A flash flood is a rapid and intense flood that occurs within six hours of heavy rainfall or other events, such as dam breaks. These floods can happen suddenly, often with little warning, and can lead to dangerous conditions. They typically occur in areas with steep terrain, urban environments, or near rivers and streams. Flash floods can cause significant damage to property and infrastructure, as well as pose serious risks to life. They can wash away roads, vehicles, and even entire buildings. It is important for people in flood-prone areas to stay informed about weather conditions and to have an emergency plan in place.
