Synopsis for the Gulf of America

350 PM EDT Wed Apr 22 2026



.SYNOPSIS...Moderate to fresh E to SE winds and moderate seas will

persist in the SE Gulf through Thu night. High pressure will build

across the Gulf region, with a relatively weak pressure gradient 

across the area. This will result in gentle to moderate SE winds 

and moderate seas basin-wide through late week. The exception will

be off the Yucatan Peninsula, where a diurnal trough will allow 

moderate winds to pulse to fresh during the evenings.
