000 FZNT31 KNHC 140309 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1009 PM EST Thu Feb 13 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...Widespread fresh E trade winds and rough seas will occur across the southwestern, central and eastern Caribbean through this weekend as a strong pressure gradient prevails between low pressure over northwestern Colombia and high pressure in the western Atlantic. Winds will pulse to gale force tonight into early Fri offshore of NW Colombia, with winds reaching near- gale force each night and early morning thereafter into Sun. Very rough seas will occur near and to the west of the highest winds. Pulsing strong winds are expected across the central Caribbean through this weekend, as well as in the Gulf of Venezuela, through the Atlantic Passages, in the lee of Cuba and Hispaniola, and in the Gulf of Honduras. Otherwise, moderate to fresh winds will occur in the northwestern Caribbean through this weekend. 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...Fresh to strong E trade winds are expected south of 25N, including through the Atlantic Passages into the Caribbean through Fri night, with fresh to pulsing strong E winds expected into early next week. A long-period E swell will support rough seas in this region, with locally very rough seas possible east of the Windward Islands through Sat. A strong cold front is expected to push off the coast of the southeastern United States Fri morning, leading to fresh to strong NE to E winds behind the front, generally north of 28.5N and west of 60W, on Fri. Rough seas will occur in tandem with these winds. The cold front will stall along 28N on Sat, and moderate to fresh NE to E winds will prevail north of this boundary. Looking ahead, fresh to strong S to SW winds and rough seas will develop west of 70W off the coast of Florida on Sun ahead of a very strong storm system moving through the eastern United States. A cold front associated with this system will exit the SE United States late Sun and reach from Bermuda to the Florida Straits by Mon afternoon, then drift SE and weaken considerably through Tue.
