Treeline
Persistent weak layer


As a consequence of the strong to storm force northwesterly wind the size of the avalanche prone locations will increase.

The fresh snow of the last few days and the sometimes large wind slabs to be found in all aspects can be released easily or naturally in all aspects. Caution is to be exercised in case of releases originating from, high-altitude starting zones that have retained the snow thus far, especially in the regions neighbouring those that are subject to danger level 4 (high). Avalanches can also be released in the old snowpack and reach quite a large size. Remotely triggered avalanches are possible. Below the tree line the avalanche situation is more favourable. As a consequence of new snow and wind individual natural avalanches are possible.
In the regions with a lot of snow gliding avalanches are possible, even quite large ones. This applies in particular at low and intermediate altitudes.
The conditions are precarious for snow sport activities. Caution and restraint are recommended.

Snowpack

dp.6: cold, loose snow and wind
dp.2: gliding snow

In particular in the regions neighbouring those that are subject to danger level 4 (high) 10 to 20 cm of snow will fall from early morning. The strong wind will transport the fresh and old snow. The various wind slabs have bonded insufficiently together. In some places new snow and wind slabs are lying on soft layers.
In its middle, the snowpack is weak. Towards its base, the snowpack is largely stable. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.

Tendency

A precarious avalanche situation will persist in some cases. Temporary increase in danger of dry and moist avalanches as a consequence of warming, in particular below approximately 2400 m.

Wind slabs require caution.

The fresh wind slabs represent the main danger. The fresh snow of the weekend and the sometimes deep wind slabs can be released easily in all aspects and generally above the tree line. Natural avalanches are possible in isolated cases. Remotely triggered avalanches are possible.
In the regions with a lot of snow gliding avalanches are possible, even quite large ones. This applies in particular at low and intermediate altitudes.
The conditions are precarious for snow sport activities. Caution and restraint are recommended. As a consequence of warming individual natural avalanches are possible towards the evening.

Snowpack

dp.6: cold, loose snow and wind
dp.2: gliding snow

The strong wind has transported the new snow. In some places new snow and wind slabs are lying on soft layers.
In its middle, the snowpack is unfavourably layered. Towards its base, the snowpack is largely stable.

Tendency

In particular in the north some new snow. On Thursday the wind slabs will increase in size additionally.
