Areas with glide cracks are to be avoided.The wind slabs must be evaluated with care and prudence in all aspects above the tree line. The fresh wind slabs are rather small but can be released easily. <br/> On very steep grassy slopes and on sunny slopes gliding avalanches are possible, in particular medium-sized ones. Exposed parts of transportation routes can be endangered in particular in the regions with a lot of snow. Areas with glide cracks are to be avoided. <br/> In very isolated cases avalanches can be triggered in deep layers of the snowpack and reach very large size. This applies in case of releases originating from very steep starting zones at high altitudes and in high Alpine regions that have retained the snow thus far, especially at transitions from a shallow to a deep snowpack. This applies in particular in case of a large load.As a consequence of the moderate to strong southwesterly wind, fresh snow drift accumulations formed on Friday, in particular on near-ridge shady slopes. In some cases the various wind slabs have bonded poorly together. This applies at high altitudes and in high Alpine regions. Towards its surface, the snowpack is soft and its surface consists of surface hoar, especially in areas close to the tree line. The fresh wind slabs will be deposited on surface hoar in some places. Faceted weak layers exist deep in the old snowpack in particular at high altitudes and in high Alpine regions. Towards its base, the snowpack is moist, in particular at low and intermediate altitudes.The weather conditions will foster a gradual change towards better conditions. Caution is to be exercised in areas with glide cracks.dangerRatingMapSimplified danger rating map of the regionhttps://avalanche.report/albina_files/2020-12-13/2020-12-13_07-00-00/9d6845c3-1a4b-4684-8582-9c9abc09f024.jpgwebsiteLink to region on the websitehttps://avalanche.report/bulletin/2020-12-13?region=9d6845c3-1a4b-4684-8582-9c9abc09f0242020-12-13T07:00:00Z2020-12-12T23:00:00Z2020-12-13T23:00:00ZPrealpsCembra ValleyBondone and StivoVallarsaWestern Nonsberg AlpsFolgaria - LaveroneLedro ValleyPaganellaMarzola - ValsuganaPine' - Mocheni Valleyconsiderabletreelineno_ratingno_ratingmoderatetreelineno_ratingno_ratingdp2wind_drifted_snowNWNWNEEtreelineconsiderableconsiderable333gliding_snowSNWNWNESEESWmoderatemoderate13decreasing2020-12-13T23:00:00Z2020-12-14T23:00:00ZMore gliding avalanches are possible.
