Distinct weak layers in the old snowpack represent the main danger. Fresh wind slabs require caution.
Weak layers in the old snowpack can be released easily by individual winter sport participants. Caution is to be exercised in particular on steep west, north and east facing slopes above approximately 2000 m. The avalanche prone locations are difficult to recognise. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger. Remotely triggered avalanches are possible. Mostly avalanches are medium-sized. In addition the fresh wind slabs of the last few days in gullies and bowls, and behind abrupt changes in the terrain are prone to triggering in some cases still. The avalanche conditions are unfavourable.
In some regions 10 to 20 cm of snow, and even more in some localities, has fallen since Sunday. The wind was strong at times. The snowpack will be prone to triggering. Wind slabs are lying on surface hoar in some places. Faceted weak layers exist in the bottom section of the old snowpack. This applies in particular on west, north and east facing slopes above approximately 2000 m.
Increase in avalanche danger as a consequence of the new snow. The weather report and anticipated change in the avalanche danger are uncertain.
