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 by a single winter sport participant in all aspects above the tree line. In particular in the regions exposed to heavier precipitation numerous medium-sized and, in isolated cases, large slab avalanches are to be expected as the snowfall becomes more intense. As a consequence of new snow and a sometimes storm force wind, sometimes large wind slabs will form in the course of the day in all aspects. The off-piste conditions are dangerous. Temporary safety measures may be necessary.

Gliding snow

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. Caution is to be exercised in areas with glide cracks. As a consequence of the rain, the likelihood of gliding avalanches being released will increase quickly in all aspects at low and intermediate altitudes. Numerous gliding avalanches are possible at any time, even large ones in isolated cases. Individual gliding avalanches can also be released in the night or in the morning. Exposed transportation routes and exposed settlements can be endangered. The gliding avalanches can in isolated cases reach fairly large size and in some places endanger transportation routes that are exposed.
