What is Flash Flooding?
Flash flooding occurs when excessive water fills normally dry creeks or river beds along with currently flowing creeks and rivers, causing rapid rises of water in a short amount of time. They can happen with little or no warning. … During heavy rain, the storm drains can become overwhelmed and flood roads and buildings.
Flash flooding can occur within a few minutes or hours of excessive rainfall, a dam or levee failure, or sudden release of water…. Most flash flooding is caused by slow-moving thunderstorms with heavy rain downfall, thunderstorms repeatedly moving over the same area, or heavy rains from hurricanes and tropical storms.
