Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1027 PM EDT Sun Jul 13 2025
.SYNOPSIS...Shower coverage is forecast to gradually increase
overnight as additional moisture is directed across the CWA. Weak
low pressure tries to develop in the vicinity of Florida heading
through the first half of the week. Initially, the Keys will be on
the southern fringe in a col region resulting in mainly variable
breezes through Monday night. As the weak low pressure area shifts
to the west and high pressure builds in behind, breezes will
freshen becoming southeast to south at first, before becoming east
to southeast for mid to late week. Also, expect increasing
coverage of showers and thunderstorms for the early to middle part
of the week.
