Avalanche Activity

As a consequence of new snow and wind the prevalence and size of the avalanche prone locations will increase as the day progresses.

As a consequence of snowfall above approximately 800 m and the moderate to strong wind, fresh snow drift accumulations will form in the course of the day, in particular in gullies and bowls, and behind abrupt changes in the terrain. These conditions will cause a gradual rise in the avalanche danger as the day progresses. The fresh snow and in particular the wind slabs that are forming in particular at intermediate and high altitudes can be released by a single winter sport participant in some cases. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.

Snowpack Structure

5 to 20 cm of snow, and even more in some localities, will fall from midday. As a consequence of new snow and a light to moderate easterly wind, sometimes deep wind slabs will form in particular in gullies and bowls as well as at intermediate and high altitudes. At low altitude only a small amount of snow is lying for the time of year.
