Synopsis for the Gulf of America

440 AM EDT Fri Mar 13 2026



.SYNOPSIS...A strong cold front extends from South Florida to the 

Yucatan Peninsula. Fresh to strong N to NE winds and rough seas 

are expected behind the front. The front will stall and significantly

weaken over the southeastern Gulf today, dissipating by tonight. 

Marine conditions will improve significantly through the weekend 

as weak high pressure settles just N of the basin. The next cold 

front is expected to move into the NW Gulf Sun night and reach the

southeastern Gulf by Mon night. Strong to near gale-force N winds

will follow the front along with seas rapidly becoming rough. 

Gale force winds will be possible in the NW Gulf, and offshore 

Tamaulipas and Veracruz, Mexico on Sun night and Mon.
