Weather Forecast

On Tuesday, sunshine all day long above 1500-2000m. Further west, skies will be cloudless, although high-fog can form for several hours. A light easterly wind will be blowing. At 3000m: -14 degrees; at 2000m: from east to west -13 to -8 degrees; at 1000m: -4 to +1 degree. Source: GeoSphere Austria

Tendency

Fresh snowdrifts need to be cautiously assessed. Pay attention to weak layers in old snowpack.

Snowpack Structure

In the lowermost part of the snowpack there are faceted, expansively metamorphosed weak layers, esp. on W/N/E facing slopes. The fresh snowdrift accumulations lie deposited atop an unfavorable old snowpack surface in high-alpine zones. Highly varied snow depths, depending on wind impact.

Avalanche Activity

Caution: isolated weak layers prone to triggering. Heed drifts.

Weak layers in the old snow can be triggered in many cases by one sole skier on steep W/N/E facing slopes above 2200m. Caution in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls, releases can reach medium size. Due to northerly winds, trigger-sensitive snowdrift accumulations were generated in gullies, bowls and behind protruberances in the landscape. They can be triggered by one sole skier in the weak old snow, esp. on NW/N/E facing slopes above 2200m. Danger zones are generally small-sized and can be triggered in isolated cases, they increase in frequency with ascending altitude. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate consideration.
