Considerable Avalanche Danger

Considerable is the third of five levels on the avalanche danger scale. Under considerable danger, natural avalanches are possible and human-triggered ones are likely. Avalanche conditions are considered dangerous and careful snowpack evaluation, cautious route-finding and conservative decision making is essential. Small avalanches can occur in many areas, large avalanches in specific areas, and very large avalanches in isolated areas.

Decision making under considerable danger can be challenging. While conditions are dangerous, avalanches may be less widespread, smaller, or less likely than under high avalanche danger, potentially making the danger less obvious. Many slopes should be avoided when avalanche danger is rated considerable. Use the Avaluator Trip Planner and Slope Evaluation Tools to help decide on appropriate areas to travel. 

Historically, the highest number of avalanche fatalities have occurred when the danger was rated considerable.
