The blowing and drifting of snow makes retrieving stuck vehicles in ditches and medians extremely dangerous, especially with the reduced visibility. Tow bans are currently in effect for Cass, Adair, Shelby, Pottawattamie, Mills, Fremont and Dallas Counties in the KJAN listening area. That means tow services will not be able to help your vehicle until Friday, at the earliest, unless otherwise mentioned. Travel is not advised in Shelby and other area counties today unless absolutely necessary.
