NWS Marine Forecast

   GMZ005-080245-  Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas  1044 AM EDT Wed Oct 7 2026      .SYNOPSIS...Tropical Storm Isaias, currently over the southwestern  Gulf waters, is expected to move towards the North Gulf Coast  over the next few days, strengthening as it does so. A cold front  currently draped across north-central Florida will slowly press  southward infringing on the surface ridge to its south. In doing  so, these systems will act in tandem and create a tightening  pressure gradient across the Keys, resulting in freshening mainly  southeast breezes as we head into the weekend. In addition,  moisture will also be on the rise leading to higher rain and  thunder chances. Any showers and storms will be capable of causing  hazardous marine conditions 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.    $$
