Synopsis for the Gulf of America

1031 PM EDT Sat Aug 8 2026



.SYNOPSIS...A surface trough extending southwestward from the

Big Bend of Florida into the eastern Gulf will support scattered

showers and thunderstorms through tonight as the trough moves 

inland. Similar activity is expected 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.
