On Monday, it will be partly cloudy in the north and mostly sunny elsewhere. The zero-degree level will rise to above 3000 m during the day. The wind will be mostly moderate from westerly directions.
The danger of dry avalanches will decrease. Particularly on steep north-facing slopes in high alpine regions, avalanches can still be triggered by people. As a result of solar radiation, moist loose snow slides and avalanches are to be expected on steep slopes in high alpine regions.
On Tuesday, it will be mostly sunny and mild. The zero-degree level will rise to 4000 m. The wind will be light to moderate from westerly directions.
The danger of dry avalanches will decrease further. As temperatures rise, the snowpack will become moist up to high alpine altitudes. Small and medium-sized wet loose snow avalanches are possible. In addition to the danger of being buried, particular attention should be paid to the danger of being swept along and falling.

The new snow and wind slabs are lying on top of a weakly bonded old snowpack especially on shady slopes in high Alpine regions. Persons can release avalanches in some places, including medium-sized ones.Between Wednesday and Saturday, snowfall accompanied by moderate to strong winds was widespread at high altitudes, with the largest amounts falling in the Bernese and Valais Alps and in the Bernina region. Around half a metre of snow fell above 2800 m in these regions. In high alpine regions along the main Alpine ridge from the Monte Rosa region to the Bernina region, the fresh snow was deposited on a thin but already continuous snow cover. Faceted weak layers are present near the ground in these regions. Elsewhere, weak layers are to be expected mainly within the various layers of fresh snow and wind-drifted snow.
As the snowfall level rises to around 2600 m during the night to Sunday, the snowpack will become moist or wet over widespread areas, including at high altitudes.
