Weakly bonded old snow requires caution. As a consequence of a moderate to strong wind from westerly directions, clearly visible wind slabs formed in the last few days above the tree line. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in northwest to north to east facing aspects. Avalanches can in isolated cases be released by a single winter sport participant, but they will be small in most cases. In high Alpine regions and in the regions exposed to the foehn wind avalanche prone locations are a little more prevalent. Also places where surface hoar has been covered with snow are critical, in particular, west of the Sill. Weak layers in the lower part of the snowpack can be released in some places by winter sport participants on steep west, north and east facing slopes, in particular between approximately 2300 and 2800 m. This applies especially in areas where the snow cover is rather shallow. Careful route selection is advisable. The snowpack will be in some cases prone to triggering. The mostly small wind slabs of the last few days are lying on soft layers on northwest to north to east facing aspects. Places where surface hoar has been covered with snow are especially unfavourable. Faceted weak layers exist in the old snowpack on steep west, north and east facing slopes, in particular above approximately 2300 m and below approximately 2800 m. Isolated whumpfing sounds serve as an alarm indicating the danger. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-20/2018-12-19_16-00-00/c23cd1dc-9ebc-45bb-9b68-554690753d56.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-20?region=c23cd1dc-9ebc-45bb-9b68-554690753d56 2018-12-19T16:00:00Z 2018-12-19T23:00:00Z 2018-12-20T23:00:00Z Avalanche.report https://avalanche.report Southern Adamello Adamello - Presanella Northern Brenta - Peller Southern Brenta Sole, Pejo and Rabbi Maddalene Paganella moderate moderate 2 2 2 low 1 1 wind_drifted_snow NE W S N NW SW SE E 2200 persistent_weak_layers NE N NW E 2500 steady 2018-12-20T23:00:00Z 2018-12-21T23:00:00Z The danger exists in particular in alpine snow sports terrain.

Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. The wind has transported the fresh snow and, in some cases, old snow as well. Faceted weak layers exist deep in the snowpack in particular on north and east facing slopes.
