Synopsis for the Gulf of America

1055 AM EDT Sun Aug 9 2026



.SYNOPSIS...A surface trough extends from near Panama City,

Florida to 29N89W and to near 28N93W. Isolated showers and 

thunderstorms are near the trough. The trough will move inland 

the northern Gulf coast this evening. Otherwise, a surface ridge 

extends from the Bermuda High westward across the northern Gulf, 

and will dominate most of the basin through late Tue. This will 

support gentle to moderate E to SE winds north of 24N with slight 

seas. Pulses of fresh winds will occur north and west of the 

Yucatan Peninsula and into the Bay of Campeche each evening and 

night as a diurnal surface trough migrates from the Yucatan 

Peninsula westward across the SW Gulf.
