Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1036 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.
The Approximate Shoreward Edge of the Gulf Stream as of March 7...
55 NM South of Dry Tortugas Light...on Loggerhead Key.
15 NM South of Cosgrove Shoal Light...off the Marquesas Keys.
7 NM South of Sand Key Light...off Key West.
8 NM South of Looe Key...off Big Pine Key.
