I just looked at the visibles for 93L. If you hit the "NWS Fronts" box it almost appears that this system is *trying* to get itself together tonight. Yes, it's true that all the convection is to the north and east of it, but Tammy didn't look all that great yesterday either. My eyes may be deceiving me, but it also appears that it's trying to work itself down to the surface.
Please keep in mind that I am not predicting that a major hurricane will hit the west coast of Florida this weekend...no alarm sirens going off with this post. However, I wouldn't be surprised if this becomes classified as a T.D. before hitting land. I think people (besides us) who hear "a tropical depression" think "Ah, well, no biggie". They forget that even a tropical low or a tropical depression can cause major problems with rains and flooding.
And after the way this hurricane season has gone, anything is possible.
