"In a typical year, lightning kills 50-100 people and injures 10 times as many. The temperature in a bolt of lightning can reach 50,000 degrees Fahrenheit in a fraction of a second. When a thunderstorm finally moves away, it is tempting to run back out to what you were doing before the storm. However, lightning originating at the top of a thunderstorm, the anvil, can strike miles away from the storm, so wait awhile.This type of lightning is typically positive lightning, called that because it originates a the top of the thunderstorm in a region that is positively charged. Since a lighting stroke that starts out that high must travel a long way to reach the ground, you would expect it to have more energy.Indeed, positive lightning can have ten times the energy of the more common negative stroke. Because of this hazard, the newest safety guidelines suggest allowing much more time and distance than previously believed between the storm and your location or activity to feel confident that it is safe."
