4 tornado touchdowns reported in Denver area

A super cell thunderstorm dropped large amounts of hail and produced several tornadoes that swept through the Denver area Wednesday, weather officials said. The National Weather Service reported four tornado touchdowns in Watkins, East Denver and Aurora, Colo. "This thing is spinning up multiple tornadoes," witness Jeff Piotrowski told CNN. "There were tornadoes on the outer ring of the circulation, ... and then there's the main tornado vortex closer to the storm."
