I–90 is closed north of Sturgis to Sheridan. The bad conditions start just outside Rapid City. One car slid into the guard rail just a mile north of Deadwood Avenue.
And farther up the road near Elk Creek Road ... A car found the center median where it will ride out the storm.
Slow traffic was still moving toward Sturgis but drivers were being warned that the highway was closed ahead.
In Sturgis, some business were closed because of power outages and tree limbs were snapped like twigs under the heavy wet snow.
