Synopsis for the Gulf of America

446 AM EDT Sat Jun 20 2026



.SYNOPSIS...A weak ridge of high pressure extends westward from 

the western Atlantic to 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. These winds are expected to diminish to gentle to moderate 

speeds early next week. Slight to moderate seas will accompany 

these winds. Weak high pressure over the eastern Gulf will 

support light to anticyclonic winds and slight seas there through 

late Mon. A new high center will become established over the 

central Gulf by midweek, with similar conditions expected over

much of the basin at that time.
