and nothing looks like it will form--we seem to be in that brief lull that is seen at some point in every August. Some examples just in the last decade:
2004: nothing formed Aug 15-24 (the week before developed)
2003: August 16-27 nothing but a TD on 8-21
2002: NOTHING between Aug 9 and 29
2001: the quiet period between track segments of Dean (Aug 23-27)
2000: NOTHING in August after the 24th
1999: entire first 17 days
1998: entire first 18 days
1997: entire month
1996: entire first 18 days
1995: nothing formed Aug 11-21

I've been seeing in other places that they are talking about the dust coming off of Africa as an inhibiting factor as it's drying the air. It makes sense, but it has to end sometime.

The wave coming of a Africa look healtheir then any that i have seen this year it looks like it could be associated with a low. Met do you got anything on this one and are any models devloping it. Here is a attachment of it

As a practical matter I think that the did not want to have TD-10 in it's current state effect their forecast error. Aswe all know the strength of the storm has a major effect on the track. As they found with Irene, they could not predict the strenght and missed the forecast path. Since this is no danger and not knowing if or when it will develope, no need to forecast a path what will be wrong. The "1st." models had the storm moving hundred of miles in a different direction than the current local.

Rabbit, nice summary of August calm periods. Really not unusual. You may be right about former TD10, but it still has a pretty impressive LLC. I remember Irene in a similar situation not too long ago. If it can survive the shearing environment another day or two, it may have a chance to develop convection around the center again. And it's alot further south in latitude, which over the long run probably gives it more favorable conditions to develop.

Look Like What is left of TD 10 is just a remant low it looks like it is dissipating and I dont think the LLC will last till the shear relaxes I think is spose to realaxe in 2-3 days but i'm not sure some could help me find this out I would be very happy. It had almost none if any convection left. So anything intressing going on in the basin sence Irene Is Heading out to sea and 10 looks dead what is next.

Means right now Old TD10 is moving west no signs of coming back right now, However if in a few days it does become a TD again we just may have a GOM problem instead of a East Coast problem.
