Snowpack

On northern slopes, the snowline is around 2000 m and on southern slopes between 2400 m and 2800 m. At high altitudes, there are patches of continuous snowpack in gullies and bowls on shady slopes. The snow is significantly deeper above 2800 m.

On Saturday, precipitation set in in the south. Conditions had previously been generally dry and sunny in the mountains over the last two weeks. While the snow had largely melted on steep south-facing slopes at high altitudes over this period, on shady slopes and generally in the high Alpine regions, the snowpack had begun to become faceted. Distinct weak layers had formed. Avalanches can easily be triggered where fresh and drifted snow falls on this snowpack.

Outlook

A further 5 to 20 cm of snow will fall above 1000 m in the north by the night to Tuesday with sometimes strong north to northeasterly winds. On Tuesday and Wednesday, conditions will be mostly sunny with zero-degree levels between 1000 m and 1400 m. The wind will be light to moderate and shift from northeast to southwest on Wednesday.

Avalanche risk will hardly change on Tuesday and will decrease slowly on Wednesday.
