Synopsis for the Gulf of Mexico

cold front is forecast to enter the NW Gulf Sat evening. The
front will reach from Cedar Key, Florida to Cancun, Mexico Sun
evening, and exit the basin by Mon morning. Strong to gale force
winds are expected behind the front, with gale force winds
possible across the western Gulf, from offshore southern Texas
southward to the Bay of Campeche Sat night through Sun evening.
Strong NW gales to near storm-force winds are possible offshore
