Hear the Roar of the May 20th Moore, Oklahoma Tornado

NORMAN, OK -- Plug in a good pair of headphones or speakers and turn the volume up loud (the louder the better). There are no sirens or other loud noises to worry about. In the background, you will hear a low pitched growl/roar sound (similar to a train in the distance), sometimes sounding like light wind noise across the mic. That is the tornado you are hearing as it crossed Interstate 35. You can hear it the best in the last 5-6 seconds of the video. This video was shot from my house on the east side of Norman, about 10 miles from the tornado. It was much louder in real life, but this camera is not the best at capturing those low-pitched tones.
