NWS Marine Forecast

   GMZ005-071430-  Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas  1017 PM EDT Tue Oct 6 2026      .SYNOPSIS...  Relatively mild marine conditions will continue through the  overnight and early morning hours tomorrow with only isolated  showers and light to gentle southerly breezes. As a cold front  currently draped across northern Florida slowly pushes southward,  rain and thunder chances will increase by Thursday, particularly  across the waters to the west and north of the island chain. A  short break may take place sometime Friday morning or afternoon,  but the weekend will see an additional push of moisture from an  area of unsettled weather currently in the central and eastern  area of Cuba. This could lead to more widely spread showers and  thunderstorms, and their accompanying hazards, through the  weekend.    The Approximate Shoreward Edge of the Gulf Stream as of October 2, 2026...    39 NM south-southeast of Dry Tortugas Light, on Loggerhead Key  14 NM south-southeast of Cosgrove Shoal Light, off the Marquesas Keys  8 NM south-southeast of Sand Key Light, off Key West  2 NM south-southeast of Looe Key, off Big Pine Key  1 NM south-southeast of Sombrero Key Light, off Marathon  0 NM south-southeast of Alligator Reef Light, off Islamorada  2 NM northwest of Molasses Reef Light, off Key Largo  2 NM northwest of Carysfort Reef Light, off Ocean Reef    Gulf Stream Information Courtesy of the Naval Oceanographic Office.    $$
