  • 2. On Monday, October 24, 2005, Hurricane Wilma made landfall in Florida. It was the most intense hurricane ever recorded in the Atlantic basin, and the fourth most costly storm in U.S. history. Damage in Florida alone totaled more than $26 billion. In some areas, power was out for two weeks. At the law firm Quarles & Brady LLP, Naples office and Hurricane Wilma.
