The wind slabs are now only very rarely prone to triggering. Caution is to be exercised on steep shady slopes, as well as adjacent to ridgelines. <br/> Individual gliding avalanches are possible. Areas with glide cracks are to be avoided. The wind slabs are now only very rarely prone to triggering in all aspects. <br/> As a consequence of mild temperatures a crust formed on the surface during the last few days. This applies in particular on steep sunny slopes, as well as in all aspects at low and intermediate altitudes. Significant increase in avalanche danger as the precipitation becomes more intense. A lot of rain will fall on Wednesday in some regions. The danger of moist and wet avalanches will increase from midday. In the course of the day probably danger level 3 (considerable) will be reached. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2021-12-28/2021-12-27_16-00-00/63a55a6c-79dc-45f7-bda4-6ceb4b788bd3.jpg website Link to region on the website https://avalanche.report/bulletin/2021-12-28?region=63a55a6c-79dc-45f7-bda4-6ceb4b788bd3 2021-12-27T16:00:00.004096Z 2021-12-27T23:00:00Z 2021-12-28T23:00:00Z Avalanche.report https://avalanche.report Southern Adamello Primiero - Pale di S.

Weakly bonded old snow requires caution. Avalanches can in very isolated cases be released in the weakly bonded old snow by small loads, especially on very steep shady slopes above approximately 2200 m, as well as in gullies and bowls at elevated altitudes. In particular transitions from a shallow to a deep snowpack are unfavourable. The avalanche prone locations are rare but are barely recognisable, even to the trained eye. Faceted weak layers exist in the centre of the snowpack, in particular on shady slopes above approximately 2200 m. <br/> The snowpack will be generally subject to considerable local variations. Above the tree line snow depths vary greatly, depending on the infuence of the wind. The old snowpack consists of faceted crystals; its surface is loosely bonded and consists of surface hoar and faceted crystals. This applies in particular on shady slopes above the tree line. As a consequence of mild temperatures and solar radiation a crust formed on the surface. <br/> On sunny slopes below approximately 2000 m only a little snow is now lying. Up to 2000 m rain will fall on Wednesday in particular in the north. Slight increase in danger of wet and gliding avalanches as a consequence of the precipitation. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2021-12-28/2021-12-27_16-00-00/0fddcd39-b93e-4fa8-8e79-8fb206306360.jpg website Link to region on the website https://avalanche.report/bulletin/2021-12-28?region=0fddcd39-b93e-4fa8-8e79-8fb206306360 2021-12-27T16:00:00.004096Z 2021-12-27T23:00:00Z 2021-12-28T23:00:00Z Avalanche.report https://avalanche.report Sexten Dolomites Latemar Adamello - Presanella Northern Brenta - Peller Southern Brenta Allgäu Alps Eastern Lechtal Alps - Ammergau Alps Mieming Mountains Karwendel Mountains Western Lechtal Alps Central Lechtal Alps Grieskogel Mountains Val Müstair Alps Western Verwall Mountains Langtaufers Eastern Verwall Mountains Schnals Ridge Silvretta 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 Maddalene 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 Eastern Rieserferner Mountains Northern Dolomites of Fiemme Glockner Range Gröden Dolomites Eastern Deferegger Alps Prags Dolomites Schober Mountains Lienzer Dolomites Western Nonsberg Alps Fassa Valley Sole, Pejo and Rabbi low 2400 no_rating no_rating low 2400 no_rating no_rating dp7 persistent_weak_layers NE NW W N E 2400 low low 2 3 1 increasing 2021-12-28T23:00:00Z 2021-12-29T23:00:00Z A generally favourable avalanche situation will prevail.
