Weakly bonded old snow is to be evaluated with care and prudence.

Weakly bonded old snow is to be evaluated with care and prudence.

In some places avalanches can be triggered in the weakly bonded old snow and reach medium size in isolated cases. The avalanche prone locations are to be found in particular on steep west to north to east facing slopes above approximately 2400 m and on steep sunny slopes above approximately 2600 m. Caution is to be exercised at transitions from a shallow to a deep snowpack. The prevalence of the avalanche prone locations will increase with altitude. The fresh wind slabs are mostly small but can be released in isolated cases. Caution is to be exercised in particular on steep shady slopes at elevated altitudes. There is a danger of falling on the hard snow surface.

Towards its base, the snowpack is faceted, especially on steep west, north and east facing slopes above approximately 2400 m, as well as on steep sunny slopes at elevated altitudes. The northwesterly wind will transport the loosely bonded old snow. The fresh wind slabs are lying on soft layers in particular on shady slopes. Towards its surface, the snowpack is hard and its surface has a melt-freeze crust. This applies in particular on steep sunny slopes.

On Friday it will be very mild. The wind will be moderate to strong. The old snowpack remains prone to triggering in some places.
