642 FZNT31 KNHC 150314 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1014 PM EST Fri Feb 14 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...Winds will pulse to gale force offshore of Colombia tonight into early Sat, and again Sat night into early Sun as a strong pressure gradient prevails between high pressure in the western Atlantic and the Colombian low. Locally very rough seas are expected near and to the west of the gale force winds. Widespread fresh trade winds and rough seas will occur across the central and eastern Caribbean through this weekend, with winds pulsing to strong speeds in the Gulf of Venezuela, through the Windward Passage, downwind of Hispaniola, in the lee of Cuba, in the Gulf of Honduras, and through the Atlantic Passages. Elsewhere, pulsing fresh NE winds are expected in the western basin. Looking ahead, a decreasing pressure gradient between the Colombian low and high pressure in the western and central Atlantic will support moderate to fresh trade winds and locally rough seas across the basin into early next week, with locally strong winds occurring offshore of Colombia.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extending from 31N62W to south Florida will progress southeastward overnight before stalling along 28N on Sat, and dissipate by Sun. Fresh to strong NE to E winds are expected north of the front overnight through Sat morning. Pulsing fresh to locally strong NE to E winds will also occur north of Hispaniola and Cuba and near the Bahamas through Sat. A long-period N swell associated with this cold front will produce rough seas north of 27N through Sat morning, and north of 23N by Sun morning. Very rough seas of 12 to 14 ft will be possible north of 28N and east of 60W late Sat through Sun. Farther south, fresh trade winds and rough seas will prevail south of 23N through this weekend, with winds pulsing to strong speeds at times east of the Windward Islands. Moderate to locally fresh trade winds and rough seas will then occur in this region through at least the middle of next week. Elsewhere, winds will turn to the S and strengthen west of 70W off the coast of Florida on Sun ahead of the next cold front forecast to move off the coast of the southeastern United States early on Mon. This front will reach from Bermuda to the Florida Straits by Mon afternoon, then drift SE and weaken considerably through Tue. ATLC waters from 27N to 31N W of 77W .TONIGHT...E winds 15 to 25 kt.
