The longest lightning bolt in the world covered a distance of almost 200 miles across the state of Oklahoma on June 20, 2007.
The lightning bolt was said to travel 199.5 miles
according to WMO. The longest duration for a single flash of lightning was also confirmed which happened Aug.30, 2012 in Provence-Alpes-Côte d’Azur, France, which had a flash for 7.74 seconds.
In the U.S. alone, lightning strikes about 25 million times a year which kills about an average of 49 people and injures hundreds, according to the National Weather Service. This year, lightning has so far killed 35 people
in the U.S., which in turn makes 2016 the deadliest year for lightning-related fatalities. However, improved sensing technologies have resulted to better safety protocols and warning systems, WMO said.
Randall Cerveny, chief Rapporteur of Climate and Weather Extremes for WMO said
, “The end result reinforces critical safety information regarding lightning, specifically that lightning flashes can travel huge distances from their parent thunderstorms. Our experts’ best advice: when thunder roars, go indoors.”
