Synopsis for the Gulf of America

1050 PM EDT Wed Sep 30 2026



.SYNOPSIS...Scattered showers and isolated thunderstorms will 

linger in the eastern Gulf tonight and spread over much of the 

basin over the next few days. The pressure gradient between high 

pressure over the eastern United States and lower pressures in 

Texas and Mexico support increasing winds to moderate to fresh 

speeds across the basin tonight. The gradient will weaken from 

west to east by Fri into the weekend as a frontal boundary 

approaches the western Gulf waters, possibly moving into the basin

by the end of the weekend with weakening winds and subsiding seas

ahead of it. Increasing winds and building seas are possible 

behind the very slow moving or stalling front.
