Synopsis for the Gulf of America

1124 PM EDT Mon Sep 28 2026



.SYNOPSIS...A weak stationary front over the NE Gulf will 

dissipate through early Tue. High pressure north of the front is 

supporting gentle to moderate E to SE winds across the Gulf. 

Expect moderate to fresh winds and building seas over mostly the 

western Gulf by Tue night, as the high pressure shifts eastward 

ahead of a cold front moving through the Southern Plains. Looking 

ahead, winds and seas will diminish late in the week as the front 

approaches the NW Gulf Fri and Sat.
