000 FZNT31 KNHC 181448 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 948 AM EST Thu Jan 18 2024 Marine Weather HF Voice Broadcast for the Tropical N Atlantic from 07N to 22N between 55W and 64W, the SW N Atlantic S of 31N W of 65W including 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 between 55W and 64W .SYNOPSIS...High pressure northeast of the area combined with the Colombian low will continue to support fresh to strong trade winds and rough seas across the eastern and central Caribbean through Fri night. Winds off northwestern Colombia will pulse to gale-force tonight. The high pressure will also cause fresh to strong trades with moderate to rough seas just east of the Lesser Antilles through Sat. A cold front is forecast to reach the northwestern Caribbean on Sat, reaching from eastern Cuba to the Gulf of Honduras by Sat night and then stalling from near the Windward Passage to southwest of Jamaica on Sun. Fresh to strong NE winds and rough seas are anticipated behind this front. Strong high pressure east of this front is expected to bring fresh to strong winds and building seas across the central and eastern basin through early next week with gale conditions possible near the coast of Colombia.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A cold front extends southwestward from east of Bermuda across 31N58W to 25N74W, then continues as a stationary front to western Cuba. By this evening, the entire portion will become stationary and then begin to lift northward as a warm front ahead of the next cold front forecast to enter the northeast Florida offshore waters on Fri. This second front will cause winds and seas to build once again north of 27N into early next week. High pressure building east of the front is going to keep fresh winds and moderate to rough seas near the southeast Bahamas, Greater Antilles and Leeward Islands through Fri.
