Weakly bonded old snow and wet snow require caution.

Weakly bonded old snow and wet snow require caution.

Avalanches can be released in the old snowpack and reach large size in particular on west, north and east facing slopes. This applies even in case of a single winter sport participant. The avalanche prone locations are to be found especially on west, north and east facing slopes above approximately 2000 m and in all aspects at elevated altitudes. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack. Whumpfing sounds can indicate the danger. Remotely triggered avalanches are possible. In their paths avalanches can entrain the wet snow. This extends the avalanche runout distances. As the moisture increases small to medium-sized wet avalanches are to be expected. In the event of an overcast night this applies in particular. Caution is to be exercised in particular below approximately 2200 m. The runout zones are to be treated with caution.

On Sunday it will be mild over a wide area. Outgoing longwave radiation during the night will be reduced at times. Shady slopes: The snowpack remains prone to triggering in some places. Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. Sunny slopes: The surface of the snowpack will only just freeze and will already soften in the late morning. The weather conditions gave rise to thorough wetting of the snowpack below approximately 2200 m.

Weakly bonded old snow and wet snow are to be assessed with care and prudence.
