— Prepare for High Winds: If you have time, secure lawn furniture, outdoor decorations, trash cans, hanging plants and anything else that can be picked up by wind.
Before Lightning Strikes
Keep an eye on the sky. Look for darkening skies, flashes of light or increasing winds. Listen for the sound of thunder.
If you can hear thunder, you are close enough to the storm to be struck by lightning. Go to safe shelter immediately. The National Weather Service recommends staying inside for at least 30 minutes after the last thunder clap.
When Storm Approaches
Find shelter in a building or car. Keep car windows closed and avoid convertibles.
Telephone lines and metal pipes can conduct electricity. Unplug appliances. Avoid using the telephone or any electrical appliances. (Leaving electric lights on, however, does not increase the chances of your home being struck by lightening.)
Avoid taking a bath or shower HYPERLINK "http://" , or running water for any other purpose.
If Caught Outside
Go to low-lying, open place away from trees, poles or metal objects. Make sure the place you pick is not flooding.
Make yourself the smallest target possible. Squat low to the ground. Place you hands on you knees with your head between them.
If you are in the woods, take shelter under the shorter trees.
If you are boating or swimming, get to land and find shelter immediately.
If Someone Is Struck By Lightning
People struck by lightning carry no electrical charge and can be handled safely.
Call for help. Get someone to dial 9-1-1 or your local Emergency Medical Services (EMS) number.
Give first aid. If the heart has stopped beating, a trained person should give CPR.
