The avalanche prone locations are sometimes covered with new snow and are therefore difficult to recognise. In some cases the avalanches are medium-sized and can be released even by a single winter sport participant. 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. Over a wide area 10 cm of snow, and even more in some localities, will fall. The strong wind will transport the fresh and old snow. In some places wind slabs are lying on soft layers. <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/2020-12-25/2020-12-24_16-00-00/9e3c2aa0-bbf8-41ae-b92a-94e6a40c808c.jpg website Link to region on the website https://avalanche.report/bulletin/2020-12-25?region=9e3c2aa0-bbf8-41ae-b92a-94e6a40c808c 2020-12-24T16:00:00Z 2020-12-24T23:00:00Z 2020-12-25T23:00:00Z Avalanche.report https://avalanche.report Prealps Cembra Valley Bondone and Stivo Vallarsa Western Nonsberg Alps Eastern Nonsberger Alps Paganella Northern Dolomites of Fiemme moderate treeline no_rating no_rating low treeline no_rating no_rating dp6 wind_drifted_snow N SE S NW SW E W NE treeline moderate moderate 2 3 2 steady 2020-12-25T23:00:00Z 2020-12-26T23:00:00Z Wind slabs are to be evaluated with care and prudence.
