NWS Marine Forecast

   GMZ005-192045-  Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas  433 AM EDT Sat Sep 19 2026      .SYNOPSIS...  Light to gentle breezes will continue through the weekend with  winds mostly out of the east on Saturday and gradually shifting to  the south to southeast into Sunday. In addition, an increasingly  wet weather pattern will develop across the Florida Keys coastal  waters through early next week, as an upper-level low retrogrades  westward across the central Florida Peninsula and eventually  slides into the Gulf later in the weekend. As a result, scattered  to occasional numerous showers and thunderstorms will be a daily  occurence, with gusty winds, lightning strikes, blinding  downpours, and locally hazardous seas being the main hazards  mariners could encounter in the vicinity of this activity. The  upper-level low is forecast to move out of the area early next  week, with winds becoming more southerly and breezes remaining  mainly light to gentle, though occasional periods of moderate  breezes could occur at times. Rain chances will also continue to  remain elevated into next week, as deep moisture lingers across  the Florida Keys coastal waters in the wake of the departing  weather disturbance.    The Approximate Shoreward Edge of the Gulf Stream as of September  15, 2026...    64 NM south-southeast of Dry Tortugas Light, on Loggerhead Key  40 NM south-southeast of Cosgrove Shoal Light, off the Marquesas Keys  36 NM south-southeast of Sand Key Light, off Key West  35 NM southeast of Looe Key, off Big Pine Key  28 NM southeast of Sombrero Key Light, off Marathon  15 NM east-southeast of Alligator Reef Light, off Islamorada  8 NM east-southeast of Molasses Reef Light, off Key Largo  5 NM east-southeast of Carysfort Reef Light, off Ocean Reef    Gulf Stream Information Courtesy of the Naval Oceanographic Office.    $$
