Synopsis for the Gulf of America

1013 PM EDT Fri Mar 20 2026



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

Gulf region and a cold 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 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.
