SIOUX FALLS, S.D. (KELO) — Gusty winds are creating blizzard conditions for much of South Dakota Thursday. 

At 1:30 p.m., emergency alerts were sent to smart phones about snow and high winds making many road blocked.

Nearly the entire state is listed under a blizzard warning, winter storm warning or winter weather advisory until noon Friday.

At 2 p.m., the South Dakota Department of Transportation said it expected Interstate 90 and I-29 closures to remain in place overnight and until wind and snow subside. 

No travel advised remains for many state highways, the DOT says several highways are currently listed as “Road Impassable” on SD511 such as portions of S.D. Highways 34, 44, 45, 47, 49, 53, 63, 240, 1806 and U.S. Highways 14, 18 and 83.

The DOT says when a road is listed as “Road Impassable” travel on the road segment is physically impossible typically due to widespread deep snow and drifts. 

On U.S. Highway 14 west of Pierre, troopers say multiple vehicles are struck and the South Dakota Department of Transportation has deemed the road impassable. 

On Thursday, the South Dakota Highway Patrol has been posting photos of dangerous road conditions across the state.
