Avalanche prone locations blanketed, hard to recognize
Nocturnal hours: Gray skies, first at high altitudes, later on also at low altitudes, snowfall will set in during the early morning hours, snowfall level dropping to 1500 m. Friday daytime: The peaks will be shrouded by and large, light snowfall, snowfall level at 1300 m, only minor amounts expected. At 2000 m: -2 degrees. Light S/E winds.
Avalanche prone locations blanketed, hard to recognize
Avalanches can trigger in near-surface layers and, in isolated cases, reach medium size. Danger zones occur in steep ridgeline terrain, in transitions from shallow to deep snow, e.g. at entries into gullies and bowls. Activities in backcountry demand experience in outlying terrain and the ability to assess avalanche dangers on-site, as well as a cautious route selection. Glide-snow avalanches can trigger below 2600 m at any time of day or night and reach large size. Caution urged below glide cracks. Due to rain immpact, only small-sized wet loose-snow avalanches can be expected.
The snowdrift layers from the beginning of the week have stabilized. On north-facing slopes at high altitudes the near-surface layers are still trigger-prone. The snowpack is mostly compact and stable, there is still powder on high-altitude shady slopes. Elsewhere the snowpack surface is moist and forms a melt-freeze crust at night which softens during the daytime. Up to 10 cm of fresh snow expected on Friday. Warm ground and the wet snowpack base reinforce the gliding movements of the entire snowpack.
On Saturday, sunny and windy weather. Avalanche danger levels are not expected to change significantly. Glide-snow and moist loose-snow avalanches are still possible.
