The avalanche danger rating scale can be pretty confusing for a layman. Avalanche danger rating 3 on a scale of 5 doesn't sound too dangerous right? It's right in the middle! So you might think that there isn't much of a risk when skiing off-piste. Let's get straight to the point: avalanche danger rating 3 (Moderate) can be dangerous. About 20% of the snow cover has weak spots and spontaneous avalanches of medium size are possible. The weight of a single skier or snowboarder on the snow cover is enough to trigger an avalanche. Ergo: it definitely can be dangerous. How come?

The avalanche danger scale has two objectives. One objective is to express the risk that a catastrophic avalanche will threat public life (roads, bridges, villages) and the other objective is the probability of an avalanche in the ski areas, that threat skiers and snowboarders.
