Watch: Breathtaking formation of a supercell storm
Storm chasers shared spectacular time-lapse video showing a massive supercell thunderstorm taking shape.
The video was posted online by Basehunters, a storm chasing team originally based in Norman, Oklahoma with members in several states.
The time-lapse video shows a supercell forming Saturday, May 18, 2014 in northeastern Wyoming.
The National Weather Service says supercells appear as “a very tall storm cloud that has an anvil and stretches as far east as you can see.” Supercells are the least common type of thunderstorm but have “a high propensity to produce severe weather” including large hail, damaging winds and tornadoes.
