Individual waves may be more than twice the significant wave height. GMZ001-190830- Synopsis for the Gulf of Mexico 420 PM EDT Sat Mar 18 2023 .SYNOPSIS...Strong winds and rough seas follow a cold front extending from the Florida Big Bend area near Crystal River to near Coatzacoalcos, Mexico. Scattered thunderstorms are evident ahead of the front over the southeastern Gulf. Wind will reach gale force off Veracruz, Mexico overnight as the front extends from southwest Florida to the northwest Yucatan Peninsula by early Sun. Frequent gusts to gale force are possible behind the front late Sun over the central Gulf. The front will move southeast of the area by early Mon. High pressure building in the wake of the front will allow winds and seas to diminish across most the Gulf through Mon, although fresh to strong winds over the western Gulf will persist and shift SE Mon night into Tue. Looking ahead, winds and seas will continue to diminish across the remainder of the basin through mid week. $$ GMZ040-190830- NW Gulf including Stetson Bank- 420 PM EDT Sat Mar 18 2023 .TONIGHT...N to NE winds 20 to 25 kt.
