Over a wide area over a wide area 10 to 30 cm of snow will fall above approximately 1000 m. The strong wind has transported the new snow. In some places wind slabs are lying on soft layers.

The fresh snow and the extensive wind slabs formed by the strong to storm force westerly wind can be released by a single winter sport participant. Caution is to be exercised in particular on very steep slopes, as well as at transitions from a shallow to a deep snowpack especially at high altitudes and in high Alpine regions. Avalanches can penetrate deep layers and reach dangerously large size. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Remotely triggered avalanches are possible in isolated cases. <br/> The danger of natural dry avalanches will decrease. From origins in starting zones where no previous releases have taken place only isolated avalanches are possible. In the regions exposed to a lot of wind this applies. <br/> The danger of gliding avalanches will persist. Areas with glide cracks are to be avoided as far as possible. <br/> Extensive experience in the assessment of avalanche danger is required. Over a wide area 5 to 10 cm of snow, and even more in some localities, will fall above approximately 1000 m. <br/> In the regions exposed to the foehn wind moderate northerly wind. In some places new snow and wind slabs are lying on soft layers. This applies at high altitudes and in high Alpine regions. <br/> Avalanche prone weak layers exist in the centre of the snowpack. Towards its base, the snowpack is faceted. <br/> The snowpack will be moist at low and intermediate altitudes. The avalanche danger will decrease gradually. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2021-01-31/2021-01-30_16-00-00/11016672-9a59-4404-8c9f-bdd44cde6833.jpg website Link to region on the website https://avalanche.report/bulletin/2021-01-31?region=11016672-9a59-4404-8c9f-bdd44cde6833 2021-01-30T16:00:00Z 2021-01-30T23:00:00Z 2021-01-31T23:00:00Z Avalanche.report https://avalanche.report Sexten Dolomites Eastern Pfunderer Mountains Durreck Range Western Rieserferner Mountains Western Deferegger Alps Central Stubai Alps Northern Zillertal Alps Southern Stubai Alps Ulten Valley Venediger Range Southern Zillertal Alps and High Tauern Eastern Nonsberger Alps Eastern Rieserferner Mountains Northern Dolomites of Fiemme Glockner Range Texel Mountains Gröden Dolomites Eastern Deferegger Alps Sarntal Alps Prags Dolomites Schober Mountains Western Pfunderer Mountains Lienzer Dolomites considerable treeline no_rating no_rating considerable treeline no_rating no_rating dp6 dp2 wind_drifted_snow SE SW E N W NE NW S treeline considerable considerable 2 3 3 gliding_snow E SE SW N NE W NW S 2400 considerable considerable 2 2 persistent_weak_layers E SE SW N W NE NW S treeline moderate moderate 3 2 2 steady 2021-01-31T23:00:00Z 2021-02-01T23:00:00Z Wind slabs require caution. Gliding avalanches are still possible. The fresh and older wind slabs remain prone to triggering in all aspects above the tree line. Avalanches can be released, even by a single winter sport participant and reach medium size. Additionally avalanches can also be triggered in the old snowpack and reach large size in isolated cases. <br/> The danger of natural dry avalanches will decrease. From origins in starting zones where no previous releases have taken place only isolated avalanches are possible. In the regions exposed to a lot of wind this applies. On extremely steep sunny slopes dry loose snow avalanches are possible as a consequence of solar radiation. <br/> In the regions with a lot of snow more gliding avalanches are possible, even quite large ones. <br/> Experience in the assessment of avalanche danger is important. Over a wide area 5 to 10 cm of snow, and even more in some localities, will fall above approximately 1000 m, in particular in the south. <br/> In the regions exposed to the foehn wind moderate northerly wind. In some places new snow and wind slabs are lying on soft layers. This applies in particular at high altitudes and in high Alpine regions. Avalanche prone weak layers exist in the centre of the snowpack. Whumpfing sounds indicate the danger. The snowpack will be moist at low and intermediate altitudes. The avalanche danger will decrease gradually. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files/2021-01-31/2021-01-30_16-00-00/9dab7a20-62f4-435c-ab1c-ff40baedf15d.jpg website Link to region on the website https://avalanche.report/bulletin/2021-01-31?region=9dab7a20-62f4-435c-ab1c-ff40baedf15d 2021-01-30T16:00:00Z 2021-01-30T23:00:00Z 2021-01-31T23:00:00Z Avalanche.report https://avalanche.report Brandenberg Alps Western Kitzbühel Alps Wilder Kaiser Mountains - Waidring Alps Eastern Kitzbühel Alps considerable treeline no_rating no_rating moderate treeline no_rating no_rating dp6 dp2 wind_drifted_snow SE SW E N W NE NW S treeline considerable considerable 2 3 3 gliding_snow E SE SW W S 2400 moderate moderate 1 2 persistent_weak_layers SE SW E N W NE NW S treeline moderate moderate 2 3 2 steady 2021-01-31T23:00:00Z 2021-02-01T23:00:00Z Wind slabs represent the main danger. This applies above the tree line. As a consequence of new snow and a strong wind from westerly directions, extensive wind slabs formed in the last few days above the tree line. These can in some cases be released easily especially at their margins. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. <br/> In addition in particular at low and intermediate altitudes, further gliding avalanches are possible. This applies especially in the regions with a lot of snow. <br/> Meticulous route selection is recommended. Over a wide area 5 to 10 cm of snow will fall above approximately 1000 m. <br/> Moderate northwesterly wind. <br/> In some places new snow and wind slabs are lying on soft layers. This applies in particular at high altitude. Avalanche prone weak layers exist in the centre of the snowpack. Towards its base, the snowpack is faceted.
