Danger level
Danger Level 3 - Considerable above the treeline
Danger Level 1 - Low above the treeline
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-SW-W-NW
Persistent weak layer above 2200m, S-SW-W


Wind slabs are to be evaluated critically. Weakly bonded old snow requires caution.

Fresh and somewhat older wind slabs must be evaluated with care and prudence in all aspects above the tree line, especially adjacent to ridgelines and in gullies and bowls. The number and size of avalanche prone locations will increase with altitude. Avalanches can additionally in isolated cases be released in the weakly bonded old snow on steep south, southwest and west facing slopes. In areas where the snow cover is rather shallow the avalanche prone locations are more prevalent.
Avalanches can as before be released, even by a single winter sport participant and reach medium size. Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger.

Snowpack

dp 6: cold, loose snow and wind
dp 4: cold following warm / warm following cold

Brittle wind slabs have formed in particular on northeast, east and southeast facing slopes. 10 to 15 cm of snow, and up to 20 cm in some localities, will fall. As a consequence of fresh snow and stormy weather the wind slabs will increase in size additionally. They are bonding poorly with the old snowpack in all aspects above the tree line.
Faceted weak layers exist in the top section of the old snowpack on steep sunny slopes.

Tendency

As a consequence of fresh snow and stormy weather there will be an increase in the avalanche danger.

Danger level
Danger Level 2 - Moderate above the treeline
Danger Level 1 - Low above the treeline
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-NW


Wind slabs are to be evaluated critically.

Fresh and somewhat older wind slabs must be evaluated with care and prudence in particular on northwest to east to south facing aspects above the tree line, especially adjacent to ridgelines and in gullies and bowls. The number and size of avalanche prone locations will increase with altitude.
Avalanches can as before be released, even by a single winter sport participant and reach medium size. Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger.

Snowpack

Brittle wind slabs have formed in particular on northwest, east and south facing slopes. In some localities up to 10 cm of snow. will fall. As a consequence of fresh snow and stormy weather the wind slabs will increase in size additionally. They are bonding poorly with the old snowpack above the tree line.

Tendency

As a consequence of the storm force wind there will be only a slight increase in the avalanche danger.
