Synopsis for the Gulf of America

1014 PM EDT Sun Sep 20 2026



.SYNOPSIS...Weak surface ridging across the southeastern U.S. 

will maintain generally gentle to moderate winds across the basin 

through mid week. A vigorous upper-level low and associated 

surface low or trough over the central Gulf will contribute to 

scattered showers and thunderstorms over the eastern Gulf through 

the midweek, with the Straits of Florida the most active area. 

A cold front may sink into the northern Gulf Thu night through 

Fri, leading to a modest increase in winds across the basin.
