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

.SYNOPSIS...A cold front extends from central Cuba to eastern
Honduras. Fresh to strong winds and rough seas will continue to
follow the front across the W Caribbean today. Winds and seas
will diminish this afternoon. High pressure building north of
the region in the wake of the front will support fresh to strong
NE winds in the lee of eastern Cuba and across the Windward
Passage tonight through Sat evening. Winds and seas will then
diminish by Sat night. Moderate N swell moving through the NE
Caribbean Passages and adjacent Tropical Atlantic waters will
gradually subside through today. Strong trade winds and rough
seas will pulse off the coast of Colombia and the southern coast
of Hispaniola this weekend as the high pressure settles NE of
the Bahamas.
