000 FZNT31 KNHC 110241 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 941 PM EST Fri Jan 10 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 cold front will move into the far northeast Caribbean overnight, then stall and dissipate through late Sat night. High pressure will build in the wake of the front across the western Atlantic into Sat. Large, long- period northerly swell will also accompany the front, impacting the Atlantic passages into the northeast Caribbean Sat, the Atlantic waters east off the Leeward Islands starting Sat night, and the waters east of the Windward Islands by early Sun before subsiding into Mon. The pattern will also support moderate to fresh trade winds over the eastern and south- central Caribbean, with stronger winds pulsing off Colombia through early next week.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front is moving south of 22N west of 55W this afternoon. Strong to gale force are both ahead and behind the front north of 22N, between 55W and 70W, along with large, long- period northerly swell. The winds will diminish overnight into Sat as the front moves southeast of the area and weakens. Farther west, expect SW gales and rough seas off northwest Florida late tonight into early Sat, ahead of another cold front that will move off the coast Sat. This front will shift across the forecast waters and exit east of the area through Mon. As with the earlier front, gale force winds and rough seas are possible over the northern waters in the vicinity of the front through Sun. These winds and seas will diminish as high pressure builds over the basin Sun into Mon. Looking ahead, another front will move into the waters off northeast Florida Tue.
