Synopsis for the Gulf of America 408 PM EDT Mon Sep 28 2026

SYNOPSIS
A weak stationary front over the north-central 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 northwest Gulf Fri and Sat.
