759 FZNT31 KNHC 041436 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1036 AM EDT Fri Apr 4 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...A strong pressure gradient from the Bermuda High to the Colombian Low will continue to produce fresh to near gale trades across the Caribbean through Sat afternoon. Winds will reach gale-force off Colombia once again tonight. From Sat night through early next week, the Bermuda High weakens contributing toward reduced winds over the basin. However, strong trades will still continue north of Colombia, south of Hispaniola, and over the Gulf of Honduras on Sun. Rough to very rough seas will accompany the winds. By Mon and Tue as the weakened Bermuda High shifts eastward, trades across the Caribbean will be reduced to moderate to fresh. A cold front may reach the northwest Caribbean Tue with winds shifting from southeasterly to northerly. NW Caribbean W of 85W .THIS AFTERNOON...SE winds 15 to 25 kt.
