Synopsis for the Gulf of America

402 PM EDT Wed Oct 21 2026



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

has a ridge extending into the Gulf region. This system supports  

moderate to locally fresh NE to E winds, with the exception of 

strong to near-gale force NW winds over the SW Gulf. The latter 

winds will persist through tonight. A tightening pressure gradient

between the above mentioned 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 12 or 

13 ft with these winds over the SE Gulf on Sun.
