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 cold front extends from southeast Louisiana to northeast Mexico. Latest satellite derived winds and seas along with ship,buoy,and CMAN data depict fresh to strong winds over the northeast Gulf, with moderate to fresh winds prevailing elsewhere over the Gulf waters. The cold front will continue to shift eastward over the next couple of days, stalling over the southeast Gulf on Friday. Active convection will prevail well ahead of the front. High pressure will build in the wake of the front and prevail through the weekend.


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

A high pressure ridge extends across the southwest north Atlantic waters. Latest satellite derived winds and seas along with ship,buoy,and CMAN data depict fresh to strong winds over the central Caribbean, moderate to fresh winds over the remainder of the Caribbean, and gentle to moderate winds over the tropical north Atlantic. Seas are in the 7-9 ft range over the central Caribbean, 4-6 ft over the remainder of the Caribbean, and 5-6 ft over the tropical north Atlantic waters. High pressure will shift closer to the area through Thursday before retreating eastward through the weekend. This will bring an increase in winds and seas over the central Caribbean waters through the end of the week before decreasing through the weekend.


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

High pressure prevails over the forecast waters. Latest satellite derived winds and seas along with ship,buoy,and CMAN data depict fresh to strong winds over the northwest waters, moderate to fresh winds over the remainder of the northern waters and moderate winds prevail over the southern waters. The ridge will shift southward through Thursday then retreat eastward Friday. This will enable a cold front to move into the northwest waters Thursday morning. Near gale winds will prevail east of the front tonight into Thursday, where the pressure gradient is tightest between the front and surface ridge. The northern part of the cold front will shift eastward, moving east of the area by Saturday. The southern part of the front will stall across the northern Bahamas Friday and gradually dissipate through Saturday. High pressure will build in the wake of the front this weekend.
