According to the National Oceanic and Atmospheric Association (NOAA), about 25 million cloud-to-ground lightning strikes occur each year in the United States. More than 400 people are struck by lightning every year; about 70 die, while others are left with permanent neurological damage.
Lightning victims include campers and hikers; sports team participants and coaches; and outdoor workers, like the four workers who were seriously injured in a lightning strike in Arkansas in 2014.
