535 FZNT31 KNHC 290249 OFFN20 Marine Weather HF Voice Broadcast NWS National Hurricane Center Miami, FL 949 PM EST Fri Nov 28 2025 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...The pressure gradient between high pressure over the central Atlantic and lower pressure over the SW Caribbean will sustain fresh to locally strong trades over the SW and south- central Caribbean overnight, with moderate trades elsewhere in the central and eastern basin prevailing through the weekend as the gradient weakens some. A stationary front extending from central Cuba to Belize will dissipate through late Sat. Fresh to strong N winds and rough seas behind it through the Yucatan Channel will diminish as the front decays. A very weak pressure gradient across the region Mon and Tue will lead to tranquil marine conditions. NW Caribbean W of 85W .TONIGHT...NE winds 15 to 25 kt, diminishing to 10 to 15 kt after midnight.
