A South Dakota
tornado stood still for at least half an hour Saturday afternoon, producing a mesmerizing sight for miles into northern Nebraska.
The tornado first developed around
2:30 p.m. MDT Saturday June 29, 2019 near
Allen, South Dakota, about 85 miles southeast of Rapid City.
Roughly 30 minutes after the tornado was first reported, it was still in progress in western Bennett County. Unlike most tornadoes, though, it had barely moved.
One house was damaged but there were no reports of injuries, according to the South Dakota Highway Patrol and Bennett County Sheriff's Office.
Meteorologists from the National Weather Service will survey the damage on Sunday to estimate the tornado's intensity and path.
The relatively flat, treeless terrain allowed many to view the tornado from miles away.
For some, the view resembled a landspout tornado, with a narrow funnel near the cloud base and a hose of churned-up dust, giving the tornado a two-part look.

"It's beautiful, You could see the parent thunderstorm's broader rotation, what meteorologists call the mesocyclone, swirling at the base of the cloud from which the almost perfectly vertical tornado extended."
