Avalanche Activity

Gliding avalanches and moist snow slides are possible in isolated cases as before. Fresh wind slabs at elevated altitudes.

On extremely steep grassy slopes more gliding avalanches are possible at any time, but they can reach medium size in isolated cases. Areas with glide cracks are to be avoided. In addition from midday very occasional small moist loose snow slides are possible. They can be released by people or triggered naturally. Shady slopes: The old snowpack will be generally stable. As a consequence of new snow and a sometimes strong wind from southwesterly directions, mostly shallow wind slabs formed on Monday in particular in the vicinity of peaks. In isolated cases they are only small but can be released also by a single winter sport participant. Apart from the danger of being buried, restraint should be exercised in view of the danger of avalanches sweeping people along and giving rise to falls.

Snowpack Structure

Up to 5 cm of snow, and even more in some localities, has fallen since Monday above approximately 2000 m. The southwesterly wind has transported only a little snow. Shady slopes and high altitudes: The snowpack consists of faceted crystals and its surface has a crust that is strong in many cases. Sunny slopes: The surface of the snowpack will freeze to form a strong crust and will soften during the day. Above the tree line there are 10 to 40 cm of snow, and even more in some localities. At high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind. At low altitude no snow is lying.

Tendency

Thursday: The danger of gliding avalanches and moist snow slides will persist. Further decrease in danger of dry avalanches.
