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

.SYNOPSIS...A 1021 mb high pressure system north of the area
supports moderate to fresh easterly trade winds over much of the
Caribbean Sea. Fresh to locally strong winds are found in the
Gulf of Honduras, offshore southern Hispaniola and in the south-
central Caribbean near the coast of Colombia. The ridge is
expected to slide eastward and weaken some over the next few
days, resulting in mainly gentle to moderate trade winds midweek
and into the weekend. Northerly swell will support rough seas
through the passages in the NE Caribbean through Wed.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A 1021 mb high pressure system located between
Bermuda and the Bahamas dominates the SW N Atlantic. Fresh to
locally strong SW to W winds and seas up to 10 ft are affecting
the waters N of 29N and E of 60W. These marine conditions will
slide eastward as a cold front moves across the NE waters
tonight and Wed while weakening. Moderate to fresh easterly
winds will continue over the waters S of 22N and W of 60W through
Wed, including in the approaches of the Windward Passage. The
high pressure will move eastward while weakening some. A surface
trough may develop just N of Hispaniola over the next 48 hours
and move east toward the waters just north of Puerto Rico by the
end of the work week.
