ATL : TROPICAL DEPRESSION ERIKA (06L)
Moderator: S2k Moderators
Re: ATL : INVEST 94L
Let's all wait for recon to know for sure - the weaker it stays the more west it'll move - perhaps even south of the islands in the caribbean. The latest tropical models (GFDL and HWRF) develop 94L into a hurricane and the ECM global develops it too. Looks like a recurve according to ECM, however, there is building high pressure moving down from New England which may complicate the track late in the forecast period.

Try more like 16.7 57.0. That best agrees with an extrapolated track of best tracks 1145 position of 16.4 56.6.

I have no idea if it's an llc forming, or just another swirl, but I see it.
I see east winds throughout that area ...

Re: ATL : INVEST 94L
I don't think that's an LLC forming up by 18N. My eye is drawn toward about 16.7N/57W on the high-res loops. Generally, if you have to hunt for an LLC with no convection obscuring it, then it isn't there.

Direction looks like only 275 degrees. Practically west.
If it bursts again tonight it still has something.
Might crash on the islands.

That's probobly more of a MLC that is trying to get down into the surface, but its elongated and not complete. It will weaken with the outflow from the convection.

I would say, as an amateur, looking better than before but still not good.

16.7/57 is about where I see it. I see some eastward moving clouds in the hi-res...but these look like they are at about 2-4K feet. Who knows what is going on at the sfc...but probably not all the way down...

Re: ATL : INVEST 94L
looks like that shear hasnt panned out as thought. Im going to go against the grain here. If it looks good, walks good, and talks good. Its in good shape. IMO appears to be developing

Recon will tell the truth guys.

Re: ATL : INVEST 94L
Beautiful upper outflow - which probably explains last night's IR presentation. The shear and anti-cyclone aloft managed to get the best out of a weak feature:
