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


Fresh wind slabs require caution.

The fresh wind slabs can be released by a single winter sport participant in some cases in particular on steep shady slopes. They can be released in the weakly bonded old snow in particular in areas where the snow cover is rather shallow. In particular transitions from a shallow to a deep snowpack where weaknesses exist in the old snowpack are precarious. These places are clearly recognisable to the trained eye.

Snowpack

dp 5: snowfall after a long period of cold
dp 6: cold, loose snow and wind

5 to 10 cm of snow, but less in some localities, fell. The strong wind has transported the fresh snow and, in some cases, old snow as well. Especially above the tree line sometimes easily released wind slabs formed. The fresh snow and wind slabs of the last two days are lying on the unfavourable surface of an old snowpack in particular on shady slopes. Faceted weak layers exist in the old snowpack in particular here. At high altitudes and in high Alpine regions the avalanche prone locations are more prevalent.

Tendency

As a consequence of warming during the day and solar radiation dry and moist avalanches are possible.

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


Fresh wind slabs are to be evaluated with care and prudence.

In these regions the wind slabs have increased in size hardly at all. Mostly avalanches are only small but in some cases easily released. At high altitudes and in high Alpine regions avalanche prone locations are a little more prevalent. Adjacent to ridgelines avalanches can be triggered in deep layers of the snowpack and reach medium size in some cases. Restraint should be exercised because avalanches can sweep people along and give rise to falls. In steep terrain there is a danger of falling on the hard snow surface.

Snowpack

dp 6: cold, loose snow and wind

Up to 5 cm of snow, but less in some localities, fell above approximately 1200 m. The strong wind has transported the fresh and old snow. Especially above the tree line mostly small wind slabs formed. The fresh snow and wind slabs are lying on top of a weakly bonded old snowpack in particular on shady slopes. Faceted weak layers exist in the old snowpack in particular here.

Tendency

Wind slabs require caution.

Fresh wind slabs are to be evaluated with care and prudence.

In these regions the wind slabs have increased in size hardly at all. Mostly avalanches are only small but in some cases easily released. At high altitudes and in high Alpine regions avalanche prone locations are a little more prevalent. Adjacent to ridgelines avalanches can be triggered in deep layers of the snowpack and reach medium size in isolated cases. Restraint should be exercised because avalanches can sweep people along and give rise to falls. In steep terrain there is a danger of falling on the hard snow surface.

Snowpack

dp 6: cold, loose snow and wind

Over a wide area up to 5 cm of snow, but less in some localities, fell above approximately 1200 m. The strong wind has transported only a little snow. In particular adjacent to ridgelines and in pass areas mostly small wind slabs formed. The fresh snow and wind slabs are lying on top of a weakly bonded old snowpack in particular on shady slopes. Faceted weak layers exist in the old snowpack especially here.

Tendency

The conditions are mostly favourable for snow sport activities outside marked and open pistes. Wind slabs require caution.
