000 FZNT31 KNHC 250309 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1109 PM EDT Wed Apr 24 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...High pressure north of the Greater Antilles is sustaining moderate to fresh trade winds, except for fresh to strong winds in the Windward Passage and in the south- central Caribbean. The gradient associated to the high pressure will maintain fresh to strong winds just north of Colombia, through the Windward Passage, and in the lee of Cuba through Thu night. Looking ahead, strengthening of the high pressure starting late Fri will also force fresh to strong trade winds in the Gulf of Honduras, lee of Cuba, Windward Passage and just south of Hispaniola through early next week.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...A weakening cold front extends from 31N57W to 25N67W and to near 22N76W. The front will stall and gradually weaken to a dissipating trough early Thu. Northwest to north swell near the front will subside late tonight. Fairly tranquil conditions are forecast Thu and Thu night. Looking ahead, a new cold front is forecast to merge with the trough and progress eastward, reaching from near 31N57W to eastern Cuba early Sat morning, from near 25N55W to Hispaniola early Sun, then stall and weaken into a trough over the far southeastern part late Sun through Mon night. North swell behind this next front will build seas over most of the area northeast of the Bahamas by Sun. Strengthening high pressure in the wake of the front will result in fresh to strong north to northeast winds behind the front from late Fri through Sun. By late Sun, these winds are expected to be at mainly fresh speeds south of 29N and west f 60W. At that time, fresh to strong west to northwest winds are expected over the far northeast forecast along with building sea. ATLC waters from 27N to 31N W of 77W .OVERNIGHT...S winds less than 10 kt.
