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

.SYNOPSIS...High pressure across the western Atlantic extending
a ridge southwestward into the NW Bahamas will continue to
support strong NE to E winds offshore of Colombia and NW
Venezuela, while fresh trades will prevail E of 80W through Thu.
The high pressure will then slide SE and across the central
Atlantic subtropical waters Thu through the weekend, which will
keep mainly moderate to fresh trades across the central and
eastern Caribbean through Fri night, and gentle to moderate
easterly winds through the weekend. Fresh trades and moderate to
rough seas in easterly trade wind swell will prevail over the
tropical Atlantic waters and passages through Sat night.
Otherwise, pulsing fresh to strong E winds will develop each
night across the Gulf of Honduras from tonight through the
weekend.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...High pressure across the NW Atlantic extends a ridge
southwestward to the NW Bahamas, while the remnants of a frontal
trough persist offshore of Florida along 77W. This pattern is
producing moderate to fresh trade winds S of 25N and E of 77W,
while light to moderate SE winds prevail elsewhere. The high
will slide SE and into the central Atlantic through the upcoming
weekend, with ridging extending westward into central Florida.
This will gradually lead to anticyclonic winds across the entire
area by the weekend. Moderate to fresh trade winds and rough seas
in mixed NE and E swell will prevail south of 22N this week,
including across the Atlantic passages into the eastern
Caribbean.
