Danger level


Avalanche Problem
Persistent weak layer


The danger of Avalanche is low.

The snowpack is mostly stable. In arid areas above the forest line, weak layers may be present in the snowpack. In a few places in the high alpine regions, a small, clustered Avalanche may be triggered under higher loads. Some creeping of dry, untracked new snow is possible.

Snowpack

dp.4: cold following warm / warm following cold

Snowpack is mostly stable, with significant snowmelt on sunny slopes. On the sunny slopes, the old snow base is hard in many places. In the osoles, weak layers may be present in the Old snowpack. Up to 10 cm of new fallen snow has fallen on the old snow base, with the snowfall level around 1800 m above altitudes.

Tendency

Friday will see more clarity in the mountains, with a weak to moderate westerly wind that will weaken during the day. Temperatures will be 4 °C at 1500 m and -1 °C at 2500 m.
