Synopsis for the Gulf of America

406 PM EDT Wed Aug 20 2025



.SYNOPSIS...Moderate to locally fresh NE to SE winds will be 

possible over the south-central Gulf each afternoon and evening 

through this weekend as a trough develops over the Yucatan 

Peninsula and moves westward. Otherwise, gentle to locally 

moderate winds and slight seas will prevail over the remainder of

the basin as weak high pressure dominates the region.
