Synopsis for the Gulf of America

346 PM EDT Sat Oct 17 2026



.SYNOPSIS...A cold front extends from Sarasota, Florida to the 

central Bay of Campeche. Strong gale force winds and very rough 

seas follow the front over the west-central Gulf, with minimal 

storm force in the SW Gulf near Veracruz. Fresh to strong NE winds

with frequent gusts to gale force follow the front elsewhere 

behind the front including over the northern Gulf. The front will

slow down as it reaches from the Florida Straits to Merida, 

Mexico by early Sun, then drift to the southeast of the Gulf 

through Tue as it weakens. Storm force winds off Veracruz will 

diminish to strong gale this evening, then persist over the SW 

Gulf through Sun night. Gales will diminish in the west-central

Gulf by early Sun, and frequent gusts to gale force elsewhere 

behind the front should diminish by this evening. Strong NE winds 

and rough seas will persist elsewhere north of the front into

early next week. Looking ahead, strong high pressure will build 

over the lower Mississippi Valley behind the front, promoting 

fresh NE to E winds mainly over the eastern half of the Gulf into 

mid-week.
