Almost 500-Mile-Long Lightning Bolt Crossed Three US States

An almost 500-mile long bolt of lightning that lit up the sky across three US states has set a new world record for longest flash, scientists have confirmed. The BBC reports: The lightning bolt, extended a total of 477.2 miles (768 km) and spread across Mississippi, Louisiana, and Texas. The previous record was 440.6 miles (709 km) and recorded in Brazil in 2018. Lightning rarely extends over 10 miles and usually lasts under a second. Another lightning flash recorded in 2020 -- in Uruguay and Argentina -- has also set a new record for duration at 17.1 seconds. The previous record was 16.7 seconds.

According to the WMO, both records took place in areas prone to intense storms that produce 'megaflashes,' namely the Great Plains region of the United States and the La Plata basin of South America's southern cone. Previously accepted WMO 'lightning extremes' include a 1975 incident in which 21 people were killed by a single flash of a lightning as they huddled inside a tent in Zimbabwe. In another incident, 469 people were killed when lightning struck the Egyptian town of Dronka in 1994, causing burning oil to flood the town.
