Synopsis for the Gulf of America

430 AM EDT Fri Jun 12 2026



.SYNOPSIS...1019 mb high pressure near 29N69W extends a ridge

westward across Florida and the NE Gulf of America, and will

generally remain in place through early next week. A surface trough

from the eastern Bay of Campeche northeastward to offshore of the  

Yucatan Peninsula extends to the middle atmosphere, and will 

shift slowly northwestward through the weekend, and move inland 

across NE Mexico and S Texas on Sun. This pattern will support 

fresh to strong SE winds and moderate to rough seas shifting from 

the northwestern Yucatan Peninsula to the coast of Texas through 

early Sun, accompanied by numerous showers and thunderstorms. 

Winds and seas will diminish Mon and Tue after the low pressure 

moves inland and weakens.
