Persistent weak layers
- Above 2,200 m
Weakly bonded old snow above approximately 2200 m. Fresh wind slabs require caution.
Over a wide area 5 to 10 cm of snow has fallen. The strong wind will transport the new snow and, in some cases, old snow as well. The fresh and older wind slabs are lying on the unfavourable surface of an old snowpack. Faceted weak layers exist in the old snowpack. This applies in all aspects above approximately 2200 m. The snowpack will be subject to considerable local variations.
Weakly bonded old snow above approximately 2200 m. Fresh wind slabs require caution.
Even single winter sport participants can release avalanches. These can penetrate even deep layers and reach medium size. The avalanche prone locations are to be found in all aspects. Caution is to be exercised in particular on very steep shady slopes above approximately 2200 m, as well as on very steep sunny slopes at elevated altitudes. The avalanche prone locations are difficult to recognise. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. Caution is to be exercised at transitions from a shallow to a deep snowpack. As a consequence of new snow and strong wind the wind slabs will increase in size once again. Their prevalence will increase with altitude. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls and on steep shady slopes. Meticulous route selection is advisable.
Some snow will fall on Tuesday over a wide area, in particular in the southeast. The wind will be moderate to strong in some regions. The avalanche danger will increase, in particular in the regions exposed to heavier precipitation.
