A cold front extends from the 1012 mb low near 26N87W, to 18.5N92.5W. The low will track E-NE slowly, to the far eastern Gulf waters through early Friday, before moving inland in central Florida Friday afternoon, pushing the cold front to the far SE waters by Saturday. A tight pressure gradient behind the front has been bringing gale-force conditions to much of the western waters today. Gale-force conditions to continue in the far SW waters into early Thursday. High pressure will build across the area in the wake of the front through Sunday, allowing for winds and seas to decrease. Gulf of Mexico N of 26N W of 87W .TONIGHT...N winds 15 to 25 kt.
