Individual waves may be more than twice the significant wave height. Synopsis for the Gulf of Mexico .SYNOPSIS...Moderate to locally fresh return flow is expected to continue through today ahead of the next cold front forecast to enter the NW Gulf this evening. The front will reach from Mobile, AL to Tuxpan, Mexico Sun morning, from Cedar Key, FL to Merida, Mexico in the NW Yucatan peninsula Sun evening, and exit the basin Mon morning. Strong to gale force winds are expected behind the front across the western Gulf, from offshore Texas southward to the Bay of Campeche Sat night through Sun evening. Minimal storm force NW winds are expected offshore of the Veracruz area Sun afternoon. Seas are forecast to build to 16 to 18 ft with the strongest winds. In the eastern and central Gulf, strong to near-gale force winds will follow the front. Scattered thunderstorms are expected to accompany the front as it moves across the Gulf of Mexico. Winds and seas will gradually subside across the basin late Mon. Looking ahead, the aforementioned front may stall across the western Atlantic and NW Caribbean early next week, before moving back northward as a warm front toward the middle of next week. The pressure gradient between very strong high pressure north of the area and lower pressure associated with the warm front may induce fresh to strong E winds and building seas across the northern Gulf by the middle of next week.
