Persistent weak layers
- Above 2,400 m
Careful on blowing snow! Above 2400 m there are weak layers in the old snow cover. On prominent slopes, snow will slicken and creep during the day.

A small additional load can trigger a small to medium avalanche, especially near ridges where there are fresh snow drifts, especially above 1800 m. At altitudes above 2400 m, a small load can trigger a small to medium avalanche of packed snow. During the day, if the weather is sunny, the snow on the slopes will become thinner and in many places will creep down. On steep grassy slopes, the whole snow cover may creep down.
On Monday and Tuesday, more than 40 cm of snow fell above 1800 m, and up to 20 cm at lower altitudes. The snow fell on uneven ground - in some places on terrestrial ground, especially on the southern slopes on drifts of blown snow. The north-easterly wind moved the snow above the tree line and built up drifts - especially above 1800 m, where there is more dry snow. There are weak layers in the old snow cover above 2400 m.

On Saturday, daytime snow softening will be less effective, as there will be some high clouds in the middle of the day. Instability will remain in snow drifts and in avalanches above 2400 m.
