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 stationary front from southwest Florida to the eastern Bay of Campeche will slowly dissipate tonight and early Fri. A reinforcing cold front will move through the northeast Gulf Fri, eventually stalling across South Florida and the southeast Gulf through late Sat. Meanwhile, developing low pressure over the northwest Caribbean and Yucatan peninsula will support strong to near gale force winds and blading seas over the mainly the south central Gulf from late Fri to early next week.


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

Environmental conditions are forecast to be conducive for low pressure to develop along a tropical wave moving through the northwest Caribbean, and a tropical depression could form over the weekend. This pattern will support fresh to strong winds over the parts of the eastern and central Caribbean between the low pressure and high pressure over the central Atlantic.


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

A stationary front from extending from 31N75W to W Palm Beach Florida will gradually dissipate through Fri. A reinforcing cold front will move into the waters off northeast Florida late Fri and early Sat, before also stalling from near 31N75W to South Florida by late Sat and dissipating through Sun. Meanwhile high pressure over the central Atlantic lower pressure in the northwest Caribbean will support moderate to fresh trades winds south of 20N, occasionally pulsing to strong winds north of Hispaniola during the overnight hours. Looking ahead, a third weak front will move south and stall from 31N72W to Central Florida by Mon night.
