If you have lived in Western Colorado very long, then you know how uncommon it is for us to get heavy rain. Something even more uncommon is capturing an oncoming flash flood on video. Check out this footage taken of a flash flood coming down the Colorado National Monument..

Flash floods occur when a sudden amount of water is dumped in a place not equipped to handle it. They are especially dangerous due to the fact they typically occur in situations where people are not prepared to deal with them.
