What are Flash Floods?

Flash floods are sudden and rapid floods that occur with little to no warning. They are typically caused by intense rainfall over a short period, overwhelming the capacity of the local drainage system or natural watercourses. The water accumulates quickly, resulting in a swift and powerful surge of water that can be destructive and dangerous. Flash floods can occur in various environments, including urban areas, canyons, and low-lying regions. Due to their sudden onset and fast-moving nature, they pose significant risks to life, property, and infrastructure. Prompt action and preparedness are crucial in mitigating the impact of flash floods.
