A flash flood is a sudden and intense flood that occurs within six hours of heavy rainfall or other events, such as dam breaks. These floods can happen quickly, often with little warning, and can lead to dangerous conditions. They typically occur in areas with steep terrain, urban environments, or regions with poor drainage systems. Flash floods can carry debris, rocks, and other materials, making them particularly hazardous. They can overwhelm rivers, streams, and drainage systems, leading to significant property damage and posing risks to life. Awareness and preparedness are crucial for safety during such events, especially in vulnerable areas.
