000 FZNT31 KNHC 140920 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 420 AM EST Sat Dec 14 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...Strong ridging over the SE United States will continue to force fresh to strong NE winds across the central and W Caribbean including through the Windward Passage until early Sun. A broad surface trough over the SW N Atlantic waters extending into the NE Caribbean will gradually move westward to the SW Caribbean through Mon. This trough will cause the pressure gradient to relax across most of the Caribbean, allowing for gentle to moderate trades across the basin through Tue. Looking ahead, a building ridge may enhance the trades over the central Caribbean to fresh to strong speeds Tue night through Wed night. NW Caribbean W of 85W .TODAY...NE winds 10 to 20 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A weakening stationary front that extends from just east of Bermuda to the central Bahamas offshore waters should dissipate later this morning. A tight pressure gradient between a strong ridge building in the wake of the front and a westward moving trough, currently N of Puerto Rico, is supporting strong to gale-force NE winds and very rough seas over all of the waters west of 65W. Gale force winds between the waters of the Bahamas and Bermuda will prevail through Sun. Conditions will gradually improve late Sun and Mon, and by Tue and Wed winds will be reduced to moderate to fresh across the entire area.
