Silvretta West — Bulletin d'avalanche

During the daytime hours, wet-snow avalanche danger will increase somewhat. One single winter sports enthusiast can trigger isolated wet-snow slab avalanches in very steep terrain below 2500m. Avalanches can fracture in the weak old snow and in isolated cases grow to large size. Whumpf noises and glide cracks in the old snow are indicators of danger. In addition, winter sports enthusiasts cn triggered avalanches in weak near-surface layers on high-altitude shady slopes. The danger spots are impossible to recognize. Caution urged towards small freshly generated snowdrift accumulations.

In the last few days there has been up to 10cm of fresh snow registered at high altitudes from local showers. Above 2500m the snowpack cools sufficiently during the night. The snowpack is thoroughly wet up to high altitudes, on north-facing slopes up to about 2500m. Lower altitudes are bare of snow. Sunny slopes are becoming bare of snow up to high altitudes. On shady high-altitude steep slopes there are unfavorable intermediate layers in the uppermost layer of the snowpack which in places can be triggered. A thick mid-level section of compact layers blankets a fundament of buried hoar and faceted crystals.
