Two comments from the satellite presentations of these two systems today:
The GOM is certainly at the least a very broad elipitical area of low pressure, but there may be a little tightening up in the eastern side of that elipises, to the SW of Apalachecola. Just something to watch. The forecast is for higher pressure in the Bahamas to exert over the entire eastern gulf in the next 36 hours so this thing may get pushed on shore before it really starts.
The Carribean system is much better organized and has grown since daylight. It seems to be grabbing moisture from the SE behind it and if so that is a sure sign of development. I guess the issue with this is no clear LLC, or stacking of an LLC with the midlevel, which is what was occurring a couple of days ago. I still don't see any reason why this won't be a storm before it plays out. trajectory seems to be WNW to Central America.
