What is a common feature of flash floods?

Rapid flooding is a defining characteristic of flash floods. These events occur quickly, often within six hours of heavy rainfall or sudden water influx, leading to a swift increase in water levels. Unlike other types of flooding that may build up gradually, flash floods can occur with little warning, catching people off guard and making them particularly dangerous. This rapid rise in water is typically due to a combination of factors, such as steep terrain, heavy rain in a short period, or sudden water flow from streams and rivers that cannot handle the volume of water. Understanding this feature is crucial for recognizing potential hazards and taking necessary precautions when severe weather is predicted.
