Individual waves may be more than twice the significant wave height. Synopsis for the Gulf of Mexico .SYNOPSIS...A stationary front extending from north of Tampa Bay, FL to the north-central Gulf near 28N90W to Veracruz, Mexico is beginning to lift N this morning. A second push of cold air and a developing low pressure over the NE Gulf along the frontal boundary will allow the transition to a cold front this evening. The low will move NE across Florida toward the western Atlantic Ocean early Tue morning, thus dragging the cold front across the SE Gulf and South Florida by Wed. The front will dissipate across the Straits of Florida Thu and return flow will establish basin-wide on Fri.
