Lightning Safety

  • There are an estimated 25 million cloud-to-ground lightning flashes each year in the United States, nearly 800,000 of which occur in Illinois alone. 

  • Lightning can be fascinating to watch, but it is also extremely dangerous – it is the underrated killer.

  • Each year in the United States, more than 1,000 people are struck by lightning.

  • The 10-year average was around 55 fatalities each year when Lightning Safety Awareness Week began in 2001. The 10-year average has now dropped to around 23 deaths per year.
