As a consequence of fresh snow and a strong to storm force wind from northwesterly directions, extensive wind slabs formed since Saturday. The wind slabs can be released very easily in all aspects above the tree line. Avalanches can in isolated cases reach large size. The danger exists in particular in alpine snow sports terrain. Backcountry touring and other off-piste activities call for extensive experience in the assessment of avalanche danger and great restraint. With the end of the intensive snowfall, the natural avalanche activity will appreciably decrease. Gliding avalanches are also to be expected, especially on steep grassy slopes. Over a wide area 30 to 60 cm of snow, and even more in some localities, has fallen in the last three days. The wind was strong to storm force. Over a wide area 20 to 40 cm of snow, and even more in some localities, will fall until the early morning. The wind slabs have bonded poorly together. The extensive wind slabs are covered with fresh snow in some cases and therefore difficult to recognise. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Gradual decrease in avalanche danger. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-11/2018-12-10_16-00-00/c771a688-cd2a-405e-b5d8-5c2ed6677141.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-11?region=c771a688-cd2a-405e-b5d8-5c2ed6677141 2018-12-10T16:00:00Z 2018-12-10T23:00:00Z 2018-12-11T23:00:00Z Avalanche.report https://avalanche.report Glockturm Range Weißkugel Range Gurgler Range Central Stubai Alps Northern Zillertal Alps Venediger Range high high 2 4 3 dp6 dp1 wind_drifted_snow E NW NE SW W N SE S treeline persistent_weak_layers NW NE N 2400 decreasing 2018-12-11T23:00:00Z 2018-12-12T23:00:00Z As a consequence of fresh snow and wind a high danger will be encountered in some regions. As a consequence of fresh snow and a strong to storm force wind from northwesterly directions, extensive wind slabs formed since Saturday. The wind slabs can be released very easily in all aspects above the tree line. Weak layers in the lower part of the snowpack can be released especially by large additional loads in particular on very steep shady slopes. This applies especially above approximately 2400 m. Avalanches can in isolated cases reach large size. The danger exists in particular in alpine snow sports terrain. Backcountry touring and other off-piste activities call for extensive experience in the assessment of avalanche danger and great restraint. With the end of the intensive snowfall, the natural avalanche activity will appreciably decrease. Gliding avalanches are also to be expected, especially on steep grassy slopes, in particular in the Zillertal Alps and in the Venediger Range. Over a wide area 30 to 60 cm of snow, and even more in some localities, has fallen in the last three days. The wind was strong to storm force. Over a wide area 30 to 50 cm of snow. will fall until the early morning. The wind slabs have bonded poorly with each other and the old snowpack. The extensive wind slabs are covered with fresh snow in some cases and therefore difficult to recognise.

This applies in all aspects above the tree line. As a consequence of fresh snow and wind the avalanche prone locations will become more prevalent. Dry avalanches can be released by a single winter sport participant. Backcountry touring calls for experience in the assessment of avalanche danger. Defensive route selection is advisable. Avalanche prone locations for gliding avalanches are to be found on steep grassy slopes below approximately 2400 m, especially in the Brandenberg Alps, in the Wilder Kaiser Mountains and in the Western Kitzbühel Alps.
