beginning to end. if you look down here, you'll see a brown line. it starts with debris field going in this direction. that is actually the tornado's trail. it's going to get much more dramatic as we get near a populated area. you can trace with your finger a line where the torrent went. the path is the obvious. it's about a block and a half wide. you notice it by seeing everything that's destroyed. everything that looks like paper on the ground, they are homes, timber, roofs, cars. 16 minutes. that was the warning window before it touched down. then a ten minute window during which it went from heavy wind to destroying everything in its path. >> oh my god! >> this is where the tornado was. look at the difference between life and death, between losing everything and losing nothing.
