Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
448 AM EST Wed Nov 26 2025

.SYNOPSIS...The tail end of a surface ridge will pull away today,
and a weak pressure field left in its place will result in light
to gentle breezes today. 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 Thanksgiving. Breezes will
freshen drastically late Thursday night 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.
