Synopsis for the Gulf of America

918 PM EST Wed Nov 11 2026



.SYNOPSIS...A strong cold front will reach the Texas coast

tomorrow morning, then sweep across the basin through tomorrow

night exiting the area early on Fri. Fresh to locally strong 

N winds are expected in its wake. High pressure will build 

southward into the region this weekend, with increasing easterly 

winds as the high shifts eastward Sun. Strong E 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 E

winds will shift to mostly the NE Gulf Mon and Mon night as the 

front translates eastward across the Gulf.
