000 FZNT31 KNHC 041415 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 915 AM EST Wed Dec 4 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 north of the region will support strong to near-gale NE winds and rough seas over most of the northwest Caribbean and Windward Passage through tonight, and fresh to strong winds pulsing off Colombia farther south from tonight through Sun night. The high pressure will weaken and shift eastward Thu, allowing winds and seas to briefly diminish to mainly fresh speeds. NE swell will lead to seas of 8 to 10 ft for Atlantic waters E of the Leeward Islands into Thu. Looking ahead, high pressure will build again north of the area over the western Atlantic Thu night and prevail through the weekend. This will resume fresh to strong NE to E winds across the NW Caribbean Thu night, and in the Windward Passage and central Caribbean from Sat night through Sun night. Moderate to rough seas expected across these regions through Sun. NW Caribbean W of 85W .TODAY...NE winds 10 to 20 kt. Seas 7 to 10 ft. .TONIGHT...NE winds 10 to 20 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Moderate NW winds and seas follow a leading cold front reaching from 31N55W to NW Hispaniola. A second, reinforcing cold front, reaches from 31N68W across the northern Bahamas to S Florida. Fresht to locally strong N to NW winds and moderate to rough seas are ongoing west of this front to 74W and N of 26N. The fronts will merge and reach from 31N52W to north- central Hispaniola late today, then stall and dissipate west off 55W through Thu. High pressure building in behind the front will continue to support strong NE winds south of 24N, offshore Hispaniola and eastern Cuba through early Thu morning. Looking ahead, the next cold front will move into the waters off northeast Florida late Thu into Fri, bringing large NW swell to the waters between northeast Florida and Bermuda north of 28N through Sun.
