Synopsis for the Gulf of America

318 PM EST Fri Nov 21 2025



.SYNOPSIS...Moderate to occasionally fresh E to NE winds are 

expected each afternoon and evening in the Bay of Campeche and 

north of the Yucatan Peninsula as a diurnal trough develops and 

moves westward over the region. Moderate or weaker winds and 

slight to moderate seas are expected elsewhere through much of 

this weekend. Looking ahead, fresh to locally strong SE winds are 

expected to develop offshore of Texas and eastern Mexico late this

weekend into next week, with locally fresh SE to SW winds 

expanding over the central and eastern Gulf by midweek, as a cold 

front moves over the southern U.S.
