Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. Synopsis for Caribbean Sea and Tropical N Atlantic from 07N to 19N W of 55W .SYNOPSIS...A cold front moving through the SE Gulf of Mexico and W Cuba will move into the NW Caribbean and stall today, before dissipating Fri. High pressure building north of the area behind the front will support fresh NE winds across the basin late today, with locally strong winds pulsing offshore of Colombia. Fresh to strong NE winds and accompanying rough seas will occur across the northwestern and north-central Caribbean on Sat, ahead of another front moving through the western Atlantic and eastern Gulf of Mexico. Looking ahead, the winds and seas will diminish Sun into Mon as the high pressure shifts eastward ahead of the next cold front moving through the Gulf of Mexico.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from SE of Bermuda to western Cuba will weaken as it moves eastward today, reaching a position from 31N60W to central Cuba by this evening. The front will stall and dissipate through late Fri, ahead of a reinforcing cold front expected to move off the NE Florida coast late Fri. Strong to near-gale force winds and rough seas will accompany the front mainly north of 26N Fri night, likely reaching gale force with very rough seas early Sat morning through Sat evening over the offshore waters between 60W and 75W. Winds will further diminish Sun in most areas as high pressure builds eastward behind the front as it exits to the east of region. Looking ahead, fresh to strong southerly winds will return to the waters off NE Florida and north of the Bahamas Sun night into Mon ahead of the next cold front expected to move off the coast by late Mon.
