Northerly winds ramp up in the wake of the front, approaching gale criteria for the western marine zones overnight Saturday into Sunday. As a result, a gale watch has been issued for all Gulf waters west of Intracoastal City for Sunday morning, with a small craft advisory for the remaining Gulf waters and all lakes/bays for this time frame. Small craft advisories will likely need to be extended through Sunday and perhaps into Monday as elevated flow turns to the northeast. Winds will turn easterly to southeasterly starting Monday night and diminish to around 10-15 kt, which will likely continue for much of the rest of the week.
