Natural dry avalanches are possible. In the regions exposed to a lot of wind this applies. Field observations and stability tests confirm the complex avalanche situation at elevated altitudes. The danger exists primarily in alpine snow sports terrain. The avalanche prone locations are widespread. They are sometimes covered with new snow and are barely recognisable, even to the trained eye. They are currently prevalent immediately adjacent to the pistes as well. Avalanches can in many places be released, even by a single winter sport participant. Caution is to be exercised in all aspects in areas close to the tree line, as well as above the tree line. Remotely triggered avalanches are possible. Natural avalanches are possible as a consequence of the sometimes strong wind, especially on wind-loaded slopes above the tree line. In some cases avalanches are large. Gliding avalanches can also occur. This applies on steep grassy slopes below approximately 2400 m. Great caution and restraint are required. Over a wide area 30 to 50 cm of snow has fallen. The wind was strong to storm force over a wide area, in particular at elevated altitudes. The fresh and older wind slabs are lying on top of a weakly bonded old snowpack in all aspects at elevated altitudes. As a consequence of the strong wind the wind slabs will increase in size once again until Friday. Faceted weak layers exist in the centre of the snowpack, in particular on shady slopes in areas close to the tree line, as well as above the tree line, also on steep sunny slopes at elevated altitudes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate the unfavourable bonding of the snowpack. As a consequence of low temperatures and the strong wind, the snowpack can not consolidate. The snowpack remains prone to triggering. The conditions are critical for winter sport activities outside marked and open pistes. As a consequence of the strong northerly wind, the snow drift accumulations will increase in size. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2021-12-10/2021-12-09_16-00-00/5bc10e90-b409-44bc-bbf7-b1ff62d9174a.jpg website Link to region on the website https://avalanche.report/bulletin/2021-12-10?region=5bc10e90-b409-44bc-bbf7-b1ff62d9174a 2021-12-09T16:00:00.004378Z 2021-12-09T23:00:00Z 2021-12-10T23:00:00Z Avalanche.report https://avalanche.report Latemar Southern Adamello Primiero - Pale di S.

Avalanches can in some places be released, mostly by large loads and reach medium size. Caution is to be exercised on wind-loaded slopes in areas close to the tree line, as well as on wind-loaded slopes above the tree line. The avalanche prone locations are sometimes covered with new snow and are therefore barely recognisable, even to the trained eye. At elevated altitudes the avalanche prone locations are more prevalent and larger. Individual natural avalanches are possible as the day progresses, but they will be mostly small. This applies in particular on wind-loaded slopes. Over a wide area 20 cm of snow, and up to 40 cm in some localities, has fallen. The wind was moderate to strong in some localities in some regions, in particular at elevated altitudes. The fresh and older wind slabs are to be avoided in particular in very steep terrain. Faceted weak layers exist in the centre of the snowpack, in particular on shady slopes in areas close to the tree line, as well as above the tree line, also on steep sunny slopes at elevated altitudes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate the unfavourable bonding of the snowpack. As a consequence of low temperatures and the moderate wind, the snowpack can not consolidate. The snowpack remains in some cases prone to triggering. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2021-12-10/2021-12-09_16-00-00/de4ab6db-6b25-4e1f-9c31-554cafa28899.jpg website Link to region on the website https://avalanche.report/bulletin/2021-12-10?region=de4ab6db-6b25-4e1f-9c31-554cafa28899 2021-12-09T16:00:00Z 2021-12-09T23:00:00Z 2021-12-10T23:00:00Z Avalanche.report https://avalanche.report Brandenberg Alps Western Kitzbühel Alps Wilder Kaiser Mountains - Waidring Alps Eastern Kitzbühel Alps considerable treeline no_rating no_rating moderate treeline no_rating no_rating dp6 wind_drifted_snow SE SW S E NW W N NE treeline considerable considerable 2 3 3 wind_drifted_snow SE SW S E NW W N NE treeline moderate moderate 2 3 2 steady 2021-12-10T23:00:00Z 2021-12-11T23:00:00Z Fresh wind slabs are to be evaluated critically. The fresh and older wind slabs are prone to triggering in all aspects. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls, in particular in areas close to the tree line, as well as above the tree line. Such avalanche prone locations are widespread. They are sometimes covered with new snow and are therefore difficult to recognise. Avalanches can be released, even by a single winter sport participant and reach medium size. Dry avalanches can additionally in isolated cases be released in deeper layers. This applies in the south, especially on very steep shady slopes in areas close to the tree line, as well as above the tree line. Experience in the assessment of avalanche danger is required. Over a wide area 20 cm of snow, and even more in some localities, has fallen. The fresh wind slabs are lying on soft layers. As a consequence of the strong wind the wind slabs will increase in size once again. Isolated avalanche prone weak layers exist in the centre of the snowpack on shady slopes. This applies in the south, in particular at elevated altitudes. The wind slabs remain for the foreseeable future prone to triggering. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2021-12-10/2021-12-09_16-00-00/918b058c-04b1-4802-9c37-1c1ef72c806c.jpg website Link to region on the website https://avalanche.report/bulletin/2021-12-10?region=918b058c-04b1-4802-9c37-1c1ef72c806c 2021-12-09T16:00:00Z 2021-12-09T23:00:00Z 2021-12-10T23:00:00Z Avalanche.report https://avalanche.report Sexten Dolomites Val Müstair Alps Langtaufers Schnals Ridge Southern Stubai Alps Samnaun Mountains Southern Zillertal Alps and High Tauern Northern Oetz and Stubai Alps Saldurn-Mastaun Ridge Western Tuxer Alps Texel Mountains Eastern Tuxer Alps Sarntal Alps Western Pfunderer Mountains Glockturm Range Eastern Pfunderer Mountains Durreck Range Weißkugel Range Western Rieserferner Mountains Gurgler Range Western Deferegger Alps Central Stubai Alps Ortler Range Northern Zillertal Alps Ulten Valley Venediger Range Eastern Nonsberger Alps Mieming Mountains Eastern Rieserferner Mountains Northern Dolomites of Fiemme Karwendel Mountains Glockner Range Gröden Dolomites Eastern Deferegger Alps Prags Dolomites Schober Mountains Lienzer Dolomites Grieskogel Mountains considerable treeline no_rating no_rating moderate treeline no_rating no_rating dp6 dp5 wind_drifted_snow SE SW S E NW W N NE treeline considerable considerable 2 3 3 persistent_weak_layers SE SW S E NW W N NE treeline considerable considerable 3 4 2 gliding_snow SE SW S E W 2400 moderate moderate 1 2 steady 2021-12-10T23:00:00Z 2021-12-11T23:00:00Z Outside marked and open pistes a precarious avalanche situation will prevail.
