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

.SYNOPSIS...Fresh to strong northeast to east winds will
continue near the coast of Colombia through Sat night, then
diminish to moderate to fresh Sun and Sun night. Moderate to
fresh trades are expected elsewhere over the east and central
Caribbean while gentle to moderate winds will prevail over the
NW Caribbean. Fresh to strong southeast to south winds will
develop in the northwest Caribbean and in the Yucatan Channel by
early Fri as low pressure and its attendant cold front move
across the Gulf of Mexico. This front will likely reach the
Yucatan Channel and the far northwestern Caribbean on Sat
afternoon, then gradually weaken as it moves across the rest of
the northwest Caribbean through the weekend, eventually stalling
and dissipating. Fresh southeast winds will develop over most of
the western Caribbean Mon and Mon night, with the exception of
fresh to strong winds near the northeast coast of Honduras.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extends from near 31N54W southwestward 
to 23N61W, where it transitions to a stationary front to northern
Hispaniola. By Fri morning, the northern part of the front will 
shift E of the area, while the southern part will remain nearly 
stationary along the northern coast of Hispaniola. The front will
dissipate E of the area on Sat. High pressure in the wake of the
front will quickly move eastward through Fri night, allowing for
fresh to strong southerly winds to develop E of Florida as low 
pressure tracks northeastward from the Gulf of Mexico to inland 
the southeastern U.S. Fri night into Sat. These winds will expand
in coverage ahead the trailing cold front over the western 
waters. The front will reach from near 31N69W to the Windward 
Passage by late Sun night, and from near 31N64W to near the 
Virgin Islands by late Mon night. Gale conditions are expected 
over most of the northern and central zones with the southerly 
winds Fri through Sat. Strong to near gale force northeast winds 
and rough seas will follow this front.
