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. Strong speeds are found in the Gulf of Honduras,
offshore southern Hispaniola and the Windward Passage. The ridge
is expected to slide eastward and weaken over the next few days,
resulting in more tranquil marine conditions 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. Moderate to
locally strong W winds and long period northerly swell with peak
seas near 12 ft are affecting the waters N of 29N and E of 67W.
These winds and seas will slide eastward as a cold front enters
the northern waters this afternoon. Moderate to locally strong
easterly winds will continue over the waters S of 24N and W of
60W through Wed, especially in the approaches of the Windward
Passage. More tranquil marine conditions are expected afterwards
as high pressure becomes centered over the NW waters.
