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

.SYNOPSIS...A moderate pressure gradient between a weak Atlantic
ridge along 26N, 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
across the Atlantic waters and passages of the Lesser Antilles
through next Thu. Looking ahead, a weakening cold front will
approach the northwestern Caribbean on Tue and linger across the
Yucatan Channel and Straits of Florida through Wed. High
pressure will build across the eastern Gulf of America by the
middle of next week, leading to strong winds and rough seas in
the south-central Caribbean into late next week.
