Middle Lys Valley

Intensive snowfall to low altitudes: Medium-sized and large dry avalanches are to be expected.

Intensive snowfall to low altitudes: Medium-sized and large dry avalanches are to be expected.

Over a wide area 80 to 120 cm of snow will fall until the early morning above approximately 1000 m. This snow is bonding poorly with the old snowpack. The moderate wind will transport the new snow. The large quantity of fresh snow as well as the wind slabs can be released naturally. In particular on steep shady slopes numerous occasionally large avalanches are to be expected in particular from starting zones at higher altitudes. The peak of avalanche activity will be reached during the second half of the night probably. Powder avalanches are to be expected. In the typical avalanche paths the dry avalanches can reach as far as the valley bottom. Exposed parts of transportation routes can be endangered in some localities here. Without question, it is inadvisable to engage in ski touring, freeriding and snowshoe hiking.

In these regions the snowfall level will drop to approximately 500 m. The new snow is bonding poorly with the old snowpack. Especially steep shady slopes high altitudes and the high Alpine regions: Towards its surface, the snowpack is unfavourably layered. Weak layers exist in the old snowpack here. Adjacent to ridgelines and in pass areas as well as at high altitude snow depths vary greatly, depending on the infuence of the wind.

Strong northwesterly wind: On wind-loaded slopes the likelihood of avalanches is high. In addition the danger of moist and wet avalanches will increase as the day progresses.
