Individual waves may be more than twice the significant wave height. Synopsis for the Gulf of Mexico .SYNOPSIS...Weak high pressure off the SE United States combined with surface troughing over Mexico will continue to force moderate to fresh SE to S return flow over the Gulf of Mexico through Fri. The diurnal trough forming over the Yucatan will promote strong E winds over the SW Gulf tonight and Thu night. Agricultural and seasonal fires over Mexico and Central America result in smoke and haze over the the SW Gulf and the Bay Campeche. Mariners may experience reduced visibility in these waters. Winds will diminish across the Gulf Fri ahead of a cold front that is expected to enter the NW Gulf Fri night. N to NE winds behind the front should be moderate to fresh on Sat. By Sun morning, the dissipating front will extend from SW Florida to near the Texas- Mexico border. Looking ahead, as a surface ridge builds to the north of the Gulf, fresh to strong E to SE to E winds are expected on Sun and Mon over most of the Gulf.
