Synopsis for the Gulf of America

1034 PM EDT Sat Sep 13 2025



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

Texas, with ridging extending into the NW Gulf is presently 

allowing for gentle to moderate northeast to east winds along

with mostly slight seas across most of the basin. The high 

pressure will be replaced by another area of high pressure that 

will build southward into the northern Gulf next week leading to 

moderate to fresh winds and building seas over the NW Gulf, and 

off the west coast of the Yucatan Peninsula. Otherwise, little 

change is expected through the period.
