Synopsis for the Gulf of America

350 PM EDT Fri Mar 20 2026



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

Gulf region and a 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 tonight. 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. Winds may briefly increase to fresh 

speeds over the NE Gulf late Tue into early Wed as the pressure 

gradient tightens there.
