Avalanche Activity

Predominantly favorable conditions in the morning. Beware slight daytime rise in danger.

Following good nocturnal outgoing longwave radiation the melt-freeze crust is capable of bearing loads in early morning, good conditions with low avalanche danger. Isolated triggerings are possible in extremely steep terrain by large additional loading. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. In high-altitude ridgeline terrain, fresh snowdrift accumulations require caution. Due to daytime warming and solar radiation, the snowpack forfeits its firmness and danger rises to Danger Level 2, moderate. Esp. on sun-basked steep slopes, small-to-medium wet-snow and glide-snow avalanches are possible. Backcountry tours should be launched early and brought to a close early in the day.

Snowpack Structure

The old snowpack is thoroughly wet up to high altitudes. Following good nocturnal outgoing longwave radiation the melt-freeze crust is capable of bearing loads in early morning hours. During the course of the day, it softens up from east-to-south-to-west, increasingly also on shady slopes, and thereby forfeits its firmness. In high-alpine regions, small-area snowdrift accumulations are evident. At lower altitudes there is little snow on the ground.

Weather Forecast

Serene and brilliantly sunny weather, zero-degree level at 3000m. Little wind. Outstanding visibility. At 2000m: +5 degrees. Light to moderate W/NW winds.

Tendency

Danger of dry-snow avalanches will recede only slowly. On Friday, much warmer, zero-degree level at 3000m. Danger of wet-snow and glide-snow avalanches will increase.
