What is Lightning?


Lightning is a form of electrical discharge between clouds or between a cloud and the ground.
The discharge may take place between two parts of the same cloud, between two clouds, or between a cloud and the ground. Lightning may appear as a jagged streak, a flash in the sky, or in the rarer form of a brilliant ball. Thunder is the sound waves produced by the explosive heating of the air in the lightning channel during the return.

Lightning Specifics

  • Most lightning strikes occur either at the beginning or end of a storm.

  • The average lightning strike is six miles long.

  • Lightning reaches 50,000 degrees Fahrenheit, fours times as hot as the sun's surface.

  • A cloud-to-ground lightning channel can be 2 to 10 miles long.

  • Voltage in a cloud-to-ground strike is 100 million to 1 billion volts.

Did You Know?


  • Lightning is underrated as a risk because it usually claims only one or two victims at a time and does not cause mass destruction of property.

  • Lightning affects all regions. Florida, Michigan, Pennsylvania, North Carolina, New York, Ohio, Texas, Tennessee, Georgia, and Colorado have the most lightning deaths and injuries.

  • Lightning kills more people on an annual basis than tornadoes, hurricanes or winter storms. It is second only to flash floods in the annual number of deaths caused by storm-related hazards.

  • Damage costs from lightning are estimated at $4-5 billion each year in the U.S.

  • Around the earth there are 100 lightning strikes per second, or 8,640,00 times a day.

  • What is commonly referred to as heat lightning, is actually lightning too far away to be heard. However, the storm may be moving in your direction.

  • There are approximately 100,000 thunderstorms in the U.S. each year.

Striking Statistics

  • Americans are twice as likely to die from lightning than from a hurricane, tornado or flood.

  • The Federal Emergency Management Agency (FEMA) estimates there are 200 deaths and 750 severe injuries from lightning each year in the U.S.

  • 20% of all lightning victims die from the strike.

  • 70% of survivors will suffer serious long-term effects.

  • Annually, there are more than 10,000 forest fires caused by lightning.

 

Who's at Risk?


  • 85% of lightning victims are children and young men aged 10-35 engaged in outdoor recreation and work activities outside.

  • 70% of all lightning injuries and fatalities occur in the afternoon.

  • Most lightning deaths involve people working outdoors and outdoor recreationists

  • Lightning in remote terrain creates dangerous conditions. Hikers, campers, backpackers, skiers, fishermen, and hunters are especially vulnerable when they're participating in these activities.

  • Many survivors of lightning strikes report that immediately before being struck their hair was standing on end and they had a metallic taste in their mouth.

  • Long-term injuries from a lightning strike can include memory & attention loss, chronic numbness, muscle spasms & stiffness, depression, hearing loss, and sleep disturbance.
