Governor Dayton has issued a retroactive executive order authorizing the use of the National Guard Armory in Olivia as shelter after some stranded motorists had to stay there during Sunday night’s blizzard. Dayton issued the written order Tuesday after he verbally authorized the use of National Guard resources on Sunday. The blizzard that struck most of Minnesota’s southern half on Sunday hit particularly hard in Renville County. Dozens of stranded travelers were forced to spend the night in Olivia due to several major highway closures in the area, and the town’s one hotel filled up quickly. None of the motorists are still stranded.
