Synopsis for the Gulf of America

503 PM EDT Sat Apr 4 2026



.SYNOPSIS...A cold front will push offshore the Texas coast

tonight and move slowly southeastward across the basin through

Mon night. Ahead of the front, fresh to strong east winds will

continue across the Straits of Florida and over the far southeastern

Gulf through late tonight. Behind the front, strong northeast 

winds and rough seas are expect across portions of the western 

Gulf Sun into Mon, with these conditions spreading into the NE 

Gulf Mon night through early Thu, at which time they will improve 

some. There may be potential for winds in the northeast part of the 

NE Gulf to reach gale-force Wed and Wed night. Scattered showers and 

thunderstorms may precede the front.
