936 FZNT31 KNHC 100241 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1041 PM EDT Fri Aug 9 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...Moderate to locally fresh trades will prevail across the basin through Mon, with the exception of fresh to strong winds near the coast of Colombia tonight, and in the Windward Passage Sat night. A modest tropical wave will bring some showers and thunderstorms for the eastern basin tonight through Sat, and across the central basin over the weekend. Looking ahead, a robust tropical wave currently in the eastern Atlantic will gradually become better organized as it moves westward across the central Atlantic for the next few days. Conditions are forecast to become more conducive for development, and a tropical depression is likely to form Mon or Mon night while approaching the Lesser Antilles. This system is then expected to move west- northwest through the middle of next week and could approach the Greater Antilles. NW Caribbean W of 85W .OVERNIGHT...SE winds 10 to 15 kt.

Synopsis for the the SW N Atlantic including the Bahamas .SYNOPSIS...Atlantic high pressure centered northeast of Bermuda extends southwestward to the central Bahamas, and will shift to the northwest Bahamas and southeast Florida through the weekend, promoting gentle to moderate winds and slight to moderate seas, except for fresh to strong winds during the evening and nighttime hours along the north coast of Hispaniola. Looking ahead, a robust tropical wave currently in the eastern Atlantic will gradually become better organized as it moves westward across the central Atlantic for the next few days. Conditions are forecast to become more conducive for development, and a tropical depression is likely to form Mon or Mon night while approaching the Lesser Antilles. This system is then expected to move west- northwest through the middle of next week and could approach the Greater Antilles. ATLC waters from 27N to 31N W of 77W .OVERNIGHT...S winds 10 to 15 kt.
