Synopsis for the Gulf of America

524 AM EDT Sun Oct 18 2026



.SYNOPSIS...A cold front extends from Marco Island, Florida to 

21N91W where it transitions into a stationary front that extends 

to the central Bay of Campeche. Strong to gale-force winds and 

very rough seas follow the front over the SW Gulf offshore 

Veracruz. Fresh to strong NE winds with frequent gusts to gale 

force winds behind the front over the NE Gulf will continue

through today. The front will slow down as it reaches from the 

Florida Straits to Merida, Mexico later today, then drift to the 

southeast of the Gulf through Tue as it weakens. Gale-force winds 

off Veracruz will persist over the SW Gulf through tonight. 

Fresh to strong NE winds and rough seas will persist elsewhere 

north of the front and E of 90W into Tue. Looking ahead, strong 

high pressure building over the lower Mississippi Valley behind 

the front, will prolong fresh NE to E winds over the eastern half

of the Gulf into mid-week.
