On Sunday, the east and south will see the last of the bright intervals, while elsewhere it will be very cloudy with light precipitation. A few centimetres of snow will fall in the north by Monday morning. The snowfall level will drop from 1400 to 800 m. On Monday, it will be mostly sunny in the mountains. There will be a light to moderate southwesterly wind.
Avalanche risk will decrease further.

"}, "avalancheProblems": [{"aspects": ["N", "NE", "E", "SE", "S", "SW", "W", "NW"], "comment": "The new snow of the last few days is lying on top of a weakly bonded old snowpack at elevated altitudes. Avalanches can in some cases be released in deep layers and reach large size. Caution is to be exercised in areas where the snow cover is rather shallow, as well as at transitions from a shallow to a deep snowpack.After this week's snowfall, the snow depths in the north and west are well above average for the time of year. In the south, they are below average.
Deeper in the snowpack, especially on shady slopes above approximately 2400 m and in the high Alpine regions in general, there are faceted weak layers in which avalanches, some large, have been triggered in recent days. In the regions exposed to heavier precipitation in the west and north, these weak layers are now thickly overlaid and are therefore no longer so easily triggered by winter sports participants. However, any avalanches may still become large. In areas with less fresh snow, avalanches are easier to trigger in these weak layers, but will not be quite as large.
With the north to northeasterly wind, snowdrift accumulations have formed at high altitudes over the last two days.
