TD 2 nearly dead; African disturbance 90L gathering strength
Tropical Depression Two is near death, but is still worth watching. The dry, Saharan air to the north and west of the depression, combined with moderately high levels of wind shear of 15 - 20 knots, have almost completely destroyed all of TD 2's heavy thunderstorms. Satellite loops of the storm show a well-formed circulation, but almost no heavy thunderstorm activity.
Wind shear over TD 2 is expected to remain in the modereate range, 10 - 20 knots, over the next five days. Sea Surface Temperatures (SSTs) are 27°C, but will warm to 28°C three days from now. There is plenty of dry, stable air from the Saharan Air Layer (SAL) to to TD 2's north and west that will continue to cause the storm problems. The relatively cool SSTs and dry air mean that TD 2 will not be able to intensify quickly, and some of the models indicate the TD 2 may get destroyed in the next day or two. However, several models still predict TD 2 will become a tropical storm. The HWRF model predicts TD 2 will become a hurricane five days from now, but this seems unlikely given the dry air and relatively high wind shear affecting the storm.

African tropical wave 90L
A strong tropical wave with a large circulation and plenty of heavy thunderstorm activity is a few hundred miles south of the Cape Verdes Islands, off the coast of Africa. NHC dubbed this disturbance 90L this morning. This morning's QuikSCAT pass shows that 90L has a very large circulation, and top winds of about 30 mph. Satellite imagery from the European METEOSAT satellite show that the heavy thunderstorms associated with 90L are in two major bands, to the north and to the south of the center. There is no heavy thunderstorm activity near the center yet, and this would have to happen before 90L can be named Tropical Depression Three. Water vapor imagery shows that since 90L is forming several hundred miles south of the dry air of the Saharan Air Layer (SAL), the storm should not be affected by dry air and dust as much as Tropical Depression Two has been. Wind shear is about 20 knots over 90L, and is forecast to remain in the moderate range, 10 - 20 knots, over the next five days. Sea Surface Temperatures are about 28°C, and will remain in the 27 - 28°C range the next five days, which are high enough above the 26°C threshold for tropical cyclone formation to allow some slow development to occur. The GFS and ECMWF models continue to predict the development of this wave, though they are now less aggressive about intensifying it than they were in earlier runs. The consensus among the reliable HWRF, GFDL, GFS, and ECMWF models is to bring 90L to point near or just north of the northernmost Lesser Antilles Islands 6 - 8 days from now. The storm could be at hurricane strength by then, as forecast by the SHIPS intensity model.
I'll have an update Friday morning.

Yes ,very close to our shores,here in Puerto Rico, according to GFS.
yep =\ not good
Drak the GFS has not really wavered to much on that track for the last several runs.
thats not good
Well that kinda takes away my tranquility =\
Thar, there goes my peace of mind. It's too early still, but I guess that gives me plenty of time to get my stomach ready for a couple of weeks of canned food and warm beverages. Ugh.
GFS has been forrescasting a Cat 3 cane over PR in August 20 over the past 4-5 days if this came true will be an amaizing performanse of this model. Thriler days ahead here at PR, Sadly.
The GFS 12z wanted to send this thing riding up the eastern seaboard. No long range consistency. It's just for fun to look at the GFS that far out
same here only 30 frames lol but in the bahaamas so far
However it is interesting that there is no longer a forecasted trough along the east coast...
Just can't count on them in mid to late August.
I saw it better and I think it makes landfall between Ponce and Salinas on that run =\
link?
me too
jejeje
But, it seems the storm would first hit Florida before the GOM.
yeah that one of the things I hate more xD
I may end up trying to turn the TV on if powers doesn't come back fast
Like with Jeanne's whoops and we were without power for awhile
Well, remember Hugo. Wasn't it supposed to graze the South? We all know how that ended up. Not good either way.
Other GFS/HWRF/GFDL/WRF maps
eeeeeeek
Heck, yesterday many were left without power and it was just some rain and thunderstorms. Another Cat 3 like Georges... nah, I don't even want to think about that. O_o
yeah I lost power yesterday but it was only for one or two minutes
another Georges = No Puerto Rico
with the economy like it is that would wipe us off the Caribbean =S
That was mentioned yesterday by chucktown...it seems 9's are not good for SC!!
Yeah, I REALLY hope nothing gets or forms there (virtually impossible though). It certainly looks spooky.
I have been here all week =P
I just don't post as much as I used to... University xD
so has soon has 90L starts cooking the Admins start baning
all so this blog will be come flooded in a few days when 90L starts cooking
so if you dont want to get ban stay on key
I'm thinking it's just an old wives tale! At least, I'm telling myself that...
Well, I keep saying a hurricane it's the only thing left to happen here this year. In between the economy, the AH1N1 and the recent tremors being felt near the Island, I'm pretty sure PR is gonna end up "disappearing" one way or another. Pick your favorite destination, sadly we might have to get outta here soon.
