Part of the 2023 Atlantic hurricane season

Hurricane Idalia was a powerful and destructive Category 4 hurricane that caused significant damage across parts of the southeastern United States, especially in North Florida, in late August 2023. The ninth named storm,[a] third hurricane, and second major hurricane of the 2023 Atlantic hurricane season, Idalia formed from a low-pressure area that crossed Central America from the eastern Pacific Ocean. Gradual development ensued as it meandered in the western part of the Caribbean Sea; the system was upgraded to a tropical depression on August 26, 2023, and strengthened into a tropical storm a day later, receiving the name Idalia. It traversed the Gulf of Mexico where it underwent rapid intensification, briefly becoming a Category 4 hurricane prior to making landfall in the Big Bend region of Florida at Category 3 strength on August 30. Idalia remained a hurricane as it moved through Northern Florida and crossed into Southeast Georgia; it then pushed into the Carolinas as a tropical storm. On August 31, Idalia emerged into the Atlantic, where it transitioned into a post-tropical cyclone that same day. Later, it passed south of Bermuda, made a counterclockwise loop, then meandered off the coast of Nova Scotia while winding down.

Idalia caused significant damage to thousands of homes, businesses, and other infrastructure along its inland path, primarily in Florida, where winds and the resulting floodwaters were highest. Its storm surge was record-breaking from the Big Bend region south to Tampa Bay. The system also spawned a tornado outbreak with around 12 confirmed tornadoes. Idalia was the most powerful hurricane to hit Florida's Big Bend region since Hurricane Easy in 1950 and the third strongest landfalling hurricane in the region after the 1896 Cedar Keys hurricane and the aforementioned Easy.[1] Five people died in storm-related incidents in the two states. Early estimates placed insured losses at $2.2–5 billion. The hurricane's remnants produced dangerous rip currents across the Eastern United States during Labor Day Weekend, resulting in several additional deaths and numerous rescues.
