Synopsis for the Gulf of America

1102 AM EDT Wed Oct 21 2026



.SYNOPSIS...A ridge dominates the Gulf waters supporting gentle 

to moderate winds, with the exception of fresh to strong winds 

over the SW Gulf. The latter winds will persist through tonight. A

tightening pressure gradient between the ridge and a low pressure

forecast to develop near the Bahamas will bring fresh to strong 

NE winds and moderate to rough seas over the eastern Gulf Fri 

night into Sat. These marine conditions will spread westward to 

the central Gulf Sat night through Sun night. Seas are expected to

build to around 12 ft with these winds over the SE Gulf.
