were able to save that man after he was filling up bucket after bucket in his car to get that water out of there and save himself today. >> and the dynamics of flash flooding are such that you can literally be driving down the road in rain, right, and then you get a cloudburst and the next thing you now, you're in this situation. >> it can happen in minutes or perhaps you're approaching a bridge that goes over a river, and that river might be right at the cusp of coming over. you never know when that's going to happen or how deep it is. at the beginning of the rescue, we saw the firefighters at the a few fight of the vehicles, and the firefighters are less than ankle deep a few feet away from there. when you drive over a road that has water on it, you are always taking that risk. you don't know how deep that water is. you can't see the bottom of it, and you don't know if that road is intact or it was potentially washed away.
