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

.SYNOPSIS...A moderate pressure gradient between weak high
pressure centered north of the Greater Antilles and lower
pressures in northern South America will sustain moderate to
fresh easterly trade winds and moderate seas over the central
and eastern Caribbean through the middle of next week. Moderate
or lighter winds and slight to moderate seas will prevail
elsewhere. A persistent E-NE swell will support rough seas in
the Atlantic passages of the Lesser Antilles through the
forecast period. Looking ahead, a weakening cold front may
approach the northwestern Caribbean on Tue and linger across the
area through Wed. High pressure will build in by the middle of
next week, leading to strong winds and rough seas in the south-
central Caribbean into late next week.
