The sometimes avalanche-prone wind slabs of the last few days represent the main danger. They are to be found in particular adjacent to ridgelines in all aspects and in the high Alpine regions. Wind slabs can be released, in particular by large loads and reach medium size. These avalanche prone locations are to be found in particular on steep slopes above approximately 2200 m, and adjacent to ridgelines and in gullies and bowls in all aspects. Backcountry touring and other off-piste activities call for experience in the assessment of avalanche danger and careful route selection. Also in the regions of the north that are exposed to the foehn wind a little fresh snow. The wind has transported the fresh snow and, in some cases, old snow as well. The snowpack remains prone to triggering especially on wind-loaded slopes. The avalanche conditions remain mostly favourable. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-17/2018-12-16_16-03-49/608f2163-7354-4458-b4fe-a3557c76de1c.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-17?region=608f2163-7354-4458-b4fe-a3557c76de1c 2018-12-16T16:03:49Z 2018-12-16T23:00:00Z 2018-12-17T23:00:00Z Avalanche.report https://avalanche.report Western Tuxer Alps Glockner Range Eastern Tuxer Alps Glockturm Range Grieskogel Mountains Weißkugel Range Gurgler Range Central Stubai Alps Northern Zillertal Alps Venediger Range Northern Oetz and Stubai Alps Eastern Rieserferner Mountains moderate moderate 2 3 2 dp6 dp1 wind_drifted_snow N NW NE E SE treeline persistent_weak_layers N W NW NE E 2300 2800 steady 2018-12-17T23:00:00Z 2018-12-18T23:00:00Z Fresh wind slabs represent the main danger.

The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in northwest to north to southeast facing aspects. At high altitudes and in high Alpine regions and in the regions exposed to the foehn wind avalanche prone locations are more prevalent. Also places where surface hoar has been covered with snow are critical, in particular in areas close to the tree line,, also below the tree line, in particular, west of the Sill. Weak layers in the old 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. The snowpack will be in some cases prone to triggering. Soft weak layers exist in the top section of the snowpack. The fresh snow of Sunday is lying on surface hoar in some places in areas close to the tree line. 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 indicate the danger. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-17/2018-12-16_16-03-49/b905689c-a697-43ba-acea-cc63b32c206f.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-17?region=b905689c-a697-43ba-acea-cc63b32c206f 2018-12-16T16:03:49Z 2018-12-16T23:00:00Z 2018-12-17T23:00:00Z Avalanche.report https://avalanche.report Karwendel Mountains Wilder Kaiser Mountains - Waidring Alps Western Lechtal Alps Central Lechtal Alps Western Verwall Mountains Eastern Verwall Mountains Allgäu Alps Silvretta Eastern Lechtal Alps - Ammergau Alps Samnaun Mountains Mieming Mountains moderate moderate 2 3 2 dp6 dp2 wind_drifted_snow N NW NE E SE treeline gliding_snow S SW W E SE 2400 steady 2018-12-17T23:00:00Z 2018-12-18T23:00:00Z Fresh wind slabs represent the main danger.

In the west and in the north avalanche prone locations are more prevalent and the danger is greater. Avalanches can be released in the old snowpack in isolated cases. Backcountry touring calls for experience in the assessment of avalanche danger. 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. The avalanche prone locations are sometimes covered with fresh snow and are barely recognisable because of the poor visibility. The snowpack will be subject to considerable local variations. Faceted weak layers exist in the old snowpack on steep shady slopes. Whumpfing sounds can indicate the danger. At low and intermediate altitudes thus far only a little snow is lying. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2018-12-17/2018-12-16_16-03-49/adb2294c-b1fe-45d2-998b-6f0d50a08bc4.jpg website Link to region on the website https://avalanche.report/bulletin/2018-12-17?region=adb2294c-b1fe-45d2-998b-6f0d50a08bc4 2018-12-16T16:03:49Z 2018-12-16T23:00:00Z 2018-12-17T23:00:00Z Avalanche.report https://avalanche.report Brandenberg Alps Eastern Deferegger Alps Western Kitzbühel Alps Schober Mountains Eastern Kitzbühel Alps Lienzer Dolomites moderate moderate 2 3 2 dp6 wind_drifted_snow N NW NE E SE treeline steady 2018-12-17T23:00:00Z 2018-12-18T23:00:00Z Fresh wind slabs represent the main danger.
