Small-scale snowdrifts above the treeline still triggerable.
Avalanche danger is low. Older snowdrifts are the main problem. Small slab avalanches, at higher altitudes isolated medium-sized slab avalanches, can in particular be triggered by large additional loading. Avalanche prone locations are found in steep ridgeline terrain in N/E/SW aspects, and in gullies and bowls filled with wind-transported snow. Size and frequency of avalanche prone locations increase with ascending altitude. Possibility of small glide snow avalanches on smooth steep grass-covered slopes.
Some centimeters of loose snow are blanketing a wind-impacted melt-freeze encrusted old snowpack, and in places snowdrift accumulations. Embedded in the snowdrift accumulations are, in parts, trigger-sensitive boundary layers consisting of faceted crystals that were able to form while precipitation paused. In particular on south-facing slopes the layers are increasingly bonding. At higher altitudes and on shady slopes the snowpack base is very compact. At lower altitudes and on sunny slopes, a thin layer of powdry snow is found directly on the ground.
Due to solar radiation and calm weather the avalanche danger will slowly decrease further in the next few days.
