Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1019 AM EDT Sat Mar 28 2026
.SYNOPSIS...The axis of a decaying ridge lies across central
Florida and will slowly slide south through this afternoon. This
will maintain mostly gentle to moderate breezes with the exception
of the extreme Southeast Gulf waters immediately off the
mainland, with light to gentle breezes at times. This axis is
being pushed southward in advance of an approaching frontal
boundary from the north and northeast. Expect this front to sweep
across the Florida Keys coastal waters late today into early
Sunday, with a period of fresh to strong breezes expected in its
wake, lasting through early next week.
