039 FZNT31 KNHC 280850 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 350 AM EST Sat Dec 28 2024 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...Moderate to locally fresh trade winds will prevail across central and eastern portions of the basin through Sun. The strengthening pressure gradient between a building ridge in the western Atlantic, deepening low pressure in the central Atlantic and lower pressure south of the basin will promote locally strong NE winds through the Windward Passage and south of Hispaniola tonight through Sun morning. These winds will diminish early next week as the high pressure north of the area weakens and shifts eastward. Looking ahead, building high pressure north of the area will support increasing winds and seas across the basin by the middle of next week. NW Caribbean W of 85W .TODAY...SE winds 10 to 15 kt.
