Synopsis for the Gulf of America

1033 PM EDT Sun Sep 13 2026



.SYNOPSIS...Weak ridging over the NE Gulf will persist into Tue

supporting relatively tranquil conditions across much of the basin.

The exception will be the Bay of Campeche, where a diurnal trough

will move westward offshore the Yucatan Peninsula each evening

through late this week, bringing nightly pulses of fresh NE 

winds. Starting late Tue, stronger high pressure building 

southward from the eastern United States will lead to increasing 

NE to E winds over the basin, with speeds reaching fresh to strong

and rough seas over the northern Gulf Wed through Thu night.
