Significant increase in danger of dry avalanches as a consequence of new snow and strong wind. The fresh and somewhat older wind slabs can be released easily or naturally in all aspects. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. In some cases the avalanches are large. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Extensive experience in the assessment of avalanche danger is required. Over a wide area 15 to 30 cm of snow, and even more in some localities, will fall on Monday. As a consequence of a strong wind from southerly directions, avalanche prone wind slabs will form in all aspects. In many cases wind slabs are lying on soft layers, this also applies below the tree line. In its middle, the snowpack is well consolidated. Towards its base, the snowpack is faceted, especially on shady slopes above the tree line, as well as in all aspects in high Alpine regions. The avalanche danger will persist. 2020-12-27T16:00:00Z Avalanche.report 2020-12-27T23:00:00Z 2020-12-28T23:00:00Z Avalanche.report 3 2 DP6 DP1 drifting snow new snow old snow steady 2020-12-28T23:00:00Z 2020-12-29T23:00:00Z Wind slabs are to be evaluated critically. Increase in avalanche danger as a consequence of new snow and strong wind. The fresh and somewhat older wind slabs can be released easily. or in isolated cases naturally, in all aspects, caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Mostly the avalanches are medium-sized. The number and size of avalanche prone locations will increase with altitude. <br/> Weak layers in the lower part of the snowpack can still be released in isolated cases by individual winter sport participants. Caution is to be exercised in particular on steep shady slopes above approximately 2200 m, especially in areas where the snow cover is rather shallow, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. 5 to 15 cm of snow, and even more in some localities, will fall on Monday. The strong wind will transport the fresh and old snow. In many cases wind slabs are lying on soft layers, also below the tree line. <br/> Steep shady slopes: The old snowpack will be prone to triggering in some places. Towards its base, the snowpack is faceted and weak. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack are a clear indication of a weakly bonded snowpack. The avalanche danger will persist. 2020-12-27T16:00:00Z Avalanche.report 2020-12-27T23:00:00Z 2020-12-28T23:00:00Z Avalanche.report 2 1 DP6 drifting snow steady 2020-12-28T23:00:00Z 2020-12-29T23:00:00Z Wind slabs are to be evaluated with care and prudence. The fresh and somewhat older wind slabs are in some cases prone to triggering above the tree line, especially adjacent to ridgelines and in gullies and bowls. Mostly avalanches are only small but can be released also by a single winter sport participant. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. As a consequence of new snow and a strong wind from variable directions, mostly small wind slabs will form above the tree line. In some places wind slabs are lying on soft layers, especially adjacent to ridgelines and in gullies and bowls. The avalanche danger will persist.
