In the event of a thunderstorm and you are in or around water, get to land immediately and find shelter. If you are in an open field and a thunderstom hits, find a low spot away from trees, fences, and poles. Look for low ground such as a valley or ravine. If this is not possible, crouch down. The worst place to be during a thunderstorm is standing under a tree on a hill.
Some thunderstorms produce strong damaging winds.
If you are outside, head for a strong building. Do not stand by windows. Flash floods can occur anywhere when it rains with little or no warning. Move to higher ground to escape flood water and never camp on low ground. Most deaths in flash flooding occur in automobiles.
