In sintesi

Weakly bonded old snow above approximately 2200 m. Fresh wind slabs require caution.

Problemi valanghivi

  • Persistent weak layers

    • Above 2,200 m
  • Wind slab

    • Above 2,200 m

Avalanche Activity

Weakly bonded old snow above approximately 2200 m. Fresh wind slabs require caution.

Single winter sport participants can release avalanches in some places. These can penetrate even deep layers and reach large size in isolated cases. 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 sunny slopes at elevated altitudes. The avalanche prone locations are difficult to recognise. Whumpfing sounds 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. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls and on steep shady slopes. Their prevalence will increase with altitude. Careful route selection is recommended.

Snowpack Structure

Over a wide area 5 to 10 cm of snow, and even more in some localities, 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.

Tendency

Wind slabs and weakly bonded old snow represent the main danger. Some snow will fall on Tuesday in some regions. The wind will be moderate to strong in some regions. The avalanche danger will persist.
