820 FZNT24 KNHC 282020 OFFNT4 Offshore Waters Forecast for the Gulf of America NWS National Hurricane Center Miami, FL 420 PM EDT Fri Mar 28 2025 Offshore Waters Forecast for the Gulf of America 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. GMZ001-290830- Synopsis for the Gulf of America 420 PM EDT Fri Mar 28 2025 .SYNOPSIS...A 1031 mb high is centered between Cape Hatteras and Bermuda this afternoon and extends a ridge westward across the northern Gulf region. The pressure gradient is tight enough to support fresh to strong E to SE winds and moderate to rough seas across most of the basin. Upper level low pressure along the Texas coast is triggering a squall line across the NW Gulf this afternoon between 92W and 95W, and will shift E and weaken tonight. The surface high pressure will drift slowly eastward across the western Atlantic through the weekend, allowing winds to diminish to moderate to fresh speeds by Sat afternoon, with seas then subsiding below 8 ft by late Sat. A cold front is forecast to enter the NW Gulf on Mon, and extend from the Florida Big Bend to NE Mexico by Tue morning before dissipating. $$ GMZ040-290830- NW Gulf of America including Stetson Bank- 420 PM EDT Fri Mar 28 2025 .TONIGHT...SE to S winds 15 to 20 kt.
