from 07N to 22N between 55W and 64W, the SW N Atlantic S of
31N W of 65W including Bahamas, and the Caribbean Sea.

Seas given as significant wave height, which is the average

Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...The gradient between high pressure north of the
region and relatively lower pressure in NW Colombia will allow
for strong to near gale-force northeast winds to pulse off the
coast of Colombia at night through Sun night. Fresh to strong
east to southeast winds in the Gulf of Honduras will diminish to
fresh speeds by early this afternoon. Otherwise, the tail of a
cold front will move into the NW Caribbean Thu morning, and
extend from central Cuba southwestward to northern Belize
adjacent waters by Thu evening. Moderate to fresh northerly
winds will follow in behind the front.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...High pressure over the region will continue to shift
eastward today as a strong cold front approaches from the west. 
The cold front will move off the northeast Florida coast this 
afternoon, reach from near 31N72W to the NW Bahamas and to 
western Cuba early Thu, from near 31N67W to central Cuba Thu 
evening, then across the eastern part of the area through late 
Sat. Gale-force southerly winds are expected ahead of the front 
mainly north of about 30N today and tonight. Increasing gusty 
winds along with building seas are expected elsewhere ahead and 
behind the front north of 26N through Thu evening. Showers and 
thunderstorms in a line, some strong to occasionally severe, are 
expected to precede the front. Otherwise, a couple of weaker cold
fronts will sweep across the northern waters Fri through Sun 
night, followed by fresh to strong west to northwest winds.
