   GMZ005-060830-  Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas  424 PM EDT Tue May 5 2026      .SYNOPSIS...A poorly defined wind field with light and variable  breezes will persist until ridging can become better established  across the Florida peninsula on Wednesday. At that point, winds  will become a climatologically appropriate light to gentle east to  southeasterly breeze. Deep layered ridging will dominate from mid  week through the remainder of the work week. This along with very  weak forcing will keep rain chances out until at least Saturday  when southeasterly breezes strengthen to gentle to moderate,  bringing in increased boundary layer moisture and opening the door  to maritime showers.    The Approximate Shoreward Edge of the Gulf Stream as of May 05...    23 NM South of Dry Tortugas Light...on Loggerhead Key.  13 NM South of Cosgrove Shoal Light...off the Marquesas Keys.  12 NM South of Sand Key Light...off Key West.  14 NM South of Looe Key...off Big Pine Key.  14 NM Southeast of Sombrero Key Light...off Marathon.  10 NM Southeast of Alligator Reef Light...off Islamorada.  8 NM Southeast of Molasses Reef Light...off Key Largo.  7 NM Southeast of Carysfort Reef Light...off Ocean Reef.    Gulf Stream Information Courtesy of the National Weather Service in  Key West based on products from NASA SPoRT and RTOFS.    $$
