Upper Passeier Valley

Considerable avalanche danger will persist. Wind slabs and weakly bonded old snow represent the main danger.

Considerable avalanche danger will persist. Wind slabs and weakly bonded old snow represent the main danger.

The fresh and older wind slabs can be released easily, even by a single winter sport participant,. The avalanche prone locations are to be found in all aspects above the tree line. They are numerous and are barely recognisable because of the poor visibility. At elevated altitudes the avalanche prone locations are more prevalent. Mostly avalanches are medium-sized. Remotely triggered avalanches are possible in isolated cases. Additionally avalanches can also be released in deep layers. Such avalanche prone locations are to be found on steep, little used shady slopes above approximately 2200 m and on steep sunny slopes above approximately 2500 m. Especially transitions from a shallow to a deep snowpack are unfavourable. Backcountry touring and other off-piste activities call for caution and restraint.

In particular in the east and in the west 5 to 10 cm of snow will fall. The wind will be moderate to strong. Fresh wind slabs are lying on weak layers in all aspects above the tree line. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on sunny slopes above approximately 2500 m. The snowpack remains quite prone to triggering. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication.

Considerable avalanche danger will persist. The fresh wind slabs of the weekend are bonding only slowly with the old snowpack. The snowpack remains quite prone to triggering.
