Individual waves may be more than twice the significant wave height. Synopsis for the Gulf of Mexico .SYNOPSIS...A cold front extends from South Florida to 27N91W where it becomes a warm front to a weak 1015 mb low over the NW Gulf near 26N95W. A stationary front then trails from the low to to 20N97W. A tight gradient between the fronts and strong high pressure building over the SE CONUS is allowing for strong NE winds over the northern half of the basin W of 89W, and fresh N to NE winds E of 89W. The cold front will continue to move quickly across the Gulf E of 96W through tonight and become stationary over the SE Gulf on Mon. The low will slowly move northeastward through Mon night, then east northeastward across the N central waters through Thu night and the NE Gulf by Fri, dragging a new cold front across the SW Gulf. The tight gradient will gradually slackens allowing for the fresh to strong winds to slightly diminish Mon through early Tue. These winds are expected to increase again late Tue or Wed as another low pressure forms over the NW Gulf and tracks northeastward toward northern Florida.
