National Weather Service Key West FL
1246am EDT Wednesday September 28 2022

Marine
Issued at 1241am EDT Wednesday September 28 2022 A Hurricane Warning is in effect for the far western waters, including the western Straits of Florida and the offshore Gulf of Mexico coastal waters surrounding the Dry Tortugas. A Tropical Storm Warning is in effect for the nearshore and offshore waters of the Florida Keys, including the Florida Bay, Bayside and Gulfside waters, Hawk Channel, and the Straits of Florida south of the island chain. A Storm Surge Warning is in effect for the Lower Keys and a Storm Surge Watch is in effect for all of the Middle and Upper Keys, with current coastal flooding and high tides likely to be exacerbated by the passage of potential Major Hurricane Ian on Tuesday and Wednesday.

From synopsis, Major Hurricane Ian is currently moving across the outer western fringes of the western coastal waters, and will continue north to northeastward towards the Florida Peninsula over the next several days. Peak winds and seas will occur through Wednesday morning in the Florida Keys coastal waters. While winds will gradually slacken tomorrow afternoon through Thursday, marine hazards from dangerous seas will continue for several days, particularly for the western marine zones. Mariners should continue to monitor the latest information provided by the National Hurricane Center and the National Weather Service office in Key West. Marine conditions will vastly improve over the weekend, when a weak pressure pattern will promote light to gentle, generally westerly breezes.
