000 FZNT31 KNHC 222030 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 330 PM EST Wed Feb 22 2023 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...A high pressure ridge between the Bahamas and Bermuda will help maintain fresh to strong trades across the central Caribbean for the next several days. Winds will pulse to gale-force off the coast of Colombia each evening/early morning through Sat night. The coverage area of the fresh to strong trades is expected to diminish beginning Sat night, as the high pressure weakens. Fresh to strong NE to E winds will also occur in the Windward Passage and lee of Cuba through Sun night. Strong to near gale E to SE winds in the Gulf of Honduras will continue the next several days. Looking ahead, large long-period N swell may begin impacting the tropical N Atlantic zones starting on Sun night. NW Caribbean W of 85W .TONIGHT...SE winds 15 to 25 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A high pressure ridge between the Bahamas and Bermuda will help maintain fresh to strong trades north of Hispaniola and gentle to moderate winds elsewhere through Sat night. The W end of a weak cold front moving southeastward across the NE forecast waters should reach from 26N55W to 25N65W Thu morning and then dissipate by Fri morning. A stronger cold front will cross our northern border Fri night, extend from 28N55W to 27N65W to 31N78W Sat morning, reach from 23N55W to 24N65W Sun morning, and dissipate Sun night. Strong NW winds are likely on Sat across the NE waters behind the front, with large N swell propagating southward east of 65W though Mon night. Looking ahead, another cold front may arrive over the NE waters on Sun, causing strong breeze conditions on both sides of the front north of 27N through Mon night.
