As a result, northeast to east breezes will gradually  slacken through Friday. With that said, there is a potential for  brief nocturnal surges each night through the next several days.  In addition, drier air will be filtering in this evening and  lasting through the end of the week, leading to diminishing rain  chances. A surface high will develop across the Gulf beginning  Friday, which may lead to brief nocturnal wind surges along the  west coast of Florida and into the outer Gulf waters.      The Approximate Shoreward Edge of the Gulf Stream as of November  03, 2026...    57 NM south of Dry Tortugas Light, on Loggerhead Key  34 NM south of Cosgrove Shoal Light, off the Marquesas Keys  25 NM south of Sand Key Light, off Key West  17 NM south of Looe Key, off Big Pine Key  17 NM southeast of Sombrero Key Light, off Marathon  28 NM south-southeast of Alligator Reef Light, off Islamorada  26 NM southeast of Molasses Reef Light, off Key Largo  12 NM east-southeast of Carysfort Reef Light, off Ocean Reef    Gulf Stream Information Courtesy of the National Weather Service in  Key West, using data from RTOFS and NASA SPoRT SST.    $$
