Storm chasers trapped by flooding as tornado forms overhead!

On June 16, 2010, a prolific tornadic supercell sat nearly stationary over Dupree, South Dakota, producing possibly a dozen or more tornadoes! Storm chasers, law enforcement officials and locals became trapped by flash flooding on HWY 212. Unfortunately, a strong couplet formed over the top of them as they sat helpless, producing winds in excess of 90 MPH!! Note the power poles at the beginning of the video and at the end. The power pole in front of the state trooper snapped off to the north while the other pole fell to the south!
