   GMZ005-092115-  Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas  415 AM EST Mon Feb 9 2026      .SYNOPSIS...Mostly gentle to moderate breezes will persist today  as high pressure dominates the weather pattern over our local  waters. The exception will be across the cooler, shallower waters  north of the island chain, where breezes will be light to gentle.  Meanwhile, a broad surface high pressure extends along the  entirety of the Eastern Seaboard and is in the process of becoming  disorganized. A new surface high will consolidate off the  Southeastern U.S. coast Tuesday and slowly meander east out across  the Atlantic. This will maintain a wax and waning of breezes  today through at least Wednesday. Towards the end of the week, the  high will flatten and expand westward across the Florida Keys,  leading to a brief period of light and variable breezes.    The Approximate Shoreward Edge of the Gulf Stream as of February  4...    17 NM South of Dry Tortugas Light...on Loggerhead Key.  15 NM South of Cosgrove Shoal Light...off the Marquesas Keys.  14 NM South of Sand Key Light...off Key West.  17 NM South of Looe Key...off Big Pine Key.  14 NM Southeast of Sombrero Key Light...off Marathon.  9 NM Southeast of Alligator Reef Light...off Islamorada.  4 NM Southeast of Molasses Reef Light...off Key Largo.  5 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.    $$
