Longest megaflash lightning record: 477 miles over 3 states


  • A bolt of lightning that stretched nearly 500 miles across three states is the new record holder for longest flash

USA – A lightning bolt that spanned over 500 miles across three states in the United States has set a new world record for the longest flash.

According to the World Meteorological Organization, the single flash will reach 477.2 miles (768 kilometers) across Texas, Louisiana, and Mississippi in April 2020. That broke the previous record of 440.6 miles set in Brazil in 2018. (709 kilometers).

In addition, in 2020, a single lightning flash over Uruguay and northern Argentina lasted 17.1 seconds, breaking the previous record of 16.7 seconds.

Both flashes were cloud-to-cloud so no one was in danger.

They were spotted by NOAA’s GOES-16 satellite, CNN reported.

Normally, lightning does not travel more than 10 miles and lasts less than a second, according to Arizona State University’s Randall Cerveny, the meteorological organization’s chief of records confirmation.

“These two lightning flash records are absolutely extraordinary,” Cerveny said in an email.

Both were cloud-to-cloud, several thousand feet above the ground, so no one was in danger, he said.

These records, which are not linked to climate change, were spotted and confirmed thanks to new satellite tracking technology. Both regions are two of the few places in the world prone to the type of intense storms that can produce what are called “megaflashes, ” Cerveny said.

“Environmental extremes are living measurements of the power of nature, as well as scientific progress in being able to make such assessments,” said Professor Randall Cerveny, rapporteur of Weather and Climate Extremes for the WMO.

According to USA TODAY, “It is likely that even greater extremes still exist, and that we will be able to observe them as lightning detection technology improves.”

Typically, lightning flashes last less than a second and don’t stretch more than 10 miles.
