NATIONAL WEATHER SERVICE ILLUMINATES LIGHTNING SAFETY INFORMATION
Cloud-to-ground lightning strikes within the United States an average of 25 million times every year. A single bolt, with a length that can exceed five miles and a width of one to two inches, can generate 100 million electrical volts and a temperature near 50,000 degrees Fahrenheit. "Lightning is a potential hazard to people outdoors and indoors and results in millions of dollars in economic losses," said Brig. Gen. David L. Johnson, U.S. Air Force (Ret.), director of the NOAA National Weather Service. "Lightning kills an average of 67 people in the United States each year and can result in property loss, damage to aircraft and electronics, and can be the spark that ignites devastating wildfires." Exceeding the number of fatalities are the estimated 600-700 lightning survivors that are left with debilitating health effects each year. "While about 90 percent of those struck by lightning survive, they frequently have permanent after effects such as chronic pain, brain injury and thought processing problems," said Mary Ann Cooper, professor, Department of Emergency Medicine, University of Illinois.
"Casualties are more likely to occur during the summer months and in open areas such as golf courses and playing fields, but lightning's deadly strike can hit anytime during the year and in all segments of the nation," said John Jensenius, a lightning safety expert at the NOAA National Weather Service Weather Forecast Office in Gray, Maine. The NOAA National Weather Service is the primary source of weather data, forecasts and warnings for the United States and its territories. The NOAA National Weather Service operates the most advanced weather and flood warning and forecast system in the world, helping to protect lives and property and enhance the national economy. NOAA, an agency of the U.S. Department of Commerce, is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and providing environmental stewardship of the nation's coastal and marine resources.
