Avalanche Activity

Fresh wind slabs represent the main danger.

Avalanches can in some places be released by a single winter sport participant and reach medium size. The avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain, especially on steep north and east facing slopes above the tree line, but in isolated cases also in areas close to the tree line. Avalanches can in isolated cases be released in the weakly bonded old snow in particular in shady places that are protected from the wind. Isolated whumpfing sounds and shooting cracks when stepping on the snowpack can indicate the danger.

Snowpack Structure

15 to 30 cm of snow, and up to 40 cm in some localities, has fallen since Sunday. The wind was strong at times. The fresh wind slabs are lying on soft layers. They are lying on surface hoar in some places. Faceted weak layers exist in the bottom section of the old snowpack in particular on west, north and east facing slopes.

Tendency

Over a wide area 5 to 10 cm of snow, and even more in some localities, will fall. The wind slabs of the last few days will be covered with new snow in some cases and therefore difficult to recognise.
