Thunderstorm
If there is a flash flood, stay out of low places. Cars should not be driven through water that is flowing over a road or bridge. It might look shallow (not deep), but quickly flowing water can wash a car right off a road or a bridge. It only takes two feet of water to float most cars. Also, the road under the water might already have been washed out, leaving a deep hole. A flash flood can easily turn over a car and trap everyone inside. So, if your car stops in flood waters, get out as fast as possible and run to higher ground. Nearly half the people who die in flash floods in the United States die inside cars.
