Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1022 PM EST Tue Nov 25 2025
.SYNOPSIS...Ridging extending across the Florida Peninsula will
continue to gradually pull away over the next couple of days. As
this happens, the pressure field across the area will weaken, and
our gentle to moderate easterly breezes will become light to
gentle by Wednesday morning. These conditions won't last long, as
a cold front associated with a deepening trough will push through
the Florida Keys coastal waters late on Thursday. Breezes will
freshen drastically late Thursday as the front approaches, and the
end of the week will see a period of fresh to strong breezes,
along with an increase in shower activity.
