Weakly bonded old snow at high altitudes and in high Alpine regions. In addition the more recent wind slabs should be taken into account.
Avalanches can in very isolated cases be released in the old snowpack and reach medium size in particular on steep shady slopes. This applies in particular in case of a large load. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.
The spring-like weather conditions gave rise to increasing consolidation of the snowpack in particular at low and intermediate altitudes. It is largely stable and its surface has a melt-freeze crust that is strong in many cases, in particular on steep sunny slopes below approximately 2200 m. The high temperatures on Thursday gave rise to significant moistening of the snowpack on sunny slopes. In shady places that are protected from the wind intermediate and high altitudes: Towards its surface, the snowpack is fairly homogeneous; its surface consists of faceted crystals. Towards its base, the snowpack is faceted and weak. This applies in particular on steep east, north and northwest facing slopes,.
