New wind-driven instabilities. Triggering by people: rare small wind-driven instabilities on the north-facing slopes above 2600 m in the first few centimeters of fresh snow expected by Sunday morning. These instabilities become a little more frequent over the course of the day with transport by a fairly strong southwesterly wind at altitude. These slabs have a brittle or dense appearance and can be triggered by the passage of a pedestrian or skier. These rare small slabs can cause small avalanches, size 1. Natural releases: - Rare small releases in wind-blown snow cannot be ruled out near ridgelines and slope breaks, in the north sector above 2700 m over the course of the day with wind transport and thickening of the slabs. Small avalanches, size 1.- Rare small loose-snow slides in steep, sunny terrain during the day.

Snowpack: deficient at all elevations, with no base layer below 2400/2700 m; the meager recent snowfall offers little reassurance. Skiable: largely not skiable except for the highest north-facing and grassy slopes of the massif above 2500/2700 m. Snow quality: light powder from 2000 m; the snowfall from Saturday night to Sunday provides 3/10 cm of wind-blown fresh snow without a base layer at 2200 m. In the north, the thickness of recent snow becomes a little more significant from 2600 m (10/20 cm), then rapidly 20/40 cm from 2800 m. Base layer from 2500/2700 m, crusted around 2600/2800 m.
