The April 2011 derecho and tornado outbreak was a large-scale damaging wind and tornado outbreak that affected the South and Eastern parts of the United States. The system produced a large serial derecho windstorm that caused thousands of reports of wind damage and several embedded tornadoes. Power outages were extensive across the area and tree damage was severe. Several people were killed and injured by falling trees and branches as the storm passed through. Damaging tornadoes touched down in Arkansas, Kentucky, and Mississippi. The storm continued into the early hours of the morning causing more wind damage along the East Coast along with a few more tornadoes. It is reportedly one of the most prolific damaging wind events on record.
