PIERRE, S.D. (AP) _ State officials have started closing interstates in South Dakota and North Dakota as blizzard conditions move into the states.
Terry Woster with the South Dakota Department of Public Safety says Interstate 90 between Wall and Chamberlain. Interstate 29 has been closed from Watertown, S.D., to Fargo, N.D.
Woster says falling snow and strong winds are combining to create slippery roads and near-zero visibility.
Travelers are advised to delay trips in the direction of the closed highway from either direction until conditions improve.
The high winds are forecast to continue through Sunday and into Monday, so officials say other interstate closures are likely.
In North Dakota, officials have issued a no travel advisory for the southeast portion of the state.
