The avalanches can occur easily or triggered naturally. As a consequence of fresh snow and a strong to storm force wind from southerly directions, easily released wind slabs formed in all aspects. Significant increase in avalanche danger in particular adjacent to ridgelines and in gullies and bowls. Fresh snow and wind slabs can be released, even by a single winter sport participant. Especially from starting zones at higher altitudes medium-sized and, in isolated cases, large natural avalanches are possible. Below approximately 2200 m medium-sized and, in isolated cases, large gliding avalanches are possible. In some localities 10 to 30 cm of snow. has fallen thus far above approximately 1800 m. In many cases fresh snow and wind slabs are lying on a moist old snowpack. 20 to 40 cm of snow, and even more in some localities, will fall in the next few hours above approximately 1600 m. The wind will be strong to storm force in the vicinity of peaks. During the night the wind slabs will increase in size once again. The conditions are unfavourable for ski touring, freeriding and snowshoe hiking. Fresh snow and wind slabs require caution. In the regions where more snow falls the avalanche danger is greater. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files_local/2019-12-21/2019-12-20_16-00-00/6ef694d7-0043-447b-9288-94b82da3d3c5.jpg website Link to region on the website https://avalanche.report/bulletin/2019-12-21?region=6ef694d7-0043-447b-9288-94b82da3d3c5 2019-12-20T16:00:00Z 2019-12-20T23:00:00Z 2019-12-21T23:00:00Z Avalanche.report https://avalanche.report Sexten Dolomites Eastern Pfunderer Mountains Durreck Range Val Müstair Alps Western Rieserferner Mountains Langtaufers Western Deferegger Alps Schnals Ridge Ortler Range Southern Stubai Alps Ulten Valley Southern Zillertal Alps and High Tauern Eastern Nonsberger Alps Saldurn-Mastaun Ridge Northern Dolomites of Fiemme Texel Mountains Gröden Dolomites Sarntal Alps Prags Dolomites Western Pfunderer Mountains considerable considerable 3 3 3 considerable 2 3 gliding_snow W N SE SW E NE S NW 2400 new_snow W N SE SW E NE S NW steady 2019-12-21T23:00:00Z 2019-12-22T23:00:00Z The snow sport conditions outside marked and open pistes are dangerous. As the precipitation becomes more intense dry and wet avalanches are possible during the night, in particular medium-sized ones, in the regions exposed to heavier precipitation in particular on wind-loaded slopes and. Especially below approximately 2400 m small and medium-sized gliding avalanches are to be expected. From high-altitude starting zones in the regions exposed to precipitation the avalanches can in isolated cases reach fairly large size and in some places endanger transportation routes that are exposed. Single winter sport participants can release avalanches very easily. Ski touring and other off-piste activities, including snowshoe hiking, call for extensive experience in the assessment of avalanche danger and careful route selection. As a consequence of fresh snow and a strong to storm force southwesterly wind, extensive wind slabs formed in the last few days also in areas not adjacent to ridgelines. 20 to 40 cm of snow, and up to 50 cm in some localities, will fall in the next few hours above approximately 1700 m. By the middle of the day the wind slabs will increase in size additionally. Faceted weak layers exist in the old snowpack in particular adjacent to ridgelines. The old snowpack will be moist below approximately 2200 m. Once the snowfall has ended, the natural avalanche activity will appreciably decrease. There is a danger of gliding avalanches, especially in the regions with a lot of snow in particular below approximately 2200 m. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files_local/2019-12-21/2019-12-21_05-45-20/76815572-e064-4056-8394-c95a48caed0c.jpg website Link to region on the website https://avalanche.report/bulletin/2019-12-21?region=76815572-e064-4056-8394-c95a48caed0c 2019-12-21T05:45:20Z 2019-12-20T23:00:00Z 2019-12-21T23:00:00Z Avalanche.report https://avalanche.report Western Tuxer Alps Eastern Tuxer Alps Western Lechtal Alps Central Lechtal Alps Grieskogel Mountains Western Verwall Mountains Eastern Verwall Mountains Allgäu Alps Silvretta Samnaun Mountains Eastern Lechtal Alps - Ammergau Alps Northern Oetz and Stubai Alps considerable treeline considerable 3 3 2 moderate 1 2 moderate treeline moderate 2 2 2 moderate 1 2 dp2 dp6 gliding_snow SE SW W E S 2600 wind_drifted_snow N NE NW treeline increasing 2019-12-21T23:00:00Z 2019-12-22T23:00:00Z Fresh wind slabs at high altitude.

Caution is to be exercised in areas with glide cracks. The fresh wind slabs will become increasingly prone to triggering in particular on steep shady slopes above approximately 2400 m. The snowpack will be subject to considerable local variations at high altitudes and in high Alpine regions.
