The phrase “out of the blue,” which signifies something unexpected, is derived from a perilous weather event known as a “bolt from the blue.” This phenomenon, as described by the National Weather Service, involves a cloud-to-ground lightning strike that appears to come from a clear sky, hence its name. Lightning can strike far from the originating cloud, creating the illusion of sudden lightning. Lightning Safety: Even Routine Tasks like Taking Out the Trash Can Turn Deadly During Thunderstorms Twenty individuals at a beach in Columbia, South Carolina were struck by a “bolt from the blue” on a clear day, as reported by first responders to FOX Weather. Prior to the incident, the NWS office in Columbia had issued a Special Weather Statement warning of a strong thunderstorm approaching western Lexington County with lightning and gusts up to 50 mph. Dispelling Lightning Myths John Jensenius from the National Lightning Safety Council explains that lightning can reach the ground up to 10 miles away from its originating thunderstorm. The NWS has documented lightning strikes extending over 90 miles within a cloud, noted by NWS Severe Weather Program Coordinator Derek Deroche. NOAA and the NWS state that a “bolt from the blue” typically originates from rising warm air in the upper portion of a thunderstorm, traveling horizontally for many miles before striking the ground. Fox Weather Viewing Tips Experts recommend staying indoors during thunderstorms as the best way to remain safe from lightning. Individuals are advised to avoid bodies of water like lakes and beaches during storms. Once inside, keeping away from windows, doors, plumbing, and refraining from showering is essential for safety. Lightning Safety Reminders The NWS suggests waiting at least 30 minutes after the last thunderclap before venturing outside. Lightning strikes over 20 million times in the U.S. annually, resulting in an average of 20 fatalities per year. Source: Bolts from the Blue: Understanding the Dangers of Lightning Strikes
