New snow and wind slabs represent the main danger. The new snow and wind slabs are prone to triggering in all aspects. As a consequence of new snow and strong wind the wind slabs will increase in size additionally as the day progresses. Avalanches can in many places be released very easily and reach large size in isolated cases. On wind-loaded slopes natural dry avalanches are to be expected. Exposed parts of transportation routes are endangered in isolated cases. Additionally in isolated cases avalanches can be released in the old snowpack and reach quite a large size. This applies in particular on steep shady slopes above approximately 2200 m. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Backcountry touring calls for extensive experience and great restraint. Up to 40 cm of snow will fall until the evening. The sometimes storm force wind will transport the snow. The brittle wind slabs will be deposited on unfavourable layers. The old snowpack is faceted; its surface consists of loosely bonded snow. As a consequence of low temperatures the snowpack can not consolidate. Wind slabs are to be assessed critically. 2021-01-13T16:00:00Z Avalanche.report 2021-01-13T23:00:00Z 2021-01-14T23:00:00Z Avalanche.report 4 2 DP6 DP1 drifting snow old snow new snow steady 2021-01-14T23:00:00Z 2021-01-15T23:00:00Z Wind slabs represent the main danger. The fresh and older wind slabs are prone to triggering in all aspects above the tree line. In the course of the day the wind slabs will increase in size additionally. Avalanches can in many places be released easily and reach medium size. Avalanches can penetrate deep layers and reach medium size. This applies in particular on steep shady slopes above approximately 2000 m. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Backcountry touring calls for extensive experience and restraint. Over a wide area 20 to 40 cm of snow, and even more in some localities, will fall until late morning. The strong wind will transport the fresh and old snow significantly. The brittle wind slabs will be deposited on soft layers. The old snowpack is faceted; its surface consists of loosely bonded snow. As a consequence of low temperatures the snowpack can not consolidate. Faceted weak layers exist in the bottom section of the snowpack at high altitudes and in high Alpine regions. Further increase in avalanche danger as a consequence of new snow and wind. 2021-01-13T16:00:00Z Avalanche.report 2021-01-13T23:00:00Z 2021-01-14T23:00:00Z Avalanche.report 4 2 DP6 DP1 drifting snow old snow new snow steady 2021-01-14T23:00:00Z 2021-01-15T23:00:00Z Fresh wind slabs require caution. Avalanche prone weak layers exist in the old snowpack above the tree line. As a consequence of the strong to storm force northwesterly wind, fresh snow drift accumulations will form. As a consequence of the new snow the avalanche prone locations will become more prevalent during the night. These are in some cases quite large and can be released easily. Avalanches can to an increasing extent be released, even by a single winter sport participant and reach medium size. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls above the tree line. In isolated cases avalanches can be triggered in the faceted old snow and reach medium size in some cases. This applies in particular on very steep shady slopes above the tree line, as well as at transitions from a shallow to a deep snowpack. Over a wide area 30 to 50 cm of snow, and even more in some localities, has fallen in all altitude zones. The old snowpack is faceted; its surface consists of loosely bonded snow. The northwesterly wind will transport the new snow and, in some cases, old snow as well. In the course of the day the wind slabs will increase in size appreciably. The brittle wind slabs will be deposited on the unfavourable surface of an old snowpack. As a consequence of low temperatures the snowpack can not consolidate. Faceted weak layers exist in the bottom section of the snowpack at high altitudes and in high Alpine regions. The avalanche danger will persist. Further increase in danger of dry avalanches as a consequence of new snow and strong wind. 2021-01-13T16:00:00Z Avalanche.report 2021-01-13T23:00:00Z 2021-01-14T23:00:00Z Avalanche.report 3 2 DP5 DP8 drifting snow old snow drifting snow steady 2021-01-14T23:00:00Z 2021-01-15T23:00:00Z Increase in avalanche danger as a consequence of new snow and strong wind. New snow and wind slabs represent the main danger. The new snow and wind slabs are prone to triggering in all aspects, also below the tree line. As a consequence of new snow and strong wind the wind slabs will increase in size additionally as the day progresses. Avalanches can in many places be released very easily and reach large size in isolated cases. Natural avalanches are possible on wind-loaded slopes. In the regions neighbouring those that are subject to danger level 4 (high) the avalanche danger is higher. Additionally in isolated cases avalanches can also penetrate deep layers. Remotely triggered avalanches are possible. Especially places where surface hoar has been covered with snow are treacherous. