 Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
 416 PM EST Thu Nov 13 2025
 
 
 .SYNOPSIS...Breezes will continue to peak overnight and lull
 during the morning and afternoon through Saturday. Thereafter,
 high pressure across the Southeast U.S. will gradually sink across
 or just north of the Florida Keys. This feature will also weaken
 such that the coastal waters surrounding the Keys, or at least
 portions, will become light and variable Sunday and Sunday night.
 High pressure will then lift northward and gradually strengthen,
 allowing for a slow freshening of breezes.
