Synopsis for the Gulf of America

1025 AM EDT Mon Sep 14 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. Conditions will improve Fri.
