...GULF OF AMERICA...
A tight pressure gradient prevails over the SW Gulf supporting
strong to near gale force winds, and seas of 8-12 ft. Fresh to
strong winds, and seas of 8-11 ft, prevail elsewhere S of 24N.
Moderate to fresh winds, and seas of 6-7 ft, prevail N of 24N.=20

the west- central and SW Gulf on Fri and linger through Sat night=20
while weakening. Low pressure will develop along the trough on Sat
near South Texas, then track NE through Sun night before=20
weakening through Sun night. The low will drag a frontal boundary=20
southeastward to just southeast of the basin by late Tue. Moderate
to fresh winds are expected behind the boundary as weak high=20
pressure builds over the NW Gulf.=20
...CARIBBEAN SEA...
A frontal boundary is over the NW waters. Fresh winds, and seas of
6-7 ft prevail W of the front. Strong to near gale winds are off
the coast of Colombia, with seas of 8-9 ft. Strong winds are in
the gulf of Venezuela. Elsewhere, moderate to fresh winds, and

rough seas offshore of Colombia and within and near the Gulf of=20
Venezuela. A stationary front over the NW Caribbean will gradually
dissipate by this weekend. Strong high pressure building in the=20
wake of the front will bring fresh to strong NE winds in the Lee=20
of Cuba and the Windward Passage this evening through early Sun.=20
Otherwise, rough seas in east swell will continue east of the=20
Lesser Antilles through Sat, subsiding afterward.=20
