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

.SYNOPSIS...Moderate to fresh trade winds and moderate seas will
prevail over most of the central and eastern Caribbean through
Mon night, except for strong to near gale-force winds and rough
seas offshore of Colombia and within and near the Gulf of
Venezuela. Winds off Colombia will pulse to gale-force tonight
and Sat night. A cold front front over the NW Caribbean will
stall and gradually dissipate by this weekend. Strong high
pressure building in the wake of the front will bring fresh to
strong NE winds in the Lee of Cuba and the Windward Passage this
evening through early Sun. Otherwise, rough seas in east swell
will continue east of the Lesser Antilles through Sat, subsiding
afterward.

Synopsis for the the SW N Atlantic including the Bahamas

.SYNOPSIS...A cold front extends from near 31N60W southwestward
to 26N71W and to central Cuba. The front will weaken as it
reaches from near 26N55W to 24N60W, continuing as a stationary
front to Haiti Sat night and dissipating soon afterward. Its
remnant trough will drift back west toward the southeastern
Bahamas through Mon while dissipating. Strong high pressure in
the wake of the front will lead to fresh to strong northeast
winds south of 25N, including the Straits of Florida and the
Great Bahama Bank Fri night into Sat night. Conditions improve
Sun into early Mon. Later during Mon, low pressure from the Gulf
will approach central or southern Florida, and quickly track NE
through late Tue dragging a frontal boundary across the western
part of the area. Fresh to near gale strong southwest winds are
expected ahead of the low pressure and frontal boundary along
with building seas.
