Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
426 PM 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. 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.
