BOONE, Iowa—The improvement in travel conditions was the result of the snow moving away from central Iowa. Strong winds continue to cause quite a few problems for road crews and Boone County Emergency Management Coordinator Dave Morlan said the icing that occurred when the snow began falling Wednesday evening is a bigger problem. He says once the snow is moved away, there could be as much as an inch of ice. Earlier Thursday, Morlan said people had been able to travel US Highway 30, even though travel was not advised by the Iowa Department of Transportation. Many encountered quite a bit of ice. The Boone County Sheriff’s Department was very busy, searching for missing vehicles and responding to more than a dozen calls during the Blizzard. In most cases, those that were stranded were not prepared for the weather, with no winter survival materials, shovels or blankets. Authorities did not report any serious problems. Boone Public Works is continuing the city’s Snow Ordinance which prohibits the parking of vehicles on city streets during snow removal.
