Synopsis for Caribbean Sea and Tropical N Atlantic from

.SYNOPSIS...The gradient between high pressure north of the
region and relatively lower pressure in NW Colombia will allow
for strong to near gale-force NE winds off the coast of Colombia
through early Wed morning. These winds will then pulse to strong
speeds at night starting Wed night and continuing through Sun
night. Fresh to near gale-force E to SE winds in the Gulf of
Honduras will diminish to fresh speeds late Wed morning. The
tail of a cold front will move into the NW Caribbean Thu morning
and extend from central Cuba SW to the northern Belize adjacent
waters by Thu evening.
