869 FZNT31 KNHC 121536 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1036 AM EST Wed Feb 12 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...The pressure gradient between a high pressure ridge across the western Atlantic along 29N and low pressure over northwestern Colombia will support strong trade winds across the central Caribbean pulsing to gale force each night and early morning near the coast of NW Colombia through Thu night. Rough to very rough seas are expected near and to the west of the highest winds. Fresh E to NE trade winds and rough seas are expected across the remainder of southwestern and central Caribbean into the weekend, with winds pulsing to strong speeds through the Windward Passage, in the Gulf of Venezuela, and S of Hispaniola. Atlantic high pressure will move to near 55W early Thu through Fri, briefly shifting the zone of strong trade winds and rough seas across the eastern Caribbean and Tropical North Atlantic waters. Looking ahead, Atlantic high pressure will begin to shift eastward Mon and Tue, leading to decreasing winds and seas across the basin. NW Caribbean W of 85W .TODAY...SE winds 10 to 20 kt.
