000 FZNT31 KNHC 192010 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 410 PM EDT Fri Apr 19 2024 Marine Weather HF Voice Broadcast for the Tropical N Atlantic from 07N to 19N W of 55W, the N Atlantic from 19N to 31N W of 55W including the Bahamas, and the Caribbean Sea. 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...Broad high pressure located between Bermuda and the Bahamas will support fresh to locally strong trade winds in the lee of Cuba, Windward Passage, and south of the Dominican Republic at night during the next few days. These winds will gradually diminish this weekend into early next week as a cold front moves across the western Atlantic and the pressure gradient relaxes. A locally tight pressure gradient will support pulsing fresh to locally strong winds near northern Colombia at night through the period. A surface trough approaching the Windward Islands is accompanied by scattered showers and thunderstorms with gusty winds. The trough will move across the islands into the southeastern Caribbean tonight through the weekend. NW Caribbean W of 85W .TONIGHT...E winds 10 to 15 kt. Seas 3 to 5 ft. .SAT...E winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A trough extends southwestward from the central Atlantic to near 19N60W. Otherwise, high pressure dominates the basin. The low and trough will shift east-northeastward into the weekend. Elsewhere, high pressure will remain through Sun, with mostly gentle to moderate winds across the area. A cold front will move offshore northeastern Florida Sun night into Mon, reaching from near 31N71W to the NW Bahamas by early Tue, from near 31N70W to near 26N75W by late Tue night, then slowly continue eastward over the remainder of the north-central waters through Wed night while weakening. Scattered showers and thunderstorms are expected with the cold front. Mainly fresh winds southerly winds are expected ahead of the front, with locally strong winds near 31N along with building seas. Moderate to fresh northwest to north winds are expected behind the front, increasing to fresh to strong Mon night. Winds may freshen over the southeastern waters next week as the pressure gradient tightens there leading to building seas. Mainly slight to moderate seas will prevail elsewhere.
