The new record for the longest lightning bolt is insane

On Halloween in 2018, a colossal lightning flash streaked across the Brazilian sky. 

A National Oceanic and Atmospheric Administration (NOAA) satellite captured the “megaflash,” and the World Meteorological Organization (WMO) announced Wednesday that this mighty bolt stretched some 440.6 miles (give or take five miles) across the sky. That’s about the distance between Washington, D.C. and Boston.

The WMO also certified the greatest duration for a flash, at 16.73 seconds. That extreme event happened last year over Argentina. 

“These are extraordinary records from single lightning flash events,” Randall Cerveny, the chief rapporteur of weather and climate extremes for the WMO, said in a statement. “Environmental extremes are living measurements of what nature is capable, as well as scientific progress in being able to make such assessments. It is likely that even greater extremes still exist, and that we will be able to observe them as lightning detection technology improves.” Read more…
