000 FZNT31 KNHC 190858 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 358 AM EST Fri Jan 19 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 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 move into the northwestern Caribbean on Sat, reach from eastern Cuba to the Gulf of Honduras by Sat night and become stationary from near the Windward Passage to near Jamaica and to near northern Belize on Sun. Fresh to strong northeast winds and rough seas are anticipated behind this front. Strong high pressure will build over the western Atlantic early next week, with the resultant tight gradient likely leading to fresh to strong trade winds and building seas across the central and eastern basin through early next week, with gale conditions possible near the coast of Colombia Mon night and Tue night.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A weak cold front extends from near 30N55W to 27N64W, where it becomes a dissipating stationary front to the central Bahamas and to South Florida. A developing cold front that extends from 31N79W to just east of West Palm Beach will sweep across the northern and central waters through late Sat, preceded and followed by fresh to strong winds. Another cold front will move across the waters offshore northern Florida today. This front is forecast to reach the far southern waters by late Sun and become stationary. Strong high pressure building in behind this front will result in increasing winds and building seas north of about 27N into early next week. A tight gradient associated to the high pressure will allow for northeast to east winds to increase to fresh to strong speeds over the waters south of about 27N early next week.
