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 pres centered over Texas extends SE to the NW Caribbean, 
and will dominate the Gulf region through Mon as the high slides
slowly E. This pattern will produce mainly a moderate to locally
fresh wind flow, except off the W coast of the Yucatan Peninsula
where late evening local effects will produce brief periods of 
NE winds to 25 kt. 

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

Low pressure N of the area with associated cold front extending
to the NW Caribbean is allowing for a relaxed pressure gradient 
in the south-central Caribbean. However, fresh to strong winds 
are expected to pulse at night within 60 nm off the coast of 
Colombia. The cold front, currently extending from the coast of
Cuba near 20N78W to the coast of NE Honduras, will stall this
morning and gradually weaken through late tonight when it is
forecast to dissipate. Gentle to moderate winds will dominate 
across the remainder of the basin through Mon. 

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

A stationary front extends from 30N65W to a 1009 mb low pressure
centered near 29N68W then continues as a cold front to the
southern Bahamas to Cuba near 21N77W. Strong to gale force winds
are occurring in the NW semicircle of the low and will continue 
through this morning as the low shifts NE. The low will dissipate
tonight NE of the area and the front will stall. However, a 
reinforcing cold front will merge with the stationary front on 
Fri and move E of the area by Sun morning. Swell generated by 
these fronts will dominate the waters E of the Bahamas through 
the upcoming weekend.
