Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
434 AM EST Fri Nov 14 2025

.SYNOPSIS...Moderate breezes will gradually slacken to light to
gentle over the weekend, while high pressure across the Southeast
U.S. will gradually move 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 slacken further
becoming light and variable Sunday and Sunday night. High pressure
will then lift northward and gradually strengthen, allowing for a
slow freshening of breezes.
