Synopsis for the Gulf of America

1126 PM EDT Sat Oct 17 2026



.SYNOPSIS...A cold front extends from Naples, Florida to 21N93W

where it transitions to 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 west-central Gulf, with the

strongest winds being in the SW Gulf offshore Veracruz. Fresh to 

strong NE winds with frequent gusts to gale force winds are behind

the front over the NE 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.

Gale-force winds off Veracruz will 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 Sun early in the afternoon. 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.
