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... 

High pressure prevails over the northern waters. Latest
satellite derived winds and seas along with ship, buoy, and CMAN
data depict light winds over the northeast Gulf, moderate to
fresh winds over the southwest Gulf, and light to gentle winds
elsewhere. Seas are in the 1-3 ft range. High pressure will
prevail over the northern waters through the weekend. 

A thermal trough will develop over the Yucatan Peninsula each 
evening hours before pushing offshore into the SW Gulf each 
night. The trough will drift westward during the overnight 
hours, and dissipate over the SW Gulf each morning. 

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

The remnants of Tropical Storm Don are moving through the
southeast Caribbean waters, producing a small area of gale force
winds over this area. Elsewhere Fresh to strong winds prevail
over the central and eastern Caribbean, except off the coast of
Colombia where winds are reaching near gale force. Gentle to
moderate winds prevail over the western Caribbean, while moderate
to fresh winds prevail over the tropical north Atlantic forecast
zones. Seas are in the 10-12 ft range in the area of gale force 
winds associated with the remnants of Don. Elsewhere seas are in 
the 10-11 ft range off the coast of Colombia, 8-10 ft over the 
remainder of the central and eastern Caribbean, 4-5 ft over the 
western Caribbean, and 6-8 ft over the tropical north Atlantic 
forecast zones. The ridge north of the area will weaken by weeks 
end which will decrease coverage of the fresh to strong winds 
over the area. 

..SW N ATLANTIC INCLUDING THE BAHAMAS...

High pressure prevails over the forecast waters. Latest 
satellite derived winds and seas along with ship, buoy, and CMAN 
data depict moderate to fresh winds over the southern waters,
except to strong north of Hispaniola into the windward passage,
and light to gentle over the northern waters. Seas are in the 5-7
ft over the southern waters outside the Bahamas, 1-3 ft west of
the Bahamas, and 3-5 ft over the northern waters. High pressure
will prevail over the forecast waters through the remainder of
the week into the weekend. Pulsing fresh to locally strong winds
are expected just north of Hispaniola, including the approach to
the Windward Passage during the evenings through at least 
Friday.
