Weather Forecast

Winds will shift to westerly and temperatures will be quite mild, accompanied by intermittent sunshine. In the afternoon, skies will turn gloomy. In the evening, light snow showers will start, bringing only small amounts of snow. Snowfall level at 1600m. Temperature at 2000m: +1 degree, at 3000m: -7 degrees. High altitude winds: shifting to westerly, often blowing at brisk strength.

Tendency

On Sunday, avalanche danger could increase due to snowfall and strong-velocity winds from the west.

Avalanche Activity

Caution urged on steep, shady slopes. Fresh snowdrifts being generated during the daytime.

During the course of the day, mostly small-sized trigger-sensitive snowdrifts will accumulate. Older snowdrift masses can still be triggered, particularly on shady slopes. They have now been blanketed by fresh snowfall, making them difficult to recognize. Small-to-medium sized slab triggerings are possible by winter sports enthusiasts. In addition, slab avalanches can be unleashed in parts of the old snowpack by large additional loading. Caution urged on high-altitude very steep shady slopes. Naturally triggered glide-snow avalanches are still possible over smooth grass-covered ground and rock plates.

Snowpack Structure

Tonight some snowfall is anticipated. As a result of increasing westerly winds, the loosely-packed fresh snow will be transported during the course of the day, generating mostly small, trigger-sensitive snowdrift accumulations. Particularly in high-altitude ridgeline terrain, these will often be deposited on top of surface hoar. With ascending altitude, small-sized older snowdrifts are still prone to triggering. At high altitudes, especially on shady slopes, faceted intermediate layers occur inside the snowpack, and can be triggered in some places.
