Weakly bonded old snow requires caution. Fresh and somewhat older wind slabs must be evaluated with care and prudence in all aspects above the tree line, especially adjacent to ridgelines and in gullies and bowls. The number and size of avalanche prone locations will increase with altitude. Avalanches can additionally in isolated cases be released in the weakly bonded old snow on steep south, southwest and west facing slopes. In areas where the snow cover is rather shallow the avalanche prone locations are more prevalent. <br/> Avalanches can as before be released, even by a single winter sport participant and reach medium size. Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger. Brittle wind slabs have formed in particular on northeast, east and southeast facing slopes. 10 to 15 cm of snow, and up to 20 cm in some localities, will fall. As a consequence of fresh snow and stormy weather the wind slabs will increase in size additionally. They are bonding poorly with the old snowpack in all aspects above the tree line. <br/> Faceted weak layers exist in the top section of the old snowpack on steep sunny slopes. As a consequence of fresh snow and stormy weather there will be an increase in the avalanche danger. 2019-12-12T16:00:00Z 2019-12-12T23:00:00Z 2019-12-13T23:00:00Z 2 1 DP6 drifting snow Wind slabs are to be evaluated critically.
