Weakly bonded old snow represents the main danger.
Avalanches can in isolated cases be released in the old snowpack and reach medium size. The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2200 m and on very steep sunny slopes above approximately 2400 m. They are barely recognisable, even to the trained eye. Isolated whumpfing sounds can indicate the danger. Backcountry touring and other off-piste activities call for a certain restraint. Small and medium-sized gliding avalanches are possible on steep grassy slopes, in particular in the regions with a lot of snow. Areas with glide cracks are to be avoided.
Faceted weak layers exist in the centre of the snowpack, especially on shady slopes above approximately 2200 m, as well as on sunny slopes above approximately 2400 m. The weather conditions will foster a gradual stabilisation of the snowpack.
Weak layers in the old snowpack necessitate caution. On steep grassy slopes small to medium-sized gliding avalanches are possible. Some snow will fall.
