The older wind slabs are mostly shallow but to be assessed with care and prudence. The mostly shallow wind slabs represent the main danger. They are to be found in particular adjacent to ridgelines in all aspects and in the high Alpine regions. Avalanches can be released, in particular by large loads and reach medium size. The avalanche prone locations are to be found especially on steep shady slopes above approximately 2200 m, and adjacent to ridgelines and in gullies and bowls in all aspects. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. The wind has transported the fresh snow and, in some cases, old snow as well. Faceted weak layers exist deep in the snowpack in particular on north and east facing slopes. The snowpack remains subject to considerable local variations in particular on wind-loaded slopes. The backcountry touring conditions remain quite favourable. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-21/2018-12-20_16-00-00/e3f16c52-a785-45c1-8ba8-539cda388566.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-21?region=e3f16c52-a785-45c1-8ba8-539cda388566 2018-12-20T16:00:00Z 2018-12-20T23:00:00Z 2018-12-21T23:00:00Z Avalanche.report https://avalanche.report Brandenberg Alps Western Kitzbühel Alps moderate moderate 2 2 2 dp6 wind_drifted_snow NW E NE N treeline increasing 2018-12-21T23:00:00Z 2018-12-22T23:00:00Z Wind slabs represent the main danger. As a consequence of a strong wind from southwesterly directions, sometimes avalanche prone wind slabs will form as the day progresses in all aspects. Places where surface hoar has been covered with snow are especially unfavourable. Mostly avalanches are only small but can be released by a single winter sport participant. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls. They are barely recognisable because of the poor visibility. As a consequence of warming, the likelihood of moist snow slides being released will increase a little below the tree line. In the regions with a lot of snow gliding avalanches are possible below approximately 2200 m. The snowpack will be subject to considerable local variations. Soft weak layers exist in the top section of the snowpack. The fresh wind slabs will be deposited on surface hoar in particular on shady slopes. The wind slabs are mostly small but prone to triggering. No distinct weak layers exist deep in the snowpack. At low altitude from a snow sport perspective, in most cases insufficient snow is lying.

The fresh wind slabs can be released, even by a single winter sport participant and reach medium size. The number and size of avalanche prone locations will increase at high altitude and in the high Alpine regions. These avalanche prone locations are barely recognisable because of the poor visibility. Weak layers in the lower part of the snowpack can be released in some places by winter sport participants on steep west, north and east facing slopes, in particular between approximately 2200 and 2800 m. This applies especially in areas where the snow cover is rather shallow. Defensive route selection is recommended. Some snow will fall. The snowpack will be in some cases prone to triggering. The brittle wind slabs can be released easily. or in isolated cases naturally, in all aspects above the tree line. Shady slopes where surface hoar has been covered with snow are especially unfavourable. Faceted weak layers exist in the old snowpack on steep west, north and east facing slopes, in particular above approximately 2200 m and below approximately 2800 m. Isolated whumpfing sounds serve as an alarm indicating the danger. As a consequence of warming, the likelihood of moist loose snow avalanches being released will increase below the tree line.
