Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1029 AM EST Tue Feb 10 2026
.SYNOPSIS...High pressure off the Southeast U.S. coastline will
slowly meander east out across the Atlantic. This will maintain
gentle to moderate breezes across much of the Florida Keys coastal
waters through at least Wednesday. Towards the end of the week,
the high will flatten across Florida, leading to slackening
breezes with a couple periods of brief light and variable breezes.
Low pressure developing across the ARK-LA-TEX region and high
pressure off the Southeast U.S. coastline will result in
freshening east to southeast breezes over the weekend.
