Synopsis for the Gulf of America

935 AM EDT Wed Sep 30 2026



.SYNOPSIS...Showers and thunderstorms will linger in the SE Gulf

through at least this evening. The pressure gradient between high

pressure over the eastern United States and lower pressures in 

Texas and Mexico support moderate to fresh easterly winds over the

western Gulf waters. These winds will expand eastward across the 

basin by tonight as the pressure gradient tightens. The gradient 

will weaken from west to east by the end of the week 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 front.
