Rising wet-snow avalanche danger during course of day

During the course of the day, danger of wet-snow avalanches will increase. Isolated wet slab avalanches can be triggered by winter sports enthusiasts. After the melt-freeze crust (capable of bearing loads) softens up, also naturally triggered wet-snow avalanches are possible. Caution urged particularly towards steep shady slopes at 2200-2500m which have not yet discharged and slopes in all aspects where there is area-wide snow on the ground. Avalanches can fracture in weak old snowpack layers, in isolated cases grow to large size and lay back huge runout zones, quite atypically. On steep slopes with lots of snow on the ground which have not yet discharged with smooth underground, such as grass-covered slopes or rock plates, glide-snow avalanches can release in all aspects. In addition, winter sports enthusiasts can trigger isolated avalanches in near-surface weak layers on high-altitude shady slopes. Such danger zones are nearly impossible to recognize.

Snowpack Structure

During the night, a melt-freeze crust will form which is capable of bearing loads, then soften up during the daytime. At altitudes of 1800-2500m the ground-level layer of rotten snow is thoroughly wet even on north-facing slopes and is prone to triggering. On shady, steep high-altitude slopes there are unfavorable intermediate layers in the uppermost metre of the snowpack which can be triggering in some places. A deep mid-level section of compact layers blankets a fundament of buried hoar and faceted crystals.

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.
