A strong cold front is forecast to enter the northwestern Gulf later this morning, causing strong to near-gale northerly winds and building seas. As this front moves southeastward, these conditions will spread to the north-central and southwestern Gulf by this afternoon. Winds will reach near-gale to gale force at the west-central Gulf and western Bay of Campeche near Veracruz, Mexico late this afternoon through tonight. This front will reach from southern Florida to the eastern Bay of Campeche on Sat evening, spreading strong to near-gale N to NE winds and rough seas into the east-central and central Gulf. Frequent gusts to gale-force are possible at the central Gulf late Sat afternoon through Sun, and at the eastern Bay of Campeche Sun night. As the front continues southeastward passing through the Yucatan Channel and Florida Straits on Sun night, both winds and seas should gradually subside across the Gulf on Mon.
