Significant increase in danger of dry avalanches as a consequence of new snow and strong wind. The fresh and somewhat older wind slabs can be released easily or naturally in all aspects. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. In some cases the avalanches are large. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Extensive experience in the assessment of avalanche danger is required. Over a wide area 15 to 30 cm of snow, and even more in some localities, will fall on Monday. As a consequence of a strong wind from southerly directions, avalanche prone wind slabs will form in all aspects. In many cases wind slabs are lying on soft layers, this also applies below the tree line. In its middle, the snowpack is well consolidated. Towards its base, the snowpack is faceted, especially on shady slopes above the tree line, as well as in all aspects in high Alpine regions. The avalanche danger will persist. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2020-12-28/2020-12-27_16-00-00/10ccd2f4-5f9e-44a9-bc12-fdfcb640734d.jpg website Link to region on the website https://avalanche.report/bulletin/2020-12-28?region=10ccd2f4-5f9e-44a9-bc12-fdfcb640734d 2020-12-27T16:00:00Z 2020-12-27T23:00:00Z 2020-12-28T23:00:00Z Avalanche.report https://avalanche.report Val Müstair Alps Western Verwall Mountains Langtaufers Eastern Verwall Mountains Allgäu Alps Silvretta Samnaun Mountains Eastern Lechtal Alps - Ammergau Alps Northern Oetz and Stubai Alps Mieming Mountains Western Tuxer Alps Karwendel Mountains Eastern Tuxer Alps Western Lechtal Alps Central Lechtal Alps Glockturm Range Grieskogel Mountains considerable treeline no_rating no_rating moderate treeline no_rating no_rating dp6 dp1 wind_drifted_snow N SE S NW SW E W NE treeline considerable considerable 2 3 3 new_snow N NW SE S SW E W NE moderate moderate 2 3 2 persistent_weak_layers N NW NE 2200 moderate moderate 3 3 1 steady 2020-12-28T23:00:00Z 2020-12-29T23:00:00Z Wind slabs are to be evaluated critically.

The fresh and somewhat older wind slabs can be released easily. or in isolated cases naturally, in all aspects, caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Mostly the avalanches are medium-sized. The number and size of avalanche prone locations will increase with altitude. <br/> Weak layers in the lower part of the snowpack can still be released in isolated cases by individual winter sport participants. Caution is to be exercised in particular on steep shady slopes above approximately 2200 m, especially in areas where the snow cover is rather shallow, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. 5 to 15 cm of snow, and even more in some localities, will fall on Monday. The strong wind will transport the fresh and old snow. In many cases wind slabs are lying on soft layers, also below the tree line. <br/> Steep shady slopes: The old snowpack will be prone to triggering in some places. Towards its base, the snowpack is faceted and weak. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication of a weakly bonded snowpack. The avalanche danger will persist. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2020-12-28/2020-12-27_16-00-00/8c74c365-6542-4524-bd60-5f210deced86.jpg website Link to region on the website https://avalanche.report/bulletin/2020-12-28?region=8c74c365-6542-4524-bd60-5f210deced86 2020-12-27T16:00:00Z 2020-12-27T23:00:00Z 2020-12-28T23:00:00Z Avalanche.report https://avalanche.report Brandenberg Alps Western Kitzbühel Alps Wilder Kaiser Mountains - Waidring Alps Eastern Kitzbühel Alps moderate treeline no_rating no_rating low treeline no_rating no_rating dp6 wind_drifted_snow N NW NE treeline moderate moderate 2 3 2 steady 2020-12-28T23:00:00Z 2020-12-29T23:00:00Z Wind slabs are to be evaluated with care and prudence.
