Montana Department of Transportation RWIS

Montana's Road Weather Information System (RWIS) consists of strategically located sites across the state which 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.
