As far as the West Caribbean:

From Houston:
The Nam/Gfs/Ecmwf Are All Working A
Tropical Wave into a Tizzy in the Western Caribbean on Monday
Unfortunately the Same Upper Ridging Should Be Flattening And
Shifting East Opening Up the Western Gulf to This Wave/Tropical
System. Interestingly the 00z Ecmwf Looks Like the 18z Gfs Which
Has It Nearing the Texas Coast Friday the 9th. It is Still To
Early to Hang a Hat on This Solution but Should Still Point to The
Possibility of Something of Interest in the Western Gulf. Rain
Chances Should Be Coming Down Monday and Tuesday as Moisture Thins
And Upper Ridging Creeps Southward.
