Synopsis For Keys Coastal Waters From Ocean Reef To Dry Tortugas
Forecast as of 10:26 am EST on November 20, 2008
Synopsis... A high pressure ridge over the northern Gulf of Mexico will move southward and weaken today...resulting in slackening breezes across the Florida Keys and adjacent coastal waters. Another high pressure system building down from Canada will send yet another weak cold front and wind surge through the Florida Keys Friday night. As a result...fresh to strong north to northeast breezes will prevail Friday night through the weekend. The approximate shoreward edge of the Gulf Stream as of November 19... 23 nm south of Dry Tortugas light...on Loggerhead Key. 5 nm south of Cosgrove Shoal light...off the Marquesas Keys. 5 nm south of Sand Key light...off Key West. 7 nm south of Looe Key...off Big Pine Key. 8 nm south of Sombrero Key light...off Marathon. 8 nm southeast of Alligator Reef light...off Islamorada. 9 nm southeast of Molasses Reef light...off Key Largo. 8 nm east of Carysfort Reef light...off Ocean Reef.
