 Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas

 .SYNOPSIS...A series of high pressure systems sliding through the
 North Atlantic will support gentle to moderate northeast to east
 breezes overnight. While the systems slide further eastward in
 the central North Atlantic and the associated ridge weakens,
 breezes will slacken during the upcoming weekend. Periods of
 variable conditions are possible. A potent cold front will push
 through the Florida Keys marine zones on Monday, with fresh to
 strong northerlies expected in its wake for early next week.
