320 PM EDT Fri Aug 21 2026
.SYNOPSIS...Relatively weak high pressure centered over the
central Gulf will prevail into the middle of next week, supporting
gentle to moderate winds and slight to locally moderate seas. A
surface trough will generate fresh winds north and west of the
Yucatan Peninsula in the early evenings. These winds will spread
westward away from the peninsula at night as the trough migrates
into the SW Gulf.
