Fresh and somewhat older wind slabs must be evaluated with care and prudence in all aspects above approximately 2200 m. Avalanches can be released by a single winter sport participant and reach large size in isolated cases. The wind slabs are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. In isolated cases avalanches can be triggered in deep layers of the snowpack. The number and size of avalanche prone locations will increase with altitude. The current avalanche situation calls for careful route selection. In addition there is a danger of gliding avalanches. In some cases the wind slabs have bonded poorly with each other and the old snowpack. Wind slabs are clearly recognisable to the trained eye. Transitions from a shallow to a deep snowpack where weaknesses exist in the old snowpack are especially precarious. Faceted weak layers exist in the old snowpack, in particular on steep, rather lightly snow-covered east, south and west facing slopes as well as adjacent to ridgelines above approximately 2200 m. Slight decrease in danger of dry avalanches. 2019-12-30T16:00:00Z 2019-12-30T23:00:00Z 2019-12-31T23:00:00Z 3 2 drifting snow gliding snow The wind slabs represent the main danger. The fresh and somewhat older wind slabs are in many cases extensive and in some cases prone to triggering. Even single persons can release avalanches as before, in particular adjacent to ridgelines. Ski touring and other off-piste activities, including snowshoe hiking, call for experience in the assessment of avalanche danger and careful route selection, in particular on steep slopes above approximately 1800 m as well as on wind-loaded slopes. In steep terrain there is a danger of falling on the icy crust. Below approximately 2200 m small and, in isolated cases, medium-sized gliding avalanches are possible. The wind slabs have formed in particular in gullies and bowls, and behind abrupt changes in the terrain. These are in many cases extensive and in some cases prone to triggering. In some cases the various wind slabs have bonded still only poorly with each other and the old snowpack. The snowpack will be moist below approximately 2200 m. A latent danger of gliding avalanches exists, in particular at the base of rock walls below approximately 2200 m. 2019-12-30T16:00:00Z 2019-12-30T23:00:00Z 2019-12-31T23:00:00Z 2 drifting snow gliding snow 1800 2200 The fresh and somewhat older wind slabs must be evaluated with care and prudence in all aspects.

Ski touring and other off-piste activities, including snowshoe hiking, call for meticulous route selection, in particular on steep slopes above approximately 1800 m as well as on wind-loaded slopes. In steep terrain there is a danger of falling on the icy crust. Below approximately 2000 m mostly small gliding avalanches are possible. The wind slabs have formed in particular in gullies and bowls, and behind abrupt changes in the terrain. These are in many cases extensive and in some cases prone to triggering.

A certain danger of gliding avalanches and moist snow slides exists. This applies in particular on steep grassy slopes, especially on east, south and west facing slopes, but in isolated cases also on steep shady slopes below approximately 2000 m. Areas with glide cracks are to be avoided.

Restraint should be exercised because avalanches can sweep people along and give rise to falls. The avalanche prone locations are clearly recognisable to the trained eye. The various wind slabs have bonded generally well together. The snowpack will become increasingly stable. This also applies at high altitude. The snowpack will become increasingly moist, in particular on very steep sunny slopes. Currently there are quite favourable conditions generally.
