Weather Forecast

Once again, sunny weather in the mountains will prevail. With only a few cirrus clouds and daytime convective cloud build-up, very few limitations on visibility can be expected. Showers are not anticipated. Zero-degree level at 3000m. Temperature at 2000m: up to +8 degrees; at 3000m: 0 degrees. Mostly light westerly to northwesterly winds at high altitudes.

Tendency

Nocturnal outgoing longwave radiation will be limited. During the daytime on Sunday, temperatures will gradually drop, shower activity increase. The snowfall level will descend from 2200 down to 1800m. Danger of wet-snow avalanches will continue.

Avalanche Activity

Wet-snow danger in very steep terrain where there is still lots of snow

During the course of the day, danger of wet-snow avalanches will increase to moderate. Isolated wet slab avalanches can be triggered by winter sports enthusiasts. Avalanche prone locations occur generally only in summit zones. Avalanches will generally be medium-sized. On steep slopes where there is still lots of snow on smooth ground, glide-snow avalanches can trigger in all aspects.

Snowpack Structure

During the night, a melt-freeze crust will form which is capable of bearing loads, then soften up during the daytime. The snowpack is thoroughly wet up to summit zones in all aspects. Low altitude zones are bare of snow. On sunny slopes the ground is becoming bare of snow up to high altitudes.
