A flash flood is a sudden and rapid overflow of water, usually caused by heavy rainfall or the melting of snow in a short period. These floods can occur within hours of a downpour, often in areas with steep terrain or poor drainage systems. Flash floods can be highly dangerous, as they can wash away buildings, roads, and vehicles, and can result in loss of life. They are unpredictable and can happen quickly, leaving little time for people to evacuate. Flash floods are common in regions with mountainous or hilly terrain where water flows rapidly downhill.
