Brendan Loy, who was one of my go-to guys during Katrina, has a compilation of videos and other information on the tornadoes that have killed over 200 people so far.

Edit: I was watching that second video, and staring at that light pole right in the center of the tornado. And that light pole stayed, minute after minute, right in the center of that tornado. Clue: when a moving object isn’t changing its azimuth and getting larger, you’re next.
