Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...An Atlantic high pressure ridge along 26N will help
sustain fresh trade winds across the central Caribbean through
Wed, then become strong Wed night through Sat as high pressure
reorganizes NE of the Bahamas. The coverage area of these winds
is expected to diminish beginning Sat night. Winds will pulse to
gale-force off the coast of Colombia each night through Sat.
Fresh to strong NE to E winds will also occur in the Windward
Passage and lee of Cuba Wed through Sun night. Fresh to strong
SE winds will pulse nightly across the Gulf of Honduras tonight
through Fri night. Fresh to strong SE winds will begin in the
Yucatan Channel tonight and last through Thu night.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...An E to W ridge axis along 26N will weaken through 
tonight, then reorganize NE of the Bahamas Wed. Fresh to strong
SW to W winds across the northern waters should continue through
early Wed as a frontal system sweeps eastward across the NW 
Atlantic. The western end of that front will move southeastward 
across the NE forecast waters Wed afternoon and night, and reach
along 22N late Thu. High pressure behind the front will act to 
freshen NE to E trade winds south of 24N during this period. 
Looking ahead, large NW swell and near gale-force NW winds are 
possible on Sat across the NE waters associated with another
cold front. The southern part of a cold front will brush the NE 
forecast waters Sun and Sun night. Otherwise, rather quiet 
conditions are expected Sun and Sun night as high pressure 
settles in over the area.
