What You Can DO!
Before the storm…
- Know the county in which you live and the names of nearby major cities. Severe weather warnings are issued on a county basis
- Check the weather forecast before leaving on extended periods outdoors
- Watch for signs of approaching storms
- Postpone outdoor activities if thunderstorms are imminent
When Thunderstorms Approach….
- Remember: if you can hear thunder, you are close enough to the storm to be struck by lightning
- Move to a sturdy building or car. Do not take shelter in small sheds, under isolated trees
- Use phones only in an emergency
- Do not take a bath or shower
- Turn off electrical appliances
- Get to higher ground if flash flooding or flooding is possible
If Caught Outdoors and No Shelter is nearby…
- Find a low spot away from trees, fences, and poles
- Make sure the place you pick is not prone to flooding
- If you are in woods, take shelter under shorter trees
- If you are boating or swimming, get to land and find shelter immediately!
If you feel your skin tingle or you hair stand on end, squat low to the ground on the balls of your feet. Place your hands on your knees with your head between them. Make yourself the smallest target possible, and minimize your contact with the ground.
