As a consequence of fresh snow and a strong to storm force southwesterly wind, sometimes easily released wind slabs formed in particular at intermediate and high altitudes. The wind has transported the old snow. In particular transitions from a shallow to a deep snowpack are dangerous. The number and size of avalanche prone locations will increase with altitude. Remotely triggered and natural avalanches are possible in isolated cases. Snow sport activities outside marked and open pistes call for meticulous route selection. The avalanche prone locations are prevalent and are barely recognisable because of the poor visibility. The wind slabs represent the main danger. As the penetration by moisture increases more small and medium-sized gliding avalanches are possible below approximately 2400 m. The fresh and older wind slabs remain for the foreseeable future prone to triggering in all aspects above approximately 2000 m. As a consequence of the southerly wind the wind slabs will increase in size additionally. They are lying on soft layers. On wind-loaded slopes a precarious avalanche situation will be encountered over a wide area. The wind will be storm force. The snow sport conditions outside marked and open pistes are precarious. dangerRatingMap Simplified danger rating map of the region https://avalanche.report/albina_files_local/2019-12-18/2019-12-18_07-00-00/38d9a614-569d-48aa-b49e-a378ff5bfcd2.jpg website Link to region on the website https://avalanche.report/bulletin/2019-12-18?region=38d9a614-569d-48aa-b49e-a378ff5bfcd2 2019-12-18T07:00:00Z 2019-12-17T23:00:00Z 2019-12-18T23:00:00Z Avalanche.report https://avalanche.report Val Müstair Alps Langtaufers considerable treeline considerable 2 3 3 moderate 1 2 moderate treeline moderate 2 2 3 low 1 1 wind_drifted_snow N SE E NE NW 2200 persistent_weak_layers W N SE SW E NE S NW steady 2019-12-18T23:00:00Z 2019-12-19T23:00:00Z Wind slabs and weakly bonded old snow require caution.
