Lightning Safety Tips
"If you can see it (lightning), flee it."
"If you can hear it (thunder), clear it."
Seventy percent of all lightning strikes occur in the mid-afternoon hours.
A natural instinct is to take shelter under a tree, which is the worst thing you can do. Of all lightening strikes, 25 percent of all people killed are standing under a tree when they get hit. This is because the positive charges on the ground shoot up to meet negative charges in the thundercloud. They take the quickest route up, which is usually a tree.
About 100 people are killed every year in the United States by lightning.
Getting struck by lightning can pack a punch. A bolt can contain up to 100,000 volts of electricity.
