800 AM EDT Thu Oct 26 2017

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

1. A broad area of low pressure located over the western Caribbean Sea
and Central America continues to produce disorganized showers and
thunderstorms. Close proximity to land is likely to limit
development of this system during the next 24 hours. However,
environmental conditions are expected to be conducive for the system
to become more organized Friday and Saturday as it 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 portions of Central
America and Cuba during the next couple of days. These rains are
forecast to spread northward across portions of South Florida and
the Keys on Saturday.
* Formation chance through 48 hours…low…30 percent.
* Formation chance through 5 days…medium…40 percent.
