THUNDERSTORM FACTS

Garden variety thunderstorms are common occurrence during the summer over the mountains. Though they may appear benign and harmless, even the smallest storm contains lightning which is dangerous. Lightning results from the buildup and discharge of electrical energy within a storm cloud. Here are a few facts about lightning:

1. Most lightning occurs within the cloud or between the cloud and ground.
2. The air near a lightning strike is heated to 50,000 degrees F, - much hotter than the sun.
3. The average flash could light a 100-watt light bulb for more than 3 months.
4. In the Western U.S., the largest danger from lightning is fires.
5. Your chances of being struck by lightning are estimated to be 1 in 600,000.
6. Lightning can and sometimes does strike the same place twice.
   
7. If caught outside during a thunderstorm and your hair feels like it's standing on end, lightning may be about to strike you. Drop immediately to the ground, forming a ball with your body. Stand on the balls of your feet. Duck your head to your knees.
