How do flash floods differ from river floods?
Flash floods are floods that develop rapidly with little or no advance warning and often result when a thunderstorm stalls or moves very slowly, causing heavy rainfall over a relatively small area. River floods can result if thunderstorms bring repeated heavy rain to a region for days or weeks. These occur when a major river system rises slowly but floods a large area, whereas a flash flood may devastate a smaller area in minutes to hours.
