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...

Strong NW winds, with frequent gusts to gale force, are expected over the north-central and NE parts of the Gulf this morning, diminishing to 20-25 kt in the afternoon as high pressure continues to build across the basin. Associated seas will gradually subside. The high pressure will support generally tranquil marine conditions across the basin Sun into Mon, then will shift east of the area early next week. This pattern will support increased winds and seas over the northwest Gulf Mon and Tue between the high pressure and lower pressure farther west over Texas, before diminishing through mid week.


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

A cold front extending across the northwest Caribbean will stall from eastern Cuba to the Gulf of Honduras tonight, then dissipate through Mon. High pressure building in the wake of the front north of the region will support the expansion of fresh to strong trade winds and building seas from off Colombia to cover most of the south-central and southwest Caribbean from Sun through Wed night. These winds may pulse to gale force mainly at night off Colombia starting Tue night.


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

A cold front extending from 31N74W to western Cuba will reach from Bermuda to eastern Cuba tonight, before stalling from 26N65W to eastern Cuba by late Sun and dissipating early Mon. Another cold front will move into the waters between northeast Florida and Bermuda late Sun, and also stall from 26N65W to eastern Cuba by Mon night and early Tue, before dissipating through mid week.
