The avalanche danger is low. Nevertheless, fresh drift snow areas can be triggered as small slab avalanches by a single person. The avalanche prone locations are located in particular in the steep terrain adjacent to the ridgeline, crest or summit in the north-west, east to south aspects as well as in gullies and bowls. The risk of being swept away and falling continues to outweigh the risk of burial.
Some new fallen snow was deposited by strong winds from westerly directions in the leeward areas as wind slab on a soft layer of snow interspersed with graupel. Up to around 1400 metres, some rain on Friday has partially moistened the snow cover, snowpack there is forming a melt-freeze crust with renewed cooling. Weak layers for slab avalanches form soft snow layers (new fallen snow, faceted crystals) in the transition to the crusted old snowpack, the foundation of which is occasionally weakened by kinetic metamorphism. The snow depth varies greatly. Hardness, blown and drifting snow-laden areas alternate.
It will be largely free of precipitation during the night to Saturday. During the day, it will be mostly cloudy. Snowfall will occur at times, especially in the afternoon and evening. The wind will blow moderately to briskly from the west at high altitudes. It will cool down considerably at all altitudes. The temperature at 2000 metres will be between -10 and -6 degrees, at 1500 metres between -6 and -2 degrees. Strong to gale-force winds with gusts of around 100 km/h from the north-west.
With some snowfall and strong north-westerly winds, the avalanche danger increases slightly.
