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 nearly stationary front extends from 24N83W to 28N93W to
1014 mb low pres centered near 27N95W to the Bay of Campeche
near 19N95W. The low pressure will lift N toward the coast of 
Texas through Wed night, then ENE across the N central waters 
through Thu night, moving over the NE Gulf over N Florida by Fri.
The developing low will drag a new cold front across the Gulf 
waters. The next cold front will arrive on the northern Gulf 
coast by Sun morning.

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

Gentle to moderate trades will prevail across the Caribbean Sea 
during the next several days, with the exception of light to 
gentle winds over the NW Caribbean. By Sat night, winds are 
expected to become fresh across the south-central Caribbean. A 
tropical wave extending from the Dominican Republic to eastern 
Venezuela will become a trough today, then finally weaken and 
dissipate by Thu. The first cold front of the season will enter 
the NW Caribbean Sat night, then stall Sun.

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

A nearly stationary front extends from 26N65W to 23N77W to the 
Straits of Florida. Fresh to strong winds and seas as high as 10 
ft are observed in the wake of the front E of the Bahamas. The 
front will weaken tonight and Wed and allow winds and seas to 
decrease. The pressure gradient between high pressure over the NE
United States and low pressure tracking NE from the Gulf of 
Mexico across northern Florida will cause winds and seas east of 
NE Florida to increase Thu and Fri. As the low tracks toward the 
NE United States, the trailing cold front will head SE from 
Florida Sat, then reach the NW Bahamas Sat night. The front will 
then stall and weaken Sun and Sun night.
