Synopsis for the Gulf of America

1119 PM EDT Tue May 12 2026



.SYNOPSIS...A stationary front extends across central Florida to 

a 1013 mb low near 28N86W from which transitions to a cold front

that extends SW to the eastern Bay of Campeche. The cold front

will stall briefly tonight and exit the SE Gulf by Wed night. 

Winds will be generally moderate or weaker on either side of the 

front, except in the vicinity of the low where fresh to strong

winds are likely as indicated by recent scatterometer data. High 

pressure and quiescent conditions will build behind the front on 

Wed and Thu. Another weak cold front is forecast to enter the NE 

Gulf Thu night and dissipate over the E Gulf on Fri. Otherwise, 

southeast winds are forecast to reach moderate to fresh speeds 

over the western half of the basin this weekend.
