000 FZNT31 KNHC 010311 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1011 PM EST Fri Jan 31 2025 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...Pulsing gale force winds are expected each night and morning offshore of Colombia as a tight pressure gradient persists between ridging in the western Atlantic and low pressure over northwestern Colombia. Very rough seas of 12 to 14 ft are anticipated with these winds. Fresh trades will occur across the southwestern, central and eastern Caribbean through the middle of next week, with winds pulsing to fresh speeds in the northwestern Caribbean by early next week. Pulsing strong winds are expected in the central Caribbean, as well as through the Windward Passage and downwind of Hispaniola. Rough seas will accompany the fresh winds in the southwestern and central Caribbean. Elsewhere, residual E swell will combine with new N swell this weekend, leading to locally rough seas near the Windward and Leeward Islands and through the passages into the Caribbean through next week. Otherwise, slight to moderate seas are expected in the northwestern Caribbean. NW Caribbean W of 85W .TONIGHT...E winds 10 to 15 kt. Seas 4 to 5 ft. .SAT...E winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A tightening pressure gradient between high pressure in the central Atlantic and a cold front moving through the southeastern United States will support widespread fresh E to SE winds north of 22N overnight into Sat morning. Strong S winds will be possible off the coast of Florida, north of 28.5N, overnight. The cold front will push off the southeastern coast of the US overnight and progress eastward before eventually stalling and dissipating this weekend. Winds will diminish in the aforementioned areas by Sat afternoon as the pressure gradient relaxes between the cold front and the ridge. Elsewhere, fresh to strong E winds and rough seas will prevail south of 22N through the middle of next week. North of 22N, gentle to moderate winds and moderate seas are expected for Sun through early next week. ATLC waters from 27N to 31N W of 77W .TONIGHT...S winds 15 to 25 kt.
