SIOUX FALLS — Whether by air or land, travel conditions continue to deteriorate across South Dakota, as an ongoing winter storm and blizzard conditions persist.

After first delaying dozens of flights out of the city, the Sioux Falls Regional Airport announced that it will be closed from 1 p.m. Thursday, Dec. 22, until 6 p.m. Friday, Dec. 23. According to the airport's website, 35 departures and arrivals have all been canceled. The closure could be extended if conditions do not improve.

On the roads, the South Dakota Department of Transportation (SDDOT) announced that Interstate 90 will also close to traffic from Chamberlain to Sioux Falls at 5 p.m. Thursday. The road remains closed from Rapid City to Chamberlain due to sustained high winds causing blizzard-like conditions. Officials expect the closure to remain in effect into Friday.

The travel impacts extend beyond the interstates and on to most roads in the state, where high winds and low visibility have stranded motorists across the state. Multiple "no travel advisories" and "road impassable conditions" are in place on South Dakota's 511 travel website. The SDDOT advises motorists not to attempt to use secondary roads to avoid interstate closures.

The National Weather Service expects a blizzard warning to remain in effect through Friday.
