Synopsis for the Gulf of America

359 PM EDT Sat Mar 21 2026



.SYNOPSIS...High pressure over the eastern Gulf will maintain

mostly moderate SE winds and slight to moderate seas across the

western Gulf into the middle of next week. A trough over the Bay

of Campeche in the southwest Gulf will support occasional moderate

to fresh winds off the northern and western coasts of the Yucatan

Peninsula mainly at night through the middle of next week. This 

pattern will also support a light to gentle anticyclonic flow and

slight seas over the eastern Gulf through Wed. Winds may briefly 

increase to fresh speeds over the far NE Gulf late Tue into early

Wed as a frontal boundary clips the area.
