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...

Fresh to strong SE flow will spread from the northwest Gulf across the basin today, ahead of a cold front moving off the Texas coast tonight. Strong NW winds will follow the front, reaching gale force over the western Gulf Wed. Winds and seas diminish across the Gulf Thu as the front moves southeast of the region. Looking ahead, SE flow will increase again Sat ahead of another front moving off the Texas coast Sat night.


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

A stalled and weakening frontal boundary from the Windward Passage to eastern Honduras will dissipate today. Strong high pressure north of the area behind the front will maintain strong NE winds over much of the Caribbean through mid week, with gales pulsing off Colombia. Winds and seas will diminish late in the week as the high pressure shifts east ahead of another cold front expected to move into the northwest Caribbean by late Thu. The second front will stall then dissipate from central Cuba to central Honduras by late Fri. Looking ahead, a third front will enter the northwest Caribbean Sun and reach from western Cuba to the Gulf of Honduras Sun night. Farther east, NW swell will move into Atlc waters off the Leeward Islands by Wed night.


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

A cold front extending from near 25N65W to the Windward Passage will become stationary from north of Puerto Rico to near the Windward Passage late today then dissipate through Thu. High pressure building north of the area in the wake of the front will support fresh to strong winds through mid week. Strong southerly winds will develop off northeast Florida by Thu ahead of another cold front, reaching gale force north of 30N. Winds and seas will diminish through late week as the front continues east, stalling and weakening from Bermuda to eastern Cuba by Sat. Looking ahead, a weak disturbance will form along the front Sun in the northern Bahamas and move northeast.
