Synopsis for the Gulf of America

930 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.
