Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1022 AM EST Sun Nov 16 2025

.SYNOPSIS...Weak high pressure will continue to promote light to
gentle breezes across the Florida Keys coastal waters through
Monday. Due to the weak flow, there may be periods of light and
variable breezes, mainly in the afternoons. Another high pressure
system will traverse across the eastern United States early this
week while slowly strengthening. This will allow for freshening
northeast to east breezes for the middle and latter part of the
week.
