Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
425 PM EST Sun Dec 7 2025
.SYNOPSIS...Mainly light to gentle southeast to south breezes will
veer to the southwest tonight as a stationary front over mainland
Florida sinks south. Meanwhile, a weather system moves out of the
ArkLaTex region and into the Southeast U.S. The attendent cold
front will sweep through Monday night with a brief period of
moderate to fresh breezes. The potential exists for a more active
weather pattern as the front stalls out across the Straits of
Florida for most of the week.
