Individual waves may be more than twice the significant wave height. Synopsis for the Gulf of Mexico .SYNOPSIS...A 1016 mb low pres centered near 28.5N88W will continue moving ESE across the Gulf of Mexico through Wed, with a cold front extending SSW and a warm front extending E from the low. The pressure gradient between the low and strong high pressure over the SE United States is causing frequent gusts to gale-force in the NE Gulf offshore waters and the N-central Gulf coastal waters through the next several hours. NW gale-force winds are also prevailing through the next several hours within 60 nm offshore Veracruz. Fresh to strong N winds are expected elsewhere behind the front through late tonight. Scattered showers and thunderstorms are expected E of the low, as well as in the SE Gulf. Looking ahead, a stronger cold front is expected to move off the Texas coast Thu evening followed by near-gale to gale force NW winds and rough to very rough seas across the basin through Fri night, with strong gales possible off Veracruz beginning of Fri. Conditions will slowly improve through the upcoming weekend. Gulf of Mexico N of 26N W of 87W ...GALE CONDITIONS POSSIBLE THU NIGHT AND FRI... .TONIGHT...N to NE winds 15 to 20 kt.
