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 into the NW Bahamas will continue to support strong NE
to E winds offshore Colombia, and fresh trades elsewhere E of
80W through tonight. The high pressure will then slide E-SE and
across the central Atlantic subtropical waters through the
weekend, which will keep mainly moderate to fresh trades across
the central and eastern Caribbean tonight through Thu night, and
gentle to moderate easterly winds the remainder of the forecast
period. Moderate to 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 are forecast in 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 78W-79W. This pattern
is producing moderate to fresh trade winds S of 25N and E of
65W, and moderate to fresh SE to S return flow between 65W and
75W. The high will slide E-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. Pulsing fresh E
winds are expected each afternoon and evening offshore of
northern Hispaniola through Fri. Moderate to fresh trade winds
and rough seas in mixed NE and SE swell will prevail south of 25N
this week, including across the Atlantic passages into the
eastern Caribbean.
