I can't imagine that type of rainfall rate. The power of a flood is just as mesmerizing to me as a tornado. It has a roar of its own, pushing houses off of foundations, picking up cars and carrying them for miles, and lifting the heaviest of objects. It is amazing watching a three-foot wide creek become a quarter-mile wide whitewater river, its distinctive silty smell annoucing its presence as you approach. Being close to a rushing flash flood is a chase experience that for me rates right up there with a hurricane, tornado and intense lightning storm. Unfortunately they have a tendency to be more deadly and more destructive than their wind-based counterparts.
