Almost 500-mile-long lightning bolt crossed three US states
NEW YORK -
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 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.
"These are extraordinary records from lightning flash events," Professor Randall Cerveny, the WMO's rapporteur of weather and climate extremes, said.
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.
Professor Cerveny added that greater extremes are likely to exist and are likely to be recorded in the future thanks to advances in space-based lightning detection technology.
The WMO warned that lightning was a hazard and urged people in both regions and around the world to take caution during storms.
"These extremely large and long-duration lightning events were not isolated but happened during active thunderstorms," lightning specialist Ron Holle said in a WMO statement.
"Any time there is thunder heard, it is time to reach a lightning-safe place".
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.
The WMO notes that the only lightning-safe locations are "substantial" buildings with wiring and plumbing, rather than structures such as bus stops or those found at beaches.
Fully enclosed metal-topped vehicles are also considered reliably safe.

A resilient Germany is weathering the energy crunch
BERLIN - German industry and society are once again proving much more resilient and adaptable than certain people feared. Horror scenarios of a dangerous energy rationing or a massive slump in our economy have often been bandied about. But we are nowhere near that. With a challenging year just behind us, this is good news — not only for Germany, but also for Europe.
Companies and households reacted swiftly to the sharp increases in energy prices. They installed more efficient heating or production facilities, switched to alternatives and imported intermediate products. The results are encouraging: German households and businesses have reduced…
