Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1017 AM EDT Tue Apr 14 2026
.SYNOPSIS...A high pressure system over the central North Atlantic
will maintain fresh northeast to east breezes. Occasional fast-
moving light showers cannot be ruled out, especially in the
overnight periods. Breezes may briefly lull during the late
afternoon and early evening across the Gulf waters due to the
heating of South Florida. As the high moves farther eastward and
slowly weakens, easterly breezes will modestly slacken for
Thursday and Friday.
