Avalanche Activity

Slightly rising danger above the timberline due to snowdrifts

Fresh snowdrift accumulations in ridgeline terrain and behind protruberances in the landscape can easily be disturbed. Other isolated danger zones are located in extremely steep, predominantly shady terrain. In isolated cases, small avalanches can be triggered in these places in the old snow. Such danger zones are located particularly in transitions from shallow to deep snow, for example, at entry points into gullies and bowls. Apart from the risks of being buried in snow masses, the danger of being swept along and forced to take a fall also require caution.

Snowpack Structure

The most recent fresh snow and small-to-medium sized fresh snowdrift accumulations have been deposited on top of a generally well consolidated, predominantly melt-freeze encrusted old snowpack surface. In some places, surface hoar was blanketed by it. Particularly on steep shady slopes, weak layers in the old snow still persist in places. Overall there is little snow on the ground.

Weather Forecast

On Wednesday, southerly foehn winds will generate dispersed clouds and some sunshine. During the course of the day, air masses will become moist, clouds dense. In late afternoon, light snowfall is expected in many places. At 2000m: dropping from +1 to -4 degrees; at 3000m: from -5 to -8 degrees. Initially brisk southerly winds at high altitudes, later slackening off to moderate velocity.

Tendency

Avalanche danger will increase on Thursday due to fresh snow and winds
