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 cold front extends from near Naples, Florida to Merida Mexico
to a 1014 mb low pressure area near 21N94W. This pattern will
support strong to near gale force winds over the far western
Gulf through Sun, briefly reaching gale force late Sun off
Veracruz. The low pressure will move rapidly toward the Carolina
coast Sun through Mon, dragging a reinforcing front across the
eastern Gulf Mon into Tue. Winds and seas diminish through mid
week as the cold front shifts southeast of the area and high
pressure builds over the northern Gulf. Looking ahead, southerly
return flow will increase over the northwest Gulf by Thu ahead
of the next cold front.
...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...
Fresh to occasionally strong trade winds will pule off Colombia
through Sun, then diminish as high pressure north of the area
weakens and shifts east ahead of an approaching cold front. The
front will reach the Yucatan Channel Mon, extend from western
Cuba to eastern Honduras Tue, and stall from the Windward
Passage to northeast Nicaragua through mid week.
...SW N ATLANTIC INCLUDING THE BAHAMAS...
A cold front from 31N73W to Vero Beach, Florida will start to
stall and weaken from Bermuda to the Upper Florida Keys by
early Sun. The front will lift northward through late Sun ahead
of a stronger cold moving off the northeast Florida coast late
Sun night. The second front will reach from Bermuda to western
Cuba Tue, and from 25N65W to the Windward Passage through mid
