Adjacent to ridgelines in all aspects the wind slabs have increased in size once again in the last two days. They are to be avoided in particular in very steep terrain. The fresh wind slabs can as before be released by small loads or triggered naturally. This applies in particular adjacent to ridgelines as well as in gullies and bowls, and behind abrupt changes in the terrain. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. The surface of the snowpack is frozen, but not to a significant depth. Faceted weak layers exist in the bottom section of the snowpack in particular in shady places that are protected from the wind. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. The danger of natural avalanches will decrease gradually. 2019-02-12T16:00:00Z 2019-02-12T23:00:00Z 2019-02-13T23:00:00Z 3 2 DP6 DP2 drifting snow gliding snow Fresh wind slabs require caution.

Also places where surface hoar has been covered with snow are precarious. Caution is to be exercised in particular on steep shady slopes in areas close to the tree line as well as below the tree line. Dry avalanches can additionally in isolated cases be released in near-ground layers, in particular by large additional loads. Transitions from a shallow to a deep snowpack are unfavourable. In highly frequented off-piste terrain and on popular backcountry touring routes the avalanche situation is more favourable. A latent danger of gliding avalanches exists, in particular below approximately 2400 m on steep grassy slopes.

The large surface-area wind slabs of the last two days can be released easily in all aspects. Caution is to be exercised at their margins in particular. Avalanches can also release deeper layers of the snowpack and reach quite a large size. Weakly bonded old snow: Avalanches can in isolated cases be released by small loads, especially in areas where the snow cover is rather shallow. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. In highly frequented off-piste terrain and on popular backcountry touring routes the avalanche situation is more favourable. The avalanche danger will increase a little during the day. In the north 20 to 40 cm of snow. has fallen in the last three days. As a consequence of fresh snow and a strong to storm force northerly wind, easily released wind slabs formed in all aspects. The fresh wind slabs are lying on unfavourable layers. Faceted weak layers exist in the old snowpack in particular in areas where the snow cover is rather shallow.

The fresh wind slabs are lying on unfavourable layers in all aspects. They can be released even by a single winter sport participant. Faceted weak layers exist in the bottom section of the old snowpack especially on steep west, north and east facing slopes. This applies in shady places that are protected from the wind and at a distance from ridgelines. The avalanche prone locations are to be found in particular at transitions from a shallow to a deep snowpack and in areas close to the tree line. In highly frequented off-piste terrain and on popular backcountry touring routes the avalanche situation is a little more favourable. Backcountry touring and other off-piste activities call for caution. The strong wind has transported the fresh and old snow significantly. The fresh and older wind slabs are to be avoided as far as possible. Faceted weak layers exist in the bottom section of the snowpack in particular in shady places that are protected from the wind. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches during the day being released will increase gradually in particular on rocky sunny slopes.
