Synopsis for the Gulf of America

321 AM EDT Thu Apr 23 2026



.SYNOPSIS...High pressure will prevail 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. The exception will be off the Yucatan 

Peninsula, where a diurnal trough will pulse moderate winds to 

fresh during the evenings.
