Danger level

treeline

Persistent weak layer

Treeline

Weak layers deep in the old snowpack represent the main danger.

Winter sport participants can release avalanches in isolated cases, with a large load in most cases. Avalanches can in very isolated cases penetrate deep layers and reach medium size. The avalanche prone locations for dry avalanches are to be found in particular on steep west, north and east facing slopes above the tree line.

Snowpack

dp.1: deep persistent weak layer

Above the tree line snow depths vary greatly, depending on the infuence of the wind. The snowpack will be subject to considerable local variations at elevated altitudes.
The somewhat older wind slabs of the last few days are lying on top of a weakly bonded old snowpack in particular on west to north to east facing aspects above the tree line. This also applies in isolated cases on south facing slopes in high Alpine regions.

In particular intermediate altitudes: As a consequence of mild temperatures and solar radiation a crust formed on the surface during the last few days.

Tendency

Weakly bonded old snow requires caution.

Persistent weak layer

Treeline

On shady slopes a moderate avalanche danger will be encountered in some localities.

Avalanches can in isolated cases be released by large loads, caution is to be exercised in particular in the regions with a lot of snow, and at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. The avalanche prone locations for dry avalanches are to be found in particular on steep northwest, north and northeast facing slopes above the tree line. Mostly avalanches are small.

Snowpack

The avalanche prone locations are to be found in particular on steep northwest to north to northeast facing slopes above approximately 1900 m.
As a consequence of mild temperatures and solar radiation a crust formed on the surface during the last few days.

Tendency

The avalanche prone locations are rather rare. At elevated altitudes a moderate avalanche danger will prevail.
