On Wednesday night, a powerful hail storm hit the Red Rocks Park and Amphitheatre in Colorado, leaving nearly 100 people injured. Seven were taken to area hospitals with non-life threatening injuries, including cuts and broken bones, while the rest were treated and released on the scene. The storm caused the concert, which was being held by former One Direction singer Louis Tomlinson, to be cancelled. Concertgoers are advised to take caution and be aware of their surroundings in the event of a storm.
