These can be released in near-surface layers and reach medium size. Avalanches can also penetrate near-ground layers of the snowpack and reach large size on west, north and east facing slopes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger. <br/> <br/> As a consequence of solar radiation loose snow avalanches are possible. This applies in particular on very steep slopes in places that are protected from the wind.", "highlights": "Outside marked and open pistes an unfavourable avalanche situation will prevail."}, "avalancheProblems": [{"aspects": ["NW", "N", "SE", "E", "W", "S", "NE", "SW"], "elevation": {"lowerBound": "treeline"}, "frequency": "many", "customData": {"ALBINA": {"avalancheType": "slab"}}, "problemType": "wind_slab", "avalancheSize": 2, "validTimePeriod": "all_day", "snowpackStability": "poor"}, {"aspects": ["NW", "N", "E", "W", "NE"], "elevation": {"lowerBound": "2200"}, "frequency": "some", "customData": {"ALBINA": {"avalancheType": "slab"}}, "problemType": "persistent_weak_layers", "avalancheSize": 3, "validTimePeriod": "all_day", "snowpackStability": "poor"}], "snowpackStructure": {"comment": "20 to 50 cm of snow fell in the last few days. <br/> The wind was violent in some cases. The northwesterly wind has transported the new snow and, in some cases, old snow as well.

The old snowpack will be weakly bonded, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes."}}}
