European avalanche danger scale

© Saint-Martin-de-Belleville

The European avalanche danger scale indicates the winter hazard level in the mountains.

1/5 Low

The snow cover is stable on most slopes.

Avalanches are generally possible where there is highly excessive snow cover on isolated, very steep slopes. Only snowslides and small avalanches might happen naturally.

2/5 Moderate

On certain sufficiently steep slopes, the snow cover is only partially stabilised. It is stable in other areas.

Avalanches may be triggered, especially where snow cover is highly excessive and on certain slopes that are generally indicated. Large natural avalanches are unlikely.

3/5 Considerable

On many sufficiently steep slopes, the snow cover is barely or only partially stabilised.

Avalanches may be triggered, even where snow cover is only slightly excessive and in many areas, especially on certain slopes that are generally indicated. In certain situations some large, and in some cases very large natural avalanches are possible.

4/5 High

The snow cover is barely stabilised on most of the sufficiently steep slopes.

Triggering is likely, even where the snow cover is only slightly excessive, on many sufficiently steep slopes. In some cases, numerous large and often very large natural avalanches can be expected.

5/5 Very high

The snow cover is generally unstable.

Numerous very large natural avalanches can be expected, even in moderately steep terrain.
