Synopsis for the Gulf of America

1017 AM EST Wed Nov 11 2026



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

on Thu, then sweep across the Gulf through Thu night exiting 

the area early on Fri. Fresh to locally strong north winds 

and building seas 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 east winds 

are likely across portions of the northern Gulf starting Sun as 

the pressure gradient increases ahead of a low pressure and 

attendant cold front that will approach the NW Gulf for the start 

of next week.
