GMZ001-210830- Synopsis for the Gulf of America 423 PM EDT Thu Mar 20 2025 .SYNOPSIS...Widespread strong to near-gale force winds, with gusts to gale force, and rough to very rough seas will occur today in the wake of a cold front extending from the Florida Big Bend to 19N96W in the western Bay of Campeche. Gale force winds and very rough seas will continue this afternoon offshore of Veracruz. The front will exit the basin late tonight, and winds and seas are expected to diminish from northwest to southeast on Fri. High pressure will build over the basin Fri, supporting moderate to locally fresh S to SE winds over the western and central Gulf, and gentle to moderate winds in the eastern basin through this weekend. A surface trough over the Yucatan Peninsula will move into the Bay of Campeche nightly Fri through Sun, enhancing winds to fresh to strong speeds in the Peninsula adjacent waters. Looking ahead, the next cold front is slated to enter the northwestern basin early next week. $$ GMZ040-210830- NW Gulf of America including Stetson Bank- 423 PM EDT Thu Mar 20 2025 .TONIGHT...NE winds 10 to 15 kt.
