Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1018 AM EST Mon Nov 17 2025
SYNOPSIS
Weak high pressure will continue to promote light to
gentle breezes across the Florida Keys coastal waters this
afternoon. Due to the weak flow, there may be a period of
variable breezes this afternoon. Another high pressure system
currently over the Midwest U.S. will continue to drift eastward
through Tuesday while slowly strengthening. This will promote
freshening northeast to east breezes for mid week. This high will
continue moving into the western North Atlantic elongating and
maintaining strength as it does so. This will allow for continued
moderate to fresh breezes through late week.
