Caution is to be exercised in particular on very steep shady slopes above approximately 2200 m adjacent to ridgelines and in gullies and bowls.Since Friday extensive wind slabs formed adjacent to ridgelines and in gullies and bowls. They are clearly recognisable to the trained eye. Caution is to be exercised in particular on very steep shady slopes above approximately 2200 m. Mostly avalanches are rather small and can mostly be released by large loads. At high altitudes and in high Alpine regions the avalanche prone locations are more prevalent and larger. <br/> Weak layers in the upper part of the snowpack can be released on very steep sunny slopes, especially between approximately 2300 and 2800 m. These avalanche prone locations are rare and are barely recognisable, even to the trained eye. Avalanches are only small. <br/> In addition a latent danger of gliding avalanches exists, in particular in the regions with a lot of snow as well as along the border with Vorarlberg. <br/> Snow sport activities outside marked and open pistes call for experience in the assessment of avalanche danger and a certain restraint.The fresh and older wind slabs are lying on soft layers in particular on shady slopes at intermediate and high altitudes. These have bonded quite well with the old snowpack. Faceted weak layers exist in the top section of the old snowpack on steep sunny slopes. These can in very isolated cases be released, in particular by large loads. The snowpack will be moist at low altitude.The avalanche danger will persist.dangerRatingMapSimplified danger rating map of the regionhttps://avalanche.report/albina_files_local/2019-12-17/2019-12-16_16-00-00/60d925c3-ec6c-4b90-87ae-0af8518aaeb7.jpgwebsiteLink to region on the websitehttps://avalanche.report/bulletin/2019-12-17?region=60d925c3-ec6c-4b90-87ae-0af8518aaeb72019-12-16T16:00:00Z2019-12-16T23:00:00Z2019-12-17T23:00:00ZBrandenberg AlpsWilder Kaiser Mountains - Waidring AlpsEastern Kitzbühel Alpslowlow231low11dp6wind_drifted_snowNWNEN2200steady2019-12-17T23:00:00Z2019-12-18T23:00:00ZFresh wind slabs represent the main danger.As a consequence of a strong to storm force wind, sometimes avalanche prone wind slabs formed at high altitude.
