from 07N to 19N W of 55W, the N Atlantic from 19N to
31N W of 55W including the Bahamas, and the Caribbean Sea.

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

.SYNOPSIS...Broad high pressure located between Bermuda and the
Bahamas will support fresh to locally strong trade winds in the
lee of Cuba and Windward Passage at night during the next few
days. These winds will gradually diminish this weekend into
early next week as a cold front moves across the western
Atlantic and the pressure gradient relaxes. High pressure that
will build in behind the front is expected to support fresh to
locally strong trade winds in the south-central Caribbean
starting Mon.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...Low pressure just E of 55W extends a trough through
24N55W to near the NE Caribbean islands. Otherwise high pressure
dominates the basin. The low and trough will shift ESE through the
end of the week. High pressure will then prevail through the
weekend with mainly gentle to moderate winds. A cold front may 
move into the waters off NE Florida early Mon, reaching from 
31N70W to the northern Bahamas early Tue. Moderate to fresh winds
may accompany the front. Winds may freshen over the SE waters 
next week as the pressure gradient tightens there leading to 
building seas. Mainly slight to moderate seas will prevail 
elsewhere.
