Since the last update about 20-30 minutes ago, more counties have gone under tow bans including Hardin, Black Hawk, Grundy, Bremer, Butler and Franklin counties. Travel is not advised in a portion of eastern Iowa around Cedar Rapids and Iowa City at this time, but it is advisable that travel should be restricted to emergencies only over the entire state. Blowing and drifting snow will continue through the rest of the day and into tonight. There have been numerous accidents and roads being blocked by these conditions. Stay safe at home.
