A funnel cloud moving over Madison, a suburb in Tennessee, caused electrical flashes and a small explosion seen in a video shared on social media.
Parts of Tennessee were hit by tornadoes and severe storms on Saturday, and at least six people died as a result.
Buildings fell into ruins and communities fell into blackouts in southern US states.
A funnel cloud is different from a tornado because it does not touch the ground. The weather event was also described as a “baby tornado that started to form but never got there”, according to BBC meteorologist David Braine.
