Synopsis for the Gulf of America

452 AM EDT Sun Jun 21 2026



.SYNOPSIS...Relatively weak high pressure will prevail across the

NE Gulf for much of the week. The pressure gradient between the 

high pressure and relatively lower pressures over Texas and 

northeastern Mexico will maintain mostly fresh southerly winds 

over the western and central Gulf through late Mon night before 

diminishing to gentle to moderate speeds. Slight to moderate seas 

will be with these winds. Light winds along with slight seas will 

be over the eastern Gulf through Thu night as a new high center 

becomes situated over the central Gulf.
