For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. Cloudiness and thunderstorms extending from northern Nicaragua and
eastern Honduras northeastward across the Cayman Islands and Jamaica
to eastern Cuba are associated with a trough of low pressure.
Environmental conditions are expected to be conducive for some
development on Friday and Saturday as the system moves slowly
northward over the northwestern Caribbean Sea.  Strong upper-level
winds associated with an approaching cold front will make conditions
less favorable by Sunday.   Regardless of development, this system
is expected to produce locally heavy rainfall over the Cayman
Islands, Jamaica, and portions of Cuba during the next day or two.
These rains are forecast to spread northward across portions of
South Florida and the Keys on Saturday, and over the northwestern
Bahamas Saturday night and Sunday.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.
