Flash floods kill more people than tornadoes, hurricanes or lightning.

Flash flood creates a rush of moving water that can sweep a grown man office feet, a car off the road and even your entire home off its foundation.

When the ground becomes so saturated that water can no longer seep into the soil, it begins to run off quickly into rivers and streams, and this causes a rise in water in a flash.

Densely populated areas have an extremely high risk of flash flooding, with the additional concrete and less grassy areas for the water to soak into the soil, and they can see flash flooding very quickly in a mountainous terrain.

The combination of gravity, plus the easy runoff, can lead to catastrophic flooding.

 When all of that water spun gold into rivers, creeks and even the valley's remember flash letting can happen in the blink of an eye.
