Causes of Flash Floods
Flash floods can occur when it rains heavily for a short time, often in thunderstorms. β˜”

️ For example, if a storm dumps 3 inches of rain in just a few hours, it can cause a flash flood! Other causes include melting snow, or if water can't drain away quickly, like in cities with many buildings. 🌁

Sometimes, when there’s a dam break, it can suddenly release a lot of water, creating a flash flood downstream. The soil can also become too full of water (saturated), leading to more flooding. Understanding these causes helps us be ready!
