Synopsis for the Gulf of America

556 AM EDT Sat Oct 31 2026



.SYNOPSIS...A modest pressure gradient between high pressure

over the southeastern U.S. building southward and relatively lower 

pressure to its south is providing for moderate to fresh northeast 

to east winds and moderate seas across the northeast and north-

central Gulf. These winds will increase to fresh to strong speeds 

late tonight and continue into Mon before diminishing to mostly 

fresh speeds. Looking ahead, a cold front is expected to enter the 

NW Gulf Tue night, and move slowly southeastward reaching the east-

central Gulf by Wed night, followed by mostly fresh northwest to 

north winds.
