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 Gulf waters. Latest
satellite derived winds and seas along with ship, buoy, and CMAN
data depict light and variable winds over the northern Gulf with
light to gentle winds prevailing over the southern Gulf. Seas are
in the 2-4 ft range over the southwest Gulf and 1-2 ft elsewhere. 
High pressure will prevail over the northern waters through the
week. A thermal trough will develop each evening over the 
Yucatan Peninsula before pushing offshore into the SW Gulf each 
night, where it will dissipate each morning. A surge of moderate
to fresh N-NE winds will accompany this trough, with seas 
briefly peaking at 5 ft in association with these winds. 
Otherwise, gentle to moderate E to SE winds and seas of 4 ft or 
less will continue over most of the Gulf through the forecast 
period.
   
...CARIBBEAN SEA AND TROPICAL N ATLANTIC FROM 07N TO 19N BETWEEN
55W AND 64W...

A ridge of high pressure prevails north of the area. Latest 
satellite derived winds and seas along with ship, buoy, and CMAN 
data depict fresh to strong winds over the south central 
Caribbean, moderate to fresh winds over the north central 
Caribbean. Gentle to moderate winds prevail over the remainder 
of the Caribbean as well as the tropical north Atlantic forecast 
zones. Seas are in the 5-8 ft range over the central Caribbean, 
3-5 ft over the eastern and western Caribbean, and 4-5 ft over 
the tropical north Atlantic forecast zones. The ridge to the 
north of the area will weaken, which will reduce the pressure 
gradient and decrease winds and seas by the middle of this week.

..SW N ATLANTIC INCLUDING THE BAHAMAS...

High pressure prevails over the forecast waters, while the
remnants of Tropical Depression Four are moving into the
southeast waters. Latest satellite derived winds and seas along 
with ship, buoy, and CMAN data depict light to gentle winds over 
the waters north of 25N and gentle to moderate winds south of 
25N. Seas are in the 3-4 ft range over the northern waters, 4-6 
ft over the southern waters outside the Bahamas, and 1-3 ft west 
of the Bahamas. The ridge over the forecast waters will shift 
northward as the remnants of Tropical Depression Four move across
the forecast area through midweek.
