Synopsis for the Gulf of America

436 PM EDT Wed Aug 19 2026



.SYNOPSIS...Relatively weak high pressure centered over the

central Gulf will prevail over the basin through the forecast 

period. A weak pressure pattern will support mostly gentle to 

moderate winds and slight to locally moderate seas across much of 

the basin. A diurnally induced surface trough will generate fresh to 

locally strong winds north and west of the Yucatan Peninsula in the 

early evenings. These winds will spread westward away from the 

peninsula at night as the trough migrates into the SW Gulf.
