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

.SYNOPSIS...A 1021 mb high pressure north of the area supports
moderate to fresh easterly trade winds over much of the
Caribbean basin. Fresh to strong winds are pulsing in the
offshore waters of southern Hispaniola and in the Windward
Passage. The ridge is expected to slide eastward and weaken some
over the next few days, resulting in mainly gentle to moderate
trade winds through the week and into the weekend. Northerly
swell will support rough seas through the the NE Caribbean
passages until Wed.

Synopsis for the the SW N Atlantic including the Bahamas

strong SW to W winds and seas up to 10 ft are affecting the
waters N of 28N 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 slowly weakening. 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.
