Caution: glide-snow and wet-snow avalanches, fresh drifts at high altitudes
Avalanche danger is considerable. Where there is rain impact in steep terrain, forest lanes and on smooth grassy slopes in all aspects, increasing wet-snow avalanches, and continuing glide-snow avalanches are possible, which can reach large size. Beware zones below glide cracks. At high altitudes, fresh snowdrifts threaten, risky in wind-loaded steep terrain and in ridgeline terrain in all aspects. Small-to-medium slab avalanches can be triggered by 1 person, esp. in transitions from shallow to deeper snow, e.g. at entries into gullies and bowls.
The snowpack has been able to settle and stabilize. Due to rain impact, the snowpack is being weakened. Up to intermediate altitudes the lower part is moist, often on warm ground, favouring gliding snow masses. Due to strong-to-stormy winds, fresh snow will be transported and new drifts accumulate. Where they lie atop soft layers they are prone to triggering. There is currently little data available to the Avalanche Warning Service about the snowpack in various regions.
Nocturnal hours: Due to strong-to-stormy westerly winds, heavy rainfall will arise, the snowfall level ascend temporarily to 2000 m, in early morning at 1400 m. Sunday: Snow showers will decrease. The afternoon will be dry, with sunny phases. Temperature at 2000 m: -3 degrees. Brisk to strong westerly to northwesterly winds.
It will remain variable, with strong westerly winds. Snowfall only between 1700 and 2200 m. At higher altitudes the snowdrifts will increase the danger. Where there is rain impact, wet-snow and glide-snow avalanches can still be expected.
