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 high pressure ridge over the southeastern United States will 
maintain gentle to moderate E to SE winds and seas generally 3 
ft or less will generally prevail through the end of next week. 
A surface trough will develop over the Yucatan peninsula each 
evening, shift W over the SW gulf each night, then dissipate by 
morning. Moderate to fresh winds will accompany the trough. 

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

Tropical Depression Eleven near 13.1N 53.4W 1007 mb at 11 PM EDT
moving WNW at 5 kt. Maximum sustained winds 30 kt gusts 40 kt. 
Eleven will move to 13.5N 54.2W Sat morning, 13.8N 55.0W Sat 
evening, 14.2N 56.3W Sun morning, 14.5N 58.0W Sun evening, and 
dissipate Mon evening. Otherwise, fresh to strong winds prevail 
over the central Caribbean. These winds will diminish across most
of the basin by Sun night as low pres passing N of the Bahamas 
weakens the ridge over the western Atlc. Winds in this area will 
increase toward the end of next week as the ridge rebuilds. A 
vigorous tropical wave will cause winds and seas E of the 
Windward Islands to increase Tue night through Thu.

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

A weakening front extends from a 1010 mb low centered near 
30N64W to 27N68W. The front will dissipate by midday Saturday, 
while the low slowly drifts W across the northern forecast waters
through early next week. Deep low pressure over the central Atlc
will generate long period NE swell which will cause seas E of 
the Bahamas to build Wed night through Thu night.
