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


Fresh wind slabs above the tree line.

As a consequence of the snowfall, the likelihood of dry avalanches being released will increase further especially above the tree line. Especially in places where the wind is storm force the avalanche danger is greater. The number and size of avalanche prone locations will increase as the day progresses. 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

Up to 10 cm of snow, and even more in some localities, will fall. This applies in particular in the regions neighbouring those that are subject to danger level 3 (considerable). The sometimes storm force wind will transport the fresh snow significantly. In particular adjacent to ridgelines and in gullies and bowls brittle wind slabs will form. This applies in particular above the tree line.

Tendency

The danger of slab avalanches will persist.

Danger level
Danger Level 1 - Low
Avalanche Problem
Wind-drifted snow above 2000m, N-NE-E-SE-S-SW-W-NW
Persistent weak layer above the treeline, N-NE-E-SE-S-NW


The sometimes strong wind will transport only a little snow.

Fresh and somewhat older 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. The early morning will see favourable conditions generally. In steep terrain there is a danger of falling on the icy crust.

Snowpack

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

Tendency

The wind will be moderate to strong at times in some localities.
