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...

A few showers and thunderstorms are ongoing over the southeast
Gulf ahead of a cold front reaching from the Florida Big Bend 
area to the central coast of Texas. The showers and thunderstorms
will weaken and shift eastward through the early morning.
Platforms over the northwest Gulf are reporting areas of fog with
visibilities around 4 nm. This will clear up later this morning
as drier air filters into the region behind the front. Seas are 3
to 5 ft across the region. The front will continue to move south
before stalling from South Florida to South Texas later today. 
The front will dissipate as it lifts northward over the western 
Gulf through early Tue, ahead of another cold front moving into 
the northwest Gulf late Wed. Fresh to strong northerly winds and 
seas building to 8 ft will follow the front mainly off the coast 
of Mexico as the front reaches a position from central Florida to
the southwest Gulf by late Thu before lifting northward over the
western Gulf and weakening Fri.


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

High pressure north of the area is supporting gale force winds
off the coast of Colombia, as verified by vessel 9HA3047
earlier. Seas are 8 to 11 ft over much of the south central and
southwest Caribbean, and generally 5 to 7 elsewhere in the 
Caribbean. Recent buoy observations over the tropical Atlantic
indicate NE to E swell and locally derived wind waves due to
fresh trade wind flow have reached the Leeward and Windward
Islands and may be pushing into exposed Atlantic passages. No 
significant convection is observed due to mainly zonal westerly 
flow aloft, but fast- moving trade wind showers are likely from 
the tropical north Atlantic west of 55W through the southwest 
Caribbean. The pattern will continue to support fresh to strong 
winds off Colombia, the Windward Passage and in the lee of 
Hispaniola through Fri, pulsing to gale force off Colombia each 
night. High pressure building over the central Atlc will continue
to support fresh trades east of the Leeward and Windward 
Islands, accompanied by NE to E swell in excess of 8 ft. 

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

A cold front is moving off the northeast Florida coast. Scattered
showers and a few thunderstorms are noted in advance of the
front, as are fresh to strong southerly flow north of 30N. Recent
buoy observations and altimeter satellite passes indicate 5 to 7
ft seas in open waters. The front will reach from Bermuda to 
South Florida by late today, stall from 29N65W to the Straights 
of Florida late Tue, then dissipate by mid week. High pressure 
will build behind the front, supporting fresh to occasionally 
strong E winds south of 22N by mid week.
