A video shows a giant supercell moving over a rural road.
A video purportedly showing a “live” view of a huge, rare supercell thunderstorm moving across a rural road was viewed millions of times after it was posted on 20 July 2017 to the Facebook page “Newsfeed”:
This footage did not show a “live” video of a storm, and the biggest giveaway thereof was that the storm did not move from its original location at any time during the four-hour-long stream.
The main reason for the storm’s static appearance, of course, is that this footage was actually based on a photograph, taken by storm chaser and photographer Marko Korosec, of a supercell near Murdo, South Dakota on 19 June 2015.
Korosec explained in a Facebook post that this “tornadic supercell” was one of the best he’d ever seen:
This static photograph was later animated by Jonathan Wennstrom, who posted a cinemagraph of the storm to his Instagram page on 2 July 2017.
