 Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
 419 AM EST Sun Dec 7 2025
 
 
 .SYNOPSIS...The Florida Keys will remain in a col region through
 this afternoon. This will promote mainly light to gentle
 southeast breezes, occasionally becoming variable. Thereafter, a
 weather system will move out of the ArkLaTex region and into the
 Southeast U.S. by this evening. The attendent cold front will
 sweep through Monday night with a brief period of moderate to
 fresh breezes. The potential exists for a more active weather
 pattern as the front stalls out across the Straits of Florida for
 most of the week.
