Looks like now the 06Z GFS has latched onto a closed low developing in the central Bahamas and drifting west to the gold coast, across S FL, and then further developing in the SE GOM. That makes it nearly unanimous among the global models (includes 00Z Euro) in developing a depression or TS and slowly drfting it west into the GOM. If you believe the GFS, it will take this low 72 hours to go from offshore Ft Laud to offshore Ft Meyers in the Thur-Sun time frame. Wow, looks like a major rain event if nothing else.
