528 FZNT31 KNHC 260311 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 1111 PM EDT Sat May 25 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...Relatively weak high pressure over the western Atlantic will maintain moderate trade winds across the basin, except for pulsing fresh to strong winds in the Gulf of Honduras at night through Tue night. Moderate to fresh trade winds are forecast to develop over the central Caribbean Mon, increasing to fresh to strong speeds late Mon night through late Tue night, then shifting to between 75W and 80W for the rest of the forecast period. A tropical wave presently just west of the Windward Islands will bring scattered to numerous showers and thunderstorms to the E Caribbean waters tonight through Mon. Strong gusty winds and rough seas are likely with this activity. The wave may lose definition as moves across the central Caribbean during mid week. Dense smoke due to agricultural fires in Central America is likely to change over the Gulf of Honduras into the early part of the upcoming week.
