According to the NWS report issued Tuesday, the Custer County twisters stayed on the ground longer and caused more damage. They were both rated as EF-1 tornadoes with peak winds estimated at 104 miles per hour, and each had a path of over five miles.

The Custer County Sheriff’s Office earlier reported extensive damage to trees and power poles across Custer State Park, though there were no injuries reported. The NWS said in addition to the tornadoes, powerful straight-line winds of up to 70 miles per hour and half-dollar size hail were also responsible for some of the damages.

The tornadoes in Perkins County passed over open land and did not cause any damage, according to the NWS. They were not issued an EF rating.
