Thunder and Lightning

1) Keep an eye on the sky. On a hot day, cumulus clouds build up. They grow larger, towering higher and higher. They darken. The top of the clouds may be spread out by wind at high altitudes. As clouds develop, particles in the clouds become charged with electricity.When the charges overflow, they make a lightning flash.
2) Lightning may go from one part of a cloud to another, or from cloud to cloud. It may go from a cloud to earth, or from earth to a cloud.
3) Lightning takes the shortest path. So, it hits the highest object - a tall tree or house, a tower, or a person standing alone in a flat field.

Lightning Strikes!
4) Lightning may hit the same place, or the same person, several times.
Ray Sullivan, a retired National Park Ranger, was hit seven times. He has been knocked down, picked up and thrown into the air; he has lost his shoe and a toenail, and he can't hear as well as he used to. But he's lucky to be alive!

Thunder and Lightning Occur Together
5) The light reaches you at once. Sound takes some time to reach you. Usually you see the lightning stroke before you hear the thunder.
6) As soon as you see the lightning, count the seconds until you hear the thunder. If it takes three seconds to hear the thunder, the storm is about a kilometer away.
7) If you see lightning and hear thunder at just about the same moment, watch out! The storm is right above you, only a few hundred meters away.

What To Do When You are Outside
8) don't go into a shed that stands alone.
don't go under a large tree that stands alone.
don't be higher than your surroundings.
don't stand on a hilltop.
don't stay out in a boat.
don't carry anything made of metal, and don't be near anything made of metal.
don't lie down because because wet ground can carry electricity.

9) get inside a hard-topped car.
crouch on your knees and bend over when you are in a field.
