Weakly bonded old snow in particular on steep shady slopes.
Weakly bonded old snow on steep shady slopes. Distinct weak layers in the upper part of the snowpack can be released in isolated cases even by individual winter sport participants on steep shady slopes. This applies in particular in little used terrain as well as in areas where the snow cover is rather shallow above approximately 2300 m. Avalanches can penetrate even deep layers and reach a dangerous size. Distinct weak layers in the old snowpack necessitate defensive route selection. Isolated whumpfing sounds can indicate the danger.
Snowpack
dp.6: cold, loose snow and wind dp.5: snowfall after a long period of cold
Over a wide area 50 cm of snow, and up to 70 cm in some localities, will fall until the early morning above approximately 1800 m. The new snow can be released easily or naturally in all aspects above the tree line. Snow profiles and stability tests have confirmed the distinct danger. The covering of new snow is soft. Distinct weak layers in the upper part of the snowpack are difficult to recognise. The new snow will be deposited on surface hoar in areas close to the tree line. Above the tree line: Towards its base, the snowpack is faceted and weak. Over a wide area new snow is lying on a weakly bonded old snowpack. Avalanches can be released in deeper layers very easily.
