INSTABILITY INCREASING WITH SNOWFALL Triggering: above 2800/3000 m, existing slab structures, others forming with the wind-driven snowfall. Present in all aspects. Easy to trigger by a skier, sometimes from a distance (presence of persistent weak layers). Size generally medium, even large in the north-facing wide areas at very high altitude. Lower down, some slab structures forming, particularly in wind snow accumulation zones. Instabilities easy to trigger. Size generally small. Natural releases: at high altitude, some releases on steep slopes, sometimes in the form of a slab, especially during the snowfall from Saturday night to Sunday, more rarely on Sunday during the day with wind transport. Size medium, even large.

Snowpack assessment: good snow cover at high altitude for the season. Snow measurements: 9 cm near Madame Carle at 1870 m, 52 cm at the Nivose of the Écrins at 2970 m. Skiable snow cover limit: there is little sublayer below 2500 m. Stones remain only slightly buried. Condition of the surface snow: fresh snow locally wind-affected, in sufficient quantity in the heart of the massif, resting on hard/re-frozen snow up to about 2800 m, and on dry snow worked by the wind at higher altitude.
