What is a flash flood?

Imagine lookin' up and seein' a HUGE storm movin' in! It starts with HEAVY RAIN, where water falls so fast it's like the clouds are dumpin' out a whole bathtub at once! Now, usually, the dirt drinks up water like a sponge, but when there's HARD GROUND, it's like tryin' to pour water on a sidewalk—it just can't soak in fast enough. Since it can't go down, the water starts FAST RUNOFF, zoomin' downhill in big, splashy sheets! All that extra water bunches up in low spots, causin' RISING WATER that fills up paths and streams way quicker than usual. When all that water hits at once, it becomes a FLASH FLOOD! It's a sudden, powerful rush of water that can even move big things like cars or rocks! It's super important to stay on high ground when things get this rainy. Tiny Concepts.
