On April 19, an Oklahoma-based weather photographer, Alexander Spahn, captured a rotating supercell on timelapse.

Supercells are highly organized and long-lived thunderstorms that can produce strong winds, hail, and tornadoes. They are formed when wind shear creates an updraft that tilts the storm, allowing for a persistent rotating updraft called a mesocyclone to develop. This rotation can then lead to the formation of a tornado.

The footage captured by Spahn shows the impressive structure of a supercell, with its rotating updraft and ominous cloud formations over Etowah, Oklahoma, to the southeast of Oklahoma City. According to Spahn, this particular supercell produced "prolific lightning" and spawned "numerous tornadoes."

Supercells are among the most dangerous types of thunderstorms and can cause significant damage and loss of life. Several alerts were issued for these storms the day the footage was captured, indicating the potential for tornadoes to form.

While the footage captured by Spahn is undoubtedly breathtaking, it also serves as a reminder of the power of severe weather. It is essential for individuals and communities to stay informed and stay attentive to alerts, especially when supercells are in the forecast.
