Iowa Department of Transportation (Iowa DOT) provides the Road Weather Information System (RWIS) data as a public service. This information is published automatically and cannot be guaranteed as to accuracy or timeliness. Iowa DOT makes every effort to ensure the accuracy and timeliness of this information; however, it is dependent on several items including the roadside hardware, internet availability, communication networks, and computer equipment, which are beyond the control of Iowa DOT and difficult to predict.
