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

.SYNOPSIS...A 1022 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 1022 mb high pressure system located between
Bermuda and the Bahamas dominates the SW N Atlantic. Moderate to
fresh W winds and long period northerly swell with peak seas
near 12 ft are affecting the waters N of 29N and E of 65W. These
marine conditions will slide eastward as a cold front reaches
the NE waters later today. Moderate to fresh 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.
