000 FZNT31 KNHC 030308 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1108 PM EDT Thu May 2 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...High pressure centered N of the region is supporting moderate to fresh trade winds over the central and eastern Caribbean. These winds will gradually subside into the weekend as the pressure gradient relaxes. Moderate to fresh northeast winds are expected in the lee of Cuba, northwestern Caribbean, and just in the Windward Passage into Fri night and in the Windward Passage Sat night and Sun night. Gentle to moderate trade winds are expected over the area through the forecast period, except for mostly fresh winds in the south-central Caribbean. The interaction between a trough along 80W/81W south of 20N with the base of a western Atlantic upper-level trough that extends into the western Caribbean has resulted in the development of scattered showers and thunderstorms from the eastern tip of Cuba to the Windward Passage.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...The gradient between high pressure over the western Atlantic and relatively lower pressure in the Caribbean Sea is allowing for generally moderate to fresh east winds to be south of about 25N, including the approaches to the Windward Passage. A surface trough is expected to soon form north-northeast of Hispaniola. The pressure gradient between the ridge and the trough will support pulsing strong east to southeast east of the trough, and moderate to fresh northeast to east winds west of the trough. Presently, an upper trough is over the western Atlantic. Numerous showers and thunderstorms are east of this trough. The trough is expected to help promote the formation of weak low pressure along the soon to form surface trough on Fri. The low will track east-northeastward Fri through Sat, and weaken back into a trough while exiting the area on Sun. High pressure will then take precedence over the entire area early next week. Moderate to fresh south winds are forecast to develop over the waters east of northeastern Florida Tue and Tue night. ATLC waters from 27N to 31N W of 77W .OVERNIGHT...SE winds 10 kt.
