Avalanche Activity

Wind impact: fresh drifts, ongoing glide-snow avalanches

Avalanche danger is predominantly moderate. Main problem: snowdrift accumulations. Danger zones occur in steep wind-loaded terrain and ridgelines and increase in size and frequency with ascending altitude. A medium-to-large slab avalanche can be triggered by 1 person. Activities in outlying terrain require experience in assessing the terrain and avalanche dangers. At all altitudes in steep terrain and on smooth grass-covered slopes in all aspects, glide-snow avalanches are possible which can reach medium size. Caution in zones below glide cracks.

Snowpack Structure

The large amounts of fresh fallen snow with little wind have been able to settle at lower altitudes and bond with the old snowpack. At higher altitudes the settling process takes longer, due to low temperatures. In places there are soft layers or older snowdrift accumulations which have been blanketed over, and the bonding inside the fresh snow and between fresh and older snow is poor. There is currently little data available to the Avalanche Warning Service about the snowpack in various regions.

Weather Forecast

Nocturnal hours: Light foehn wind, no longer as cold. In the latter part of the night, a bit of snowfall is possible. Tuesday: Heavy cloud cover, a few snow showers over the daytime hoursr (5-10 cm). Temperatures will drop. At 2000 m: -4 to -7 degrees. Moderate to strong SW winds, shifting to NW in the evening.

Tendency

The avalanche situation is not expected to change significantly.
