Synopsis for the Gulf of America 434 PM EDT Fri Apr 4 2025

SYNOPSIS
A strong pressure gradient between the Bermuda High and low pressure over south-central U.S. will continue forcing fresh to near-gale SE winds across the basin through Sat afternoon. The moist SE flow may allow areas of sea fog to persist across the northern Gulf into Sat. A strong late-season cold front will emerge off of the Texas coast Sat night. Fresh to near gale N winds and rapidly building seas will follow the front over the western Gulf Sun and Mon, with northerly gales possible near Tampico on Sun morning, and off Veracruz by late Sun afternoon. The cold front will extend from the Florida panhandle to the eastern Bay of Campeche Mon followed by fresh to strong N winds. The front will weaken as it moves southeast of the area Tue followed by weak high pressure over the northern Gulf. Winds and seas will diminish accordingly through Tue night in all but the far southeast Gulf where fresh winds and rough seas may persist.
