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-SW-W-NW


Wind slabs require caution.

The mostly shallow wind slabs of the last three days can be released easily above the tree line. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in all aspects. They will increase with altitude. In the regions neighbouring those that are subject to danger level 3 (considerable) the avalanche danger is higher.

Snowpack

dp 6: cold, loose snow and wind

The sometimes storm force wind has transported the fresh and old snow significantly. In particular adjacent to ridgelines and in gullies and bowls brittle wind slabs formed. This applies in particular above the tree line.

Tendency

The danger of dry slab avalanches will decrease gradually.

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


Wind slabs and weakly bonded old snow require caution.

More recent wind slabs are mostly rather small and can be released by large loads in particular. At high altitudes and in high Alpine regions avalanche prone locations are a little more prevalent. A clear night will be followed in the early morning by favourable conditions generally. In steep terrain there is a danger of falling on the icy crust.

Snowpack

dp 7: snow-poor zones in snow-rich surrounding

The snowpack will be in most cases well bonded. Adjacent to ridgelines and in gullies and bowls mostly small wind slabs formed. Avalanche prone weak layers exist in the old snowpack in particular on very steep grassy slopes.

Tendency

At transitions from a shallow to a deep snowpack and on wind-loaded slopes the avalanche situation is rather unfavourable.
