Avalanche control

Learn about our avalanche forecasting and control efforts to keep our transportation system reliable and safe.

Our Avalanche Forecasting and Control team is a dedicated crew of experienced professionals who monitor the weather and snow to determine when avalanches may occur. The crew is split into two regional teams with full-time employees and seasonal employees. The Avalanche Control Supervisor for each team leads the crew throughout the year. Check out a video highlighting their avalanche control efforts.

When conditions indicate an avalanche is imminent, teams employ various methods and tools to bring down unstable snow in a controlled manner. The team works throughout the fall, winter, and spring along Washington's mountain highways.
Our Avalanche Paths are mapped out and tracked in a web mapping application that is publicly accessible. Check out the Avalanche Atlas map page. Forecasting avalanches
Avalanche forecasting determines the potential risk along a particular mountain slope. Avalanche forecasts are based on past, current and forecasted conditions. Some important factor used to determine the avalanche hazard include:

New snow or rain
Wind speed and direction
Existing snow conditions

This information is combined with a mountain weather forecast to predict the chance an avalanche will occur on a particular mountain slope.
