The most common and dangerous misconception about lightning is when a storm has cleared the area. Clear skies with little or no rain does not mean the area is safe! LIGHTNING STROKES CAN EXTEND 6 TO 10 MILES from the edge of a storm.
Over 30% of all lightning victims are struck before a storm arrives. 60% of all victims are struck after a storm has passed. LIGHTNING STROKES EXTEND FAR BEYOND YOUR ABILITY TO HEAR THE THUNDER. You are still in danger even under a clear sky. Advanced warning through technology is the only defense against the dangers of lightning from an approaching storm.
About 75% of people who are struck by lightning are struck with blue sky overhead! This is because a storm system can generate lightning that can injure or kill even when it is ten miles away.
Every year, about 200 people are killed and 700 people injured by lightning--more than floods, hurricanes, and tornadoes combined.
Thunder Bolt should be standard equipment for anyone at work or play outside, or anyone responsible for those who are.
