...GULF OF MEXICO...

A cold front extends southwest from north Florida to 24N96W then 
is stalling south to Veracruz Mexico.  The front will weaken 
across the southern gulf waters this afternoon, and then 
gradually dissipate tonight into Fri. A ridge will extend from 
the Florida Big Bend to southern Texas on Fri, then retract east 
on Fri night in advance of a second cold front entering the far 
northwest waters late Fri night. This second front will stall 
from southwest Florida to Veracruz Mexico on Sun, with remnants 
of the front lifting rapidly northeast on Sun night and Mon as a 
third cold front reaches the northern coastal waters. Further 
south, a thermal trough will develop over the Yucatan Peninsula 
during the afternoons, drift west across the eastern Bay of 
Campeche during the overnight hours, and dissipate over the 
southwest gulf waters by late each morning.  

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

Fresh to locally strong nocturnal trades will continue along the 
northwest coast of Colombia through Mon night. Fresh to locally 
strong easterly trades are forecast to resume across the Gulf of 
Honduras on Sat night. Otherwise, gentle to moderate trades are 
forecast elsewhere through Mon night.

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

A ridge from Bermuda to Fort Pierce Florida will continue to 
retract east today allowing a cold front to enter the far 
northwest waters. The cold front will extend from Bermuda to the 
Bahama Channel this evening, then stall from 28N65W to the 
northern Bahamas on Fri, and gradually dissipate through Sat as 
a ridge redevelops from Bermuda to central Florida. Fresh to 
locally strong southerly flow forecast north of the ridge on Sat 
ahead of a second cold front moving into the northwest waters on 
Sat night. This cold front will reach from 30N65W to the 
northern Bahamas on Sun night, then stall along 26N on Mon with
