Synopsis for the Gulf of America

1112 AM EDT Fri Mar 20 2026



.SYNOPSIS...The pressure gradient between a ridge across the

Gulf region and a weakening stationary front over the central  

Caribbean Sea will continue to support fresh to locally strong NE 

winds and moderate to rough seas over the SE Gulf, including the 

Straits of Florida, through late today. Moderate to fresh NE winds

are expected nightly, through the forecast period, across the 

eastern Bay of Campeche due to local effects associated with a 

thermal trough. Elsewhere, moderate or weaker winds, and slight to

moderate seas will prevail through Tue night.
