Synopsis for the Gulf of America

959 AM EST Thu Nov 12 2026



.SYNOPSIS...A strong cold front in the far NW Gulf will sweep 

across the basin through tonight exiting the area early on Fri. A 

pre-frontal trough in the western Gulf will sustain fresh to 

locally strong northwest to north winds near Tampico and Veracruz 

through Fri afternoon. Elsewhere, moderate to locally fresh N 

winds are expected in the wake of the cold front. High pressure 

will build southward into the region this weekend, with increasing

easterly winds as the high shifts eastward Sun. Fresh to strong 

east winds are likely across portions of the northern Gulf 

starting on Sun as the pressure gradient increases. Looking ahead,

a second cold front should move offshore the Texas coast Mon 

morning. The strong east winds will shift to mostly the NE Gulf 

Mon and Mon night as the front translates eastward across the 

Gulf.
