Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
1023 PM EDT Wed Jun 4 2025

.SYNOPSIS...After several days of squally weather, Saharan dust
sliding in from the east will promote much lower rain and thunder
chances over the next several days. High pressure off the Mid-
Alantic coastline will continue to move eastward and merge with a
stronger high centered near the Azores. This will promote a return
to light to gentle east to southeast breezes through Monday.

The Approximate Shoreward Edge of the Gulf Stream as of May 30...

55 NM South of Dry Tortugas Light...on Loggerhead Key.
29 NM South of Cosgrove Shoal Light...off the Marquesas Keys.
20 NM South of Sand Key Light...off Key West.
