Weakly bonded old snow requires caution.

Weakly bonded old snow requires caution.

Winter sport participants can release avalanches in isolated cases. These can reach large size. The avalanche prone locations are to be found in particular on steep northwest, north and northeast facing slopes above approximately 2000 m and on steep west and east facing slopes above approximately 2200 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase a little on steep sunny slopes. Backcountry tours and off-piste skiing should be concluded timely.

Distinct weak layers exist in the bottom section of the snowpack on west, north and east facing slopes, in particular above approximately 2000 m. Towards its surface, the snowpack consists of faceted crystals, especially on shady slopes at elevated altitudes. Outgoing longwave radiation during the night will be good. The surface of the snowpack will freeze to form a strong crust. In steep terrain there is a danger of falling on the hard snow surface. The weather conditions as the day progresses will give rise to slight softening of the snowpack in particular on very steep sunny slopes.

Weakly bonded old snow requires caution. Slight increase in danger of wet avalanches as a consequence of warming during the day and solar radiation. After an overcast night this applies.
