Marine Weather Discussion for the Gulf of Mexico, Caribbean Sea,
and Tropical North Atlantic from 07N to 19N between 55W and 64W
and the Southwest North Atlantic including the Bahamas

...GULF OF MEXICO...

As of 1800 UTC, a cold front extends from northern Florida near
29N83W to 22N90W where it becomes stationary, then continues to
21N96W to 18N95W. An area of showers and tstms is ahead of the
front affecting the SE Gulf waters. Winds and seas could be
higher near tstms. The front will reach from SW Florida to the
Bay of Campeche tonight, then move slowly across the SE Gulf on
Wed, exiting the area by late Wed. Minimal gale conditions are
forecast over the SW Gulf waters near Veracruz, Mexico late this
afternoon through Thu, with building seas of 11 or 12 ft.
Strengthening high pressure in the wake of the front will bring
an increase in winds and seas across much of the Gulf region Wed
evening into Thu, with these conditions shifting across the E
Gulf on Fri and Sat as the high pressure also shifts eastward
towards the Carolinas early on Fri. Looking ahead, a low
pressure system is forecast to develop over the north-central or
NE Gulf during the upcoming weekend, then move NE across
northern Florida into the Atlantic Ocean late on Sun. This
system may produce minimal gale conditions.

...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...

Strong to minimal gale force trade winds are forecast along the
the NW coast of Colombia during the overnight and early morning
hours through Sun. A cold front currently located over the Gulf
of Mexico will move slowly SE entering the NW Caribbean by late
Wed, then stall and gradually dissipate from Central Cuba to
Northern Belize on Thu. Strengthening high pressure in the wake
of the front will produce fresh to strong NE-E winds across the
basin, including the Atlantic passages Thu evening through Sat.
Seas are forecast to build to 12-14 ft across the south-central
Caribbean Fri night into Sat. Moderate to fresh trades will
continue across the tropical Atlc waters E of the Windwards
through Fri, with fresh to strong NE winds forecast on Fri night
through Sat night.

...SW N ATLANTIC INCLUDING THE BAHAMAS...

A cold front moving off the NE Florida coast this afternoon,
will reach a position from 31N70W to the Straits of Florida late
Wed, from 31N65W to Central Cuba late Thu, from 24N65W to along
the coast of central Cuba late Fri, then stall E to W along 22N
Fri night through Sat night while dissipating. Strengthening high
pressure in the wake of this front will produce strong to near
gale force NE-E winds W of the front Thu through Sat. The
strongest winds are expected S of 27N Fri and Sat, with building
seas of 12-14 ft E of the Bahamas.
