(KSFY) - Officials say Interstate 90 westbound has been reopened and motorists are advised a South Dakota Highway Patrol trooper will direct traffic onto County Road 14-16 at exit 84 until crews can get a lane open to go around the remaining crashed semi.
I-90 westbound was closed earlier today from Exit 110 to Exit 78.
Visibility in the west is improving, but roads are still icy and motorists are reminded to slow down, turn off cruise and alter travel plans as necessary until the storm moves out of the state.
State transportation officials temporarily closed westbound Interstate 90 in western South Dakota because of some crashes involving semis as winter weather bears down on the region.
A no travel advisory was issued by the Department of Transportation as a storm with snow and strong winds moves east. A blizzard warning was in effect for the northeastern part of the state. Officials say semi drivers with their tall trucks are especially vulnerable in high winds.
Motorists are being asked to postpone travel plans until the storm passes and the winds decrease later tonight. The conditions caused schools in the region to cancel or delay classes Monday.
The University of North Dakota was the latest school to announce it was closing at 12:30 p.m.
Mild temperatures will give way to colder conditions in South Dakota with some schools getting ahead of the storm and canceling classes.
Rain will turn to snow later Monday and cause some dangerous travel conditions, especially in central and northeast South Dakota. The National Weather Service issued a blizzard warning for Aberdeen, Britton and Watertown. Elsewhere a winter storm warning or winter weather advisory was in effect for later Monday.
Aberdeen, Britton-Hecla, Groton, Sisseton and Webster schools are among those closed Monday. Anywhere from 1 inch (25 millimeter) to 5 inches (127 millimeters) of snow is expected to fall with gusty winds.
