Avalanche Activity

Fresh snowdrifts. Considerable danger at high altitudes.

Above 1800 m danger is considerable, below that altitude danger is moderate. Danger zones: fresh snowdrift accumulations at high altitudes in E/S aspects, where one sole skier can trigger a slab avalanche. Poor visibility make evaluation more difficult on-site.

Snowpack Structure

Beneath the fresh snow from last weekend, weak layers have formed which, however, cannot easily be triggered. On Friday the snowpack was moistened by rainfall, on Saturday blanketed by fresh snow, which led to a destabilized snowpack and snowdrifts. At low altitudes the snowpack is melt-freeze encrusted, below that moist down to the ground.

Weather Synopsis

Palm Sunday will begin with sunshine in the rimline ranges, in the afternoon cloud cover will increase but tendency to showers will be low. Winds stormy from the northwest in the morning, then will slacken off. At 2000 m: -7 degrees.

Tendency

On Monday, hardly any wind, frequent sunshine. In the afternoon, a few clouds, most peaks will be free. Further west, more sunshine. Milder. At 2000 m: from -5 degrees in early morning to +2 degrees in the evening. The snowdrift problem will recede.
