Danger level 3 (Considerable danger)
Danger level 4 (High danger)
Danger level 5 (Very high danger)
No danger level
Danger level 1 (No or minor danger)

Triggering is generally possible only from high additional loads in isolated areas of very steep, extreme terrain. Only sluffs and small-sized natural avalanches are possible.

Transportation routes and settlements:

No danger.

Outside secured zones:

Generally safe conditions.

Snowpack stability:

The snowpack is well bonded and stable in general.

Danger level 2 (Moderate danger)

Triggering is possible primarily from high additional loads, particularly on those steep slopes indicated in the bulletin. Large-sized natural avalanches are unlikely.

Transportation routes and settlements:

Low danger of natural avalanches.

Outside secured zones:

Mostly favourable conditions. Careful route selection, especially on steep slopes of indicated aspects and altitude zones.

Snowpack stability:

The snowpack is only moderately well bonded on some steep slopes, otherwise well bonded in general.

Danger level 3 (Considerable danger)

Triggering is possible, even from low additional loads particularly on those steep slopes indicated in the bulletin. In some cases medium-sized, in isolated cases large-sized natural avalanches are possible.

Transportation routes and settlements:

Isolated exposed sectors are endangered. Some safety measures recommended in those places.

Outside secured zones:

Partially unfavourable conditions. Experience in the assessment of avalanche danger is required. Steep slopes of indicated aspects and altitude zones should be avoided if possible.

Snowpack stability:

The snowpack is moderately to poorly bonded on many steep slopes.

Danger level 4 (High danger)

Triggering is likely even from low additional loads on many steep slopes. In some cases, numerous medium-sized and often large-sized natural avalanches can be expected.

Transportation routes and settlements:

Many exposed sectors are endangered. Safety measures recommended in those places.

Outside secured zones:

Unfavourable conditions. Extensive experience in the assessment of avalanche danger is required. Remain in moderately steep terrain / heed avalanche run out zones.  

Snowpack stability:

The snowpack is poorly bonded on most steep slopes.

Danger level 5 (Very high danger)

Many large and multiple very large natural avalanches are expected, even in moderately steep terrain.

Transportation routes and settlements:

Acute danger. Comprehensive safety measures.

Outside secured zones:

Highly unfavourable conditions. Avoid open terrain.  

Snowpack stability:

The snowpack is poorly bonded and largely unstable in general.
