Effects of Hurricane Irma in Florida
Irma was the first major hurricane to strike the state since Wilma in 2005 and the first Category 4 hurricane to make landfall in Florida since Charley in 2004. The storm made landfall in Florida on the same date as Hurricane Donna, the last Category 4 hurricane to strike the Florida Keys. Irma was only the second hurricane to hit Florida since Wilma, the other being Hermine in 2016. Due to few very intense hurricanes since Hurricane Andrew in 1992, there was concern that many Floridians never experienced or did not recall experiencing a hurricane as strong as Irma was projected to be at landfall, with significant growth in population and assets during the previous 25 years.
2005 Atlantic hurricane season
Hurricane Katrina formed in mid-August over the Bahamas. It became a tropical storm on August 24 and reached hurricane intensity before making landfall in south Florida as a minimal hurricane. A few hours later, the storm entered the Gulf of Mexico and intensified rapidly into a Category 5 hurricane while crossing the Loop Current on August 28. Katrina made landfall shortly after 06:00 CST on August 29 near the mouth of the Mississippi River as an extremely large Category 3 hurricane. Category 5-level storm surges (as the storm had weakened only in the previous several hours) caused catastrophic damage along the coastlines of Louisiana, Mississippi, and Alabama. Within hours, levees separating Lake Pontchartrain from New Orleans, Louisiana were breached by the surge, ultimately flooding about 80% of the city. Wind damage was reported well inland, impeding relief efforts. Katrina is estimated to be responsible for at least $125 billion (2005 USD) in damage, breaking Hurricane Andrew's record in 1992 and making it the costliest natural disaster in U.S. history until Harvey tied it in 2017. It was the deadliest U.S. hurricane since the 1928 Okeechobee Hurricane, killing at least 1,836 people. The 1900 Galveston Hurricane remains the deadliest natural disaster in United States history, with a death toll of approximately 6,000.
