Individual waves may be more than twice the significant wave height. Synopsis for the Gulf of Mexico .SYNOPSIS...A cold front extends from Ft. Myers, FL to 25N85W, where it becomes a stationary front to the SW Bay of Campeche near 20N96W. The cold front will become stationary early this evening from the Straits of Florida to 20N95W. The front will then move northward across the basin as a warm front tonight through early Mon, accompanied by scattered showers and thunderstorms, as southeasterly winds increase to strong to near gale force across much of the basin. A very strong cold front will enter the western Gulf of Mexico early Mon evening, reach from Pensacola, FL to Veracruz, Mexico early Tue, from near Ft. Myers, FL to Cancun, Mexico Tue evening, and move southeast of the basin late Tue night. Gale force winds are expected to begin by late Mon morning over the north-central Gulf, with gusts reaching strong gale force speeds. Near-gale force winds are expected for most of the Gulf of Mexico on both sides of the front, Mon through Tue, with several areas experiencing sustained gale force winds. A squall line containing severe thunderstorms is likely to occur over the northern Gulf of Mexico just prior to the frontal passage. Conditions quiet down Wed through Thu as high pressure shifts E across the central Gulf in the wake of the front.
