Synopsis for the Gulf of America

248 PM EST Mon Nov 9 2026



.SYNOPSIS...Broad high pressure across the area supports gentle 

to moderate winds except locally fresh in the NW Gulf. Slight seas

dominate the NE half of the basin with moderate seas elsewhere. 

Winds will diminish to light to gentle across the basin by 

midweek. The next cold front will move into the NW Gulf on Thu and

rapidly shift across the Gulf basin, moving SE of the area Fri. 

The front will be followed by fresh to locally strong winds and 

building seas. High pressure will settle across the basin in the

wake of the front during the weekend with moderate to fresh return

flow.
