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...Moderate to fresh trade winds and moderate seas will continue over most sections of the central and eastern Caribbean through Mon night, except for strong to near gale-force winds and rough seas offshore of Colombia and within and near the Gulf of Venezuela. Gentle to moderate winds along with slight to moderate seas will prevail in the northwestern Caribbean through Thu night, then return Sat night through Mon night. A cold front will approach the Yucatan Channel Thu night, reach the Windward Passage Fri night into Sat before dissipating Sat night. Strong high pressure building in the wake of the front N of the area will lead to the development of fresh to strong NE winds in the Lee of Cuba and the Windward Passage Fri evening through early Sun. Otherwise, rough seas in east swell will continue east of the Lesser Antilles through Sat, subsiding afterward. NW Caribbean W of 85W .TONIGHT...E winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Fresh to strong winds will continue to affect the offshore waters N of 28N through Fri, ahead and behind of a cold front that extends from 31N77W SW to Cape Canaveral, Florida where it briefly stalls. The front will reach from near 31N75W to South Florida early Thu, from near 31N63W to 26N70W and to eastern Cuba early Fri, from near 29N55W to the Windward Passage Fri night, then begin to weaken as it reaches from near 26N55W to 22N64W to the Windward Passage Sat night. Strong high pressure will build Sat and Sat night in the wake of the front. The resultant tight gradient will bring fresh to strong northeast winds to the Straits of Florida and the Great Bahama Bank primarily south of 25N Fri night into Sat night. Conditions begin to improve beginning Sun as a second cold front moves across the NW part into early next week. ATLC waters from 27N to 31N W of 77W .TONIGHT...W winds 10 to 20 kt.
