Synopsis for the Gulf of America

422 AM EDT Sun Aug 9 2026



.SYNOPSIS...A surface trough extends across the NE Gulf supporting 

scattered showers and thunderstorms through today as the trough 

moves inland. Similar activity is noted in the Bay of Campeche 

and SW Gulf with the passage of a diurnal surface trough. 

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.
