Individual waves may be more than twice the significant wave height. Synopsis for the Gulf of Mexico .SYNOPSIS...A strong cold front extending from Cape Coral, Florida SW to the Yucatan Peninsula will exit the basin this morning. A strong pressure gradient between the front and high pressure building behind it is supporting fresh to strong northerly winds in the E and SW gulf. Rough seas in the 8 to 15 ft range cover these regions, being the highest seas in the SW gulf. Winds in the SW and E gulf will diminish to moderate to fresh speeds by noon today and seas will subside below 8 ft at night. Looking ahead, the aforementioned front is forecast to stall across the western Atlantic and NW Caribbean on Tue, before drifting back towards the Straits of Florida and the SE Gulf on Wed. The pressure gradient between very strong high pressure north of the area and lower pressure associated with the frontal boundary will lead to fresh to near gale force winds across the E and NW gulf Tue evening through Thu with potential gale force winds developing over the north-central and NE basin Thu night through Fri night.
