The latest 511ia.org map from the Iowa Department of Transportation shows (as of 8:45-a.m.), road conditions across western Iowa are deteriorating. Roads that had been partially covered with snow as of 7:15-a.m. are now mostly covered with snow, with bridges and overpasses becoming icy (purple colored roads on the map below). Roads in blue are partially covered with snow, while roads in green are in normal winter driving conditions. (Click on the map for a larger view)
