Synopsis for the Gulf of America

318 AM EDT Fri Jun 19 2026



.SYNOPSIS...The western periphery of Atlantic high pressure

extends westward across Florida and to the central Gulf. The

pressure gradient between the high pressure and relatively lower

pressures over Texas and northeastern Mexico will generally

support mostly fresh southerly winds over the western and

central Gulf, and gentle to moderate anticyclonic winds over the

eastern Gulf through Fri. Winds over the western and central

Gulf will change little through early Mon, then diminish to

gentle to moderate speeds afterward. Winds over the eastern Gulf

become light to gentle in speeds beginning Fri night as weak

high pressure settles over the eastern Gulf.
