Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1027 PM EDT Thu Apr 25 2024

.SYNOPSIS...Gentle to moderate breezes will prevail in the near
term as an Atlantic ridge extends westward across Florida. This
high will be subsumed by a larger high spreading into the western
North Atlantic over the next couple of days. This will be
accompanied by sharply freshening easterly breezes. Breezes will
diminish somewhat Monday through Tuesday as the high loses
latitude towards the Bahamas.

The Approximate Shoreward Edge of the Gulf Stream is currently
unavailable.
