A flash flood describes when there is heavy rain and rapid flooding in a short period, usually less than six hours. They happen within minutes or hours of excessive rain. A flash flood is also possible even if it doesn't rain because a failed dam could cause one.
According to the National Weather Service, flash floods usually include raging torrents that sweep up items.
