Re: ATL : TROPICAL DEPRESSION TWO
Nope, it looks like we may get Ana by tommrrow if it gets its act together, i think this may be a blocker for all the SAL out there for what mite be TD 3.

Re: ATL : TROPICAL DEPRESSION TWO
ITCZ is evidently helping TD2 out here, needs to stay in good proximity IMO if its to build more, interesting few days coming up

Truly the dry air to the North combined with increasing shear over the next couple days in that region will go to work on it. If it stays locked on the ITCZ it looks to pull enough moisture to get under. Either way, I think the circulation is looking stronger. We'll see a lot of pulses with Dmin Dmax though.

TD2 seems to have lost it's outflow and has become very diffuse in appearance - even I'll agree that 36 or 48 hours ago it looked very impressive - not so ATTM:

No, the Caribbean-Florida hit on the GFS is from the wave behind TD2 that is now just emerging off the African coast.

Re: ATL: TROPICAL DEPRESSION TWO (Models)
I believe there is some serious confusion as to what TD or waves are being tracked on the models. I don't think the one the GFS has by Florida is TD #2.

The convection over land (Africa) seems to be a line of diurnal thunderstorms at this point (they have that bow-echo appearance) - it's possible they will dissipate before the next 6-hour Meteosat photo become available, and the wave that just came off the land mass is now part of the ITCZ, so we'll see if it becomes isolated at some point or continues to be a part of the convergence zone weather...

Re: ATL : TROPICAL DEPRESSION TWO
highres visible seems to indicate the LLC was to the SE of the MLC until about 1845 when it looked to pop NW. Looks to be be finally vertically stacked IMO. If that was a main hinderence(there are others), then this should pop over the next 12 hours.

Re: ATL : TROPICAL DEPRESSION TWO
As long as you agree to have all of the storms that do develop head your way I'm fine with the season "ramping" up if in fact that's what it's doing now. Otherwise speaking for myself I would jump for joy if nothing developed at all for the remainder of the season.
