A break in the rain

Lightning Safety Awareness Week is June 20-26, 2010. Lightning is the second greatest cause of storm-related deaths in the U.S., killing more than tornadoes or hurricanes.  Lightning also inflicts life-long debilitating injuries on many more than it kills.

NO PLACE OUTSIDE IS SAFE NEAR A THUNDERSTORM!

Go inside if you hear thunder, but keep away from corded telephones, electrical appliances, and plumbing.  The second safest place is a vehicle with a metal roof and metal sides.
