In the last two days in all aspects a large number of medium-sized and, in many cases, large avalanches occurred naturally, in particular avalanches with origins in high-altitude starting zones. Once the intensive precipitation has ended, the natural avalanche activity will appreciably decrease. Single winter sport participants can release avalanches easily, including dangerously large ones, especially above approximately 2200 m. The sometimes large wind slabs of the last three days represent the main danger. These must be evaluated with care and prudence in all aspects above approximately 2200 m. The number and size of avalanche prone locations will increase with altitude. Dry avalanches can additionally be released in the old snowpack by a single winter sport participant, in particular in areas where the snow cover is rather shallow above approximately 2200 m and on very steep slopes. Decrease in danger of moist and wet avalanches. Caution is to be exercised in areas with glide cracks. This applies in particular on steep grassy slopes below approximately 2400 m. Snow sport activities outside marked and open pistes call for extensive experience in the assessment of avalanche danger and great restraint. Over a wide area 30 to 70 cm of snow, and up to 100 cm in some localities, fell above approximately 2000 m. The wind was strong to storm force. The fresh wind slabs are in many cases thick. Much of the fresh and wind-drifted snow of the last few days are bonding only slowly with the old snowpack in all aspects, in particular above approximately 2200 m. Avalanche prone weak layers exist in the centre of the snowpack. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-25/2018-12-24_16-00-00/3a9c1c3c-fa34-4b75-b712-395d5961420d.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-25?region=3a9c1c3c-fa34-4b75-b712-395d5961420d 2018-12-24T16:00:00Z 2018-12-24T23:00:00Z 2018-12-25T23:00:00Z Avalanche.report https://avalanche.report Glockner Range Eastern Deferegger Alps Schober Mountains Eastern Rieserferner Mountains Western Rieserferner Mountains Western Deferegger Alps considerable considerable 2 3 3 low 1 1 dp6 dp4 wind_drifted_snow SE E S NW NE W SW N 2200 persistent_weak_layers E NW NE W N 2200 2000 decreasing 2018-12-25T23:00:00Z 2018-12-26T23:00:00Z Fresh wind slabs represent the main danger.

Faceted weak layers exist in the centre of the snowpack in particular on west, north and east facing slopes. Isolated whumpfing sounds can indicate the danger. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-25/2018-12-24_16-00-00/e94773aa-d30e-40dd-94b7-8d2cedb9c4be.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-25?region=e94773aa-d30e-40dd-94b7-8d2cedb9c4be 2018-12-24T16:00:00Z 2018-12-24T23:00:00Z 2018-12-25T23:00:00Z Avalanche.report https://avalanche.report Western Tuxer Alps Eastern Tuxer Alps Brandenberg Alps Western Kitzbühel Alps Wilder Kaiser Mountains - Waidring Alps Eastern Kitzbühel Alps considerable considerable 2 3 3 low 1 1 dp6 wind_drifted_snow E NW NE W N 2200 decreasing 2018-12-25T23:00:00Z 2018-12-26T23:00:00Z Fresh wind slabs represent the main danger.

As a consequence of fresh snow and a strong wind from northwesterly directions, wind slabs formed on Monday in particular adjacent to ridgelines and in gullies and bowls. In particular on wind-loaded slopes avalanches can be released easily and reach large size in isolated cases. In regions neighbouring those that are subject to danger level 3 (considerable) and at high altitudes and in high Alpine regions avalanche prone locations are more prevalent and the danger is greater. The avalanche prone locations are clearly recognisable to the trained eye. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. Some snow has fallen in particular in the north. The snowpack will be subject to considerable local variations. In many cases fresh snow and wind slabs are lying on the soft surface of an old snowpack. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication of a weakly bonded snowpack. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-25/2018-12-24_16-00-00/4e43bb70-3d58-46eb-84ec-b3a3f390fde1.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-25?region=4e43bb70-3d58-46eb-84ec-b3a3f390fde1 2018-12-24T16:00:00Z 2018-12-24T23:00:00Z 2018-12-25T23:00:00Z Avalanche.report https://avalanche.report Eastern Nonsberger Alps Northern Dolomites of Fiemme Prealps Cembra Valley Bondone and Stivo Vallarsa Western Nonsberg Alps Folgaria - Laverone Ledro Valley Marzola - Valsugana Pine' - Mocheni Valley low low 1 3 1 wind_drifted_snow E NW NE N 2200 steady 2018-12-25T23:00:00Z 2018-12-26T23:00:00Z Little snow has fallen.
