 Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
 435 PM EDT Mon Mar 9 2026
 
 
 .SYNOPSIS...High pressure is centered near Bermuda with the
 western periphery of this ridge extending west into Florida and
 the Gulf. As the high retreats further into the Atlantic this
 week, breezes will shift to the east to southeast. A decaying
 frontal boundary is anticipated to drift southeastward across the
 Gulf late week which may create for a chaotic wind pattern across
 the Florida Keys coastal waters.
