The far-reaching snowdrifts are prone to triggering

Avalanche danger above 1800 m is considerable, below that altitude danger is moderate. The fresh snow and wide-ranging snowdrift accumulations are prone to triggering. A medium-sized avalanche can be triggered by 1 person. Danger zones occur in all aspects, increase with ascending altitude in both size and frequency. Backcountry tours require a cautious route selection. Particularly on steep smooth slopes in all aspects, medium-sized glide-snow avalanches are possible. Glide cracks are indicators of potential danger.

Persistent storm-strength W/NW winds massively transporting the snow, crests and ridges are bare of snow, utterly windblown, the surfaces show severe wind impact and are encrusted. More drifts are being generated by westerly winds, trigger-sensitive where soft layers were blanketed. Also, there are weak layers inside the fresh snow and drifts. At intermediate altitudes the snow base is moist or wet, furthering gliding snow masses over smooth ground.

Nocturnal hours: Heavy cloud in the early part of the night, later dispersing. Sunday daytime: Clouds will disperse by noon, later on light snowfall, snowfall level ascending to nearly 2000 m. At 2000 m: -2 to +3 degrees. Strong to stormy westerly winds.

The zero-degree level will ascend to nearly 3000 m on Monday, perhaps even higher, the snowpack will settle, avalanche danger will decrease. With higher temperatures, more glide-snow avalanches can be expected. On sunny slopes the solar radiation will cause loose-snow avalanches.
