Road Weather Information System

Montana's Road Weather Information System (RWIS) consists of 73 sites across the state. Road weather information systems provide real time information via standard communication tools (phone lines and computer network) statewide. These sites are located in strategic locations to provide accurate real time weather information.

This information allows MDT's Maintenance Division to schedule personnel and equipment based on current weather and pavement surface conditions. Real time weather information improves response time, increases winter maintenance efficiency and minimizes the traveling public's exposure to hazardous weather related roadway conditions.
