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. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files_local/2019-12-13/2019-12-12_16-00-00/0b3443f6-c2d6-41c5-895b-10805c896633.jpg website Link to region on the website https://avalanche.report/bulletin/2019-12-13?region=0b3443f6-c2d6-41c5-895b-10805c896633 2019-12-12T16:00:00Z 2019-12-12T23:00:00Z 2019-12-13T23:00:00Z Avalanche.report https://avalanche.report Glockner Range Eastern Deferegger Alps Schober Mountains Lienzer Dolomites Glockturm Range Weißkugel Range Gurgler Range Central Stubai Alps Northern Zillertal Alps Venediger Range Northern Oetz and Stubai Alps Eastern Rieserferner Mountains Sexten Dolomites Eastern Pfunderer Mountains Durreck Range Val Müstair Alps Western Rieserferner Mountains Langtaufers Western Deferegger Alps Schnals Ridge Ortler Range Southern Stubai Alps Ulten Valley Southern Zillertal Alps and High Tauern Eastern Nonsberger Alps Saldurn-Mastaun Ridge Northern Dolomites of Fiemme Texel Mountains Gröden Dolomites Sarntal Alps Prags Dolomites Western Pfunderer Mountains Latemar Southern Adamello Primiero - Pale di S.
