In the southern regions skies will be heavily overcast. On Monday, precipitation is anticipated, to start with in the Valais
sector of the Main Alpine Ridge and in western Ticino. On Tuesday, snowfall is expected which will be intensive on the Main
Alpine Ridge and southwards therefrom. The snowfall level on Monday will still lie at 2600 m, subsequently it will descend
to 2000 m by Tuesday evening. In the northern regions, foehn-induced bright intervals are expected on Monday. On Tuesday,
snowfall is expected, including in the northern regions above approximately 2000 m.
On Monday, a storm-strength southerly wind will be blowing in all regions of Switzerland. On Monday night, the wind will incrementally
slacken off, to start with in the western regions, subsequently also in the eastern regions.
In the southern regions the danger of dry-snow avalanches will increase significantly at elevated altitudes. On Tuesday it
is currently assumed that Danger Level 4 (High) will be reached. Above approximately 2500 m, naturally triggered dry-snow
avalanches can be expected as a result of the fresh snow and strong-to-storm strength winds; and wet-snow avalanches below
2500 m, as a result of the intensive rainfall. In the northern regions, the avalanche danger levels are not expected to change
significantly on Monday; on Tuesday danger levels will increase as a result of the fresh snow.
