The Keys sit just feet above sea level, making king tides, storm surge, and tropical systems a constant threat. Sunny-day "nuisance" flooding now happens routinely in low-lying neighborhoods of Key Largo, Marathon, and Key West, while hurricanes like Irma show how exposed the island chain truly is.
Monroe County flooding is unique in Florida — the Keys' highest natural elevation is only about 18 feet, and most populated areas sit just 3 to 6 feet above sea level. Key West king tide flooding now closes streets in Old Town and the Truman Annex on a predictable monthly cycle, and Hurricane Irma's 2017 storm surge devastated the Lower and Middle Keys around Big Pine and Marathon. Florida Keys flood alerts from Floodi give residents and visitors real-time crowdsourced visibility into flooded sections of US-1, the only highway connecting the islands.
