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

1. Disorganized cloudiness and thunderstorms over the western Caribbean
Sea 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...low...30 percent.
* Formation chance through 5 days...medium...40 percent.
