Synopsis for the Gulf of America

404 AM EDT Thu Oct 22 2026



.SYNOPSIS...High pressure over the eastern of the United States

supports moderate to locally fresh NE to E winds across the

Gulf. A tightening pressure gradient between the high pressure

and a low pressure forecast to develop near the Bahamas will

bring fresh to strong NE winds and rough to very rough seas over 

the eastern Gulf Fri night into Sat. These marine conditions will 

spread westward to the central Gulf Sat night through early next 

week.
