Faceted weak layers exist in the bottom section of the old snowpack here. As a consequence of a strong to storm force wind, sometimes easily released wind slabs formed in the last few days in particular above the tree line. In particular transitions from a shallow to a deep snowpack are dangerous. Remotely triggered avalanches are possible in isolated cases. The avalanche prone locations are barely recognisable because of the poor visibility. The various wind slabs are to be evaluated with care and prudence in particular in very steep terrain. They are lying on soft layers. On wind-loaded slopes a precarious avalanche situation will be encountered over a wide area. 2019-12-18T16:00:00Z 2019-12-18T23:00:00Z 2019-12-19T23:00:00Z 3 2 drifting snow gliding snow Wind slabs require caution. 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. In particular transitions from a shallow to a deep snowpack are dangerous. The number and size of avalanche prone locations will increase with altitude. 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 2600 m. The fresh and older wind slabs remain for the foreseeable future prone to triggering in all aspects above approximately 2200 m. They are lying on soft layers. On wind-loaded slopes a precarious avalanche situation will be encountered over a wide area. The avalanche conditions are to some extent critical. 2019-12-18T16:00:00Z 2019-12-18T23:00:00Z 2019-12-19T23:00:00Z 2 DP2 DP6 gliding snow drifting snow Gliding snow requires caution. Wind slabs at high altitude. As the moisture increases small to medium-sized gliding avalanches and moist snow slides are possible. This applies in particular on steep sunny slopes below approximately 2600 m as well as on shady slopes at low and intermediate altitudes, especially in the regions with a lot of snow. Caution is to be exercised in areas with glide cracks. <br/> In addition the fresh and older wind slabs should be taken into account. These can be released, especially by large additional loads, especially on northwest to north to northeast facing aspects above approximately 2400 m. The avalanches are rather small. The avalanche prone locations are clearly recognisable to the trained eye. <br/> Weak layers in the old snowpack can still be released in isolated cases in particular in areas where the snow cover is rather shallow. This applies in particular on very steep sunny slopes above approximately 2500 m. Avalanches can be released, mostly by large loads and reach medium size. These avalanche prone locations are rare and are barely recognisable, even to the trained eye. The fresh and older wind slabs are lying on soft layers in particular on shady slopes at high altitude. Faceted weak layers exist in the top section of the snowpack on steep sunny slopes, in particular above approximately 2500 m. The snowpack will be subject to considerable local variations at high altitudes and in high Alpine regions. At low and intermediate altitudes the snow is moist, also on sunny slopes below approximately 2600 m. Slight increase in avalanche danger as a consequence of the precipitation. 2019-12-18T16:00:00Z 2019-12-18T23:00:00Z 2019-12-19T23:00:00Z 2 DP2 DP6 gliding snow drifting snow Gliding snow requires caution.

Below approximately 1800 m the snow is wet. The mostly small wind slabs can be released even by a single winter sport participant. They are to be found in particular adjacent to ridgelines and generally in the high Alpine regions. Below approximately 1800 m mostly small natural loose snow slides are possible. The mostly small wind slabs represent the main danger. They are to be evaluated with care and prudence in particular on steep shady slopes above approximately 1800 m. Below approximately 1800 m the snow is wet. The avalanche danger will persist. 2019-12-18T16:00:00Z 2019-12-18T23:00:00Z 2019-12-19T23:00:00Z 2 DP2 DP6 gliding snow drifting snow Gliding snow requires caution. Wind slabs at high altitude.

As a consequence of a strong to storm force wind, sometimes deep wind slabs formed in particular adjacent to ridgelines and in gullies and bowls. The avalanche prone locations are to be found in all aspects above approximately 2000 m. The wind slabs represent the main danger. They can be released even by a single winter sport participant. Mostly avalanches are medium-sized. The number and size of avalanche prone locations will increase with altitude. They are quite prevalent and are barely recognisable because of the poor visibility. Snow sport activities outside marked and open pistes call for meticulous route selection. As the penetration by moisture increases more small and medium-sized gliding avalanches are possible below approximately 2400 m. The mostly small wind slabs of the last few days represent the main danger. They are to be evaluated with care and prudence in all aspects above approximately 1800 m.

The fresh and somewhat older wind slabs represent the main danger. The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m. Caution is to be exercised in particular adjacent to ridgelines. Such avalanche prone locations are rare and are clearly recognisable to the trained eye. The fresh and older wind slabs are lying on soft layers on shady slopes at high altitude. These have bonded quite well with the old snowpack. The snowpack will be moist at low and intermediate altitudes. This also applies on steep sunny slopes at high altitude. Thus far only a little snow is lying. The avalanche danger will persist.