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. In addition a latent danger of gliding avalanches exists. Backcountry touring calls for great caution and restraint. In the north and in the northwest 20 to 30 cm of snow, and even more in some localities, will fall until the evening, in particular along the border with Tirol and Begin: South Tyrol. In the southeast a little new snow. The sometimes storm force wind will transport the new snow significantly. The brittle wind slabs will be deposited on unfavourable layers. Precarious weak layers exist in the top section of the snowpack. As a consequence of low temperatures the snowpack can not consolidate. Towards its base, the snowpack is well consolidated. The avalanche conditions are to some extent treacherous. Wind slabs are to be evaluated critically. 2021-01-13T16:00:00Z Avalanche.report 2021-01-13T23:00:00Z 2021-01-14T23:00:00Z Avalanche.report 2 2 drifting snow new snow increasing 2021-01-14T23:00:00Z 2021-01-15T23:00:00Z Slight increase in danger of dry avalanches as a consequence of new snow and strong wind. The avalanche prone locations for dry avalanches are to be found in particular on steep shady slopes, especially adjacent to ridgelines above the tree line. The avalanche prone locations are quite prevalent but are easy to recognise. Thus far only a little snow is lying below approximately 1600 m. Hardly any weak layers exist in the snowpack. Moderate, level 2. 2021-01-13T16:00:00Z Avalanche.report 2021-01-13T23:00:00Z 2021-01-14T23:00:00Z Avalanche.report 3 1 DP6 DP8 drifting snow old snow steady 2021-01-14T23:00:00Z 2021-01-15T23:00:00Z Wind slabs represent the main danger. The new snow and wind slabs are prone to triggering in all aspects above the tree line. As a consequence of the sometimes storm force wind the wind slabs will increase in size additionally as the day progresses. Avalanches can in many places be released easily and reach medium size. Avalanches can additionally be released in deeper layers also. The avalanche prone locations are barely recognisable. Remotely triggered avalanches are possible. Especially places where surface hoar has been covered with snow are treacherous. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. In addition a latent danger of gliding avalanches exists. Backcountry touring calls for caution and restraint. 5 to 10 cm of snow will fall until the evening. The strong wind will transport the fresh and old snow significantly. The brittle wind slabs will be deposited on soft layers. Precarious weak layers exist in the top section of the snowpack. As a consequence of low temperatures the snowpack can not consolidate. Towards its base, the snowpack is well consolidated. Hardly any decrease in avalanche danger. 2021-01-13T16:00:00Z Avalanche.report 2021-01-13T23:00:00Z 2021-01-14T23:00:00Z Avalanche.report 3 1 DP6 DP8 drifting snow old snow steady 2021-01-14T23:00:00Z 2021-01-15T23:00:00Z Fresh wind slabs require caution. Weak layers in the upper part of the snowpack are treacherous. Dry avalanches can be triggered in the weakly bonded old snow and reach large size in isolated cases. Remotely triggered avalanches are possible. Avalanche prone locations for dry avalanches are to be found in all aspects above the tree line. The avalanche prone locations are barely recognisable. Especially places where surface hoar has been covered with snow are treacherous. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. The fresh wind slabs are easy to recognise but prone to triggering. The prevalence of such avalanche prone locations will increase with altitude, caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. In addition a latent danger of gliding avalanches exists. Meticulous route selection is important. Precarious weak layers exist in the top section of the snowpack. The somewhat older wind slabs are lying on surface hoar in some places. The northwesterly wind will transport the loosely bonded old snow. In the course of the day the wind slabs will increase in size moderately. The fresh wind slabs will be deposited on soft layers. As a consequence of low temperatures the snowpack can not consolidate. Towards its base, the snowpack is well consolidated. Gradual increase in danger of dry avalanches as a consequence of new snow and wind, especially in the north.
