Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
430 PM EST Fri Feb 27 2026
.SYNOPSIS...
A ridge across the Atlantic is pulling further east while a
frontal boundary stalls across north central Florida. The
combination of these features will place the Keys in a col region
beginning late tonight through Saturday afternoon. As a result,
expect slackening breezes through this period with variable
directions at times. Despite moisture moving into the region, an
unfavorable wind direction will limit rain chances during the day
Saturday and Sunday but increase chances at night. Thereafter, a
broad high pressure system is forecast to migrate into the eastern
United States, which would support freshening breezes, especially
across the Straits of Florida.
