In isolated cases avalanches can be triggered in near-to-surface layers of the old snowpack. Generally the avalanches sweep along the amounts of fresh snow and freshly generated snowdrifts from this last week.

There were isolated showers in the Valais on Friday evening. Nocturnal skies were clear for the most part. During the morning hours on Saturday it was predominantly sunny, in spite of high-altitude cloudbanks, subsequently there was convective cloud build-up.
