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 Ft Myers, FL to the central Bay of 
Campeche. Recent scatterometer and surface data show fresh to 
strong NE winds north of the front. Although 30 kt winds are
still likely near the Veracruz coast of Mexico overnight, model 
guidance no longer shows gale force winds, and the gale warning 
for this area of the Gulf has been discontinued. The front will
reach from the Florida Keys to the Yucatan peninsula later today
then move SE of the Gulf tonight. Southerly return flow ahead of
the next cold front will increase across the NW Gulf on Fri, and
strengthen Fri night as a low pressure system develops over SE
Texas. This low will track eastward along the U.S. gulf coast
this weekend, with strong S to SW winds expected ahead of the
cold front. Model guidance is in good agreement with the synoptic 
feature, and indicate 30 kt winds are likely in the northern Gulf
and its coastal waters Sat and Sun.

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

Scatterometer data shows fresh to strong E-NE winds in the south-
central Caribbean, with the strongest winds along the coast of 
Colombia near 12N75W. A cold front in the Gulf of Mexico will 
reach the NW Caribbean late tonight, then stall and weaken from 
eastern Cuba to northern Honduras on Thu. Winds will diminish 
somewhat in the south-central Caribbean today as the front moves 
closer. Building high pressure north of the area late Thu through
Sat will allow fresh to strong winds to redevelop near Colombia.
Also expect fresh to strong NE winds south of Cuba overnight. 
Moderate to fresh trades will continue E of the Lesser Antilles 
through the weekend. 

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

A cold front extending across the forecast area from 31N69W to 
Palm Beach FL will reach from 30N65W across the Bahamas to 
northern Cuba tonight. Reinforcing cold air will support fresh 
N-NW winds behind the front through Thu morning. The front will 
stall and weaken Thu night through Sat. A developing low pressure 
system across the southern U.S. will drag a strong cold front off
the coast of northern Florida on Sun. Model guidance shows strong
to near-gale southerly winds ahead of the front Sat night and 
Sun, with the strongest winds expected to be north of 28N.
