Brutal cold and fierce winds kept highways treacherous across large parts of Minnesota on Friday, one day after a snowstorm socked much of the state with several inches of snow.
Black ice, often nearly invisible or concealed under new snow, led to hundreds of collisions, cars in ditches and heart-stopping close calls.
At least one person was killed late Friday morning in a head-on crash between a pickup and semitrailer truck on icy Hwy. 61 in Wabasha County, where 8 inches of fresh snow fell Thursday.
In areas both rural and metro, the frigid weather reduced the effectiveness of road chemicals.
Relentless winds formed and re-formed drifts on country roads, and in parts of the city, plows and shovelers were running out of room to stash the snow. Much of the state was under a windchill advisory until 9 a.m. Saturday.
The situation remained especially perilous in western Minnesota. While blizzard and storm warnings were lifted Friday and several closed roads were reopened, the state Department of Transportation warned motorists to use extreme caution in the region.
Late Thursday, Gov. Tim Walz ordered the National Guard out to rescue stranded motorists in Renville County in western Minnesota and to open the Olivia Armory as a shelter.
"Two rescue missions were completed during the night, with 8 people being brought safely back to the armory in Olivia where they joined another 10 stranded motorists who had been brought there," the Sheriff's Office said in a Facebook post.
