All aspects
Considerable (3) No change
The danger level rises from 2 (Moderate) to 3 (Considerable) above 3000 m, up from 2800 m previously. Wind slabs are now forming above 2800 to 3000 m on all aspects and are easy to trigger, replacing the small instabilities seen before. AI summary comparing the two official bulletins.

Slabs forming at high altitude, under southwesterly winds.
With the snowfall at high altitude, small to medium-sized natural avalanches.
Friday 13 November
Considerable (3) No change
Danger level 3 (Considerable)
Danger stays Considerable at high altitude. Weather returns to dry conditions. The slabs formed on Thursday remain sensitive at the highest elevations and on west, north and east-facing slopes.
New snow
Snowfall (New Snow Problem). Fresh snowfall forming a soft slab on top of existing layers.
Persistent weak layer
Persistent Weak Layer (Old Snow Problem). A buried weak layer (facets, depth hoar) causing unpredictable, large avalanches.
Slabs are forming above 2800 to 3000 m on all aspects, under the windblown snowfall of this Thursday. They are more numerous and sensitive in the heart of the massif, especially on west, north and east-facing slopes, where the late October base layer has probably changed into angular grains. Easily triggered, these slabs can produce small to medium avalanches (size 1 to 2). On Thursday afternoon, fractures may be deeper and involve large volumes of snow, especially in accumulation zones or loaded gullies. Below 2800 to 3000 m, the accidental risk is more limited. The snowpack is often thin and well soaked by rain.
New snow avalanches of size 1 to 2 are possible during snowfall, on steep slopes above 2800 to 3000 m.
Measured 11 Nov 2026
Following recent snowfall, the snow cover is becoming adequate for early November. Between 15 and 40 cm is recorded in the 2000 to 3000 m band on northern slopes. The Nivôse des Écrins weather station (2970 m) reports 35 cm of snow. Skiable snow limit: from 2000 to 2200 m on some shaded alpine pastures, but there is no base layer except above 2800 to 3000 m on fully north-facing slopes. Rocks remain poorly buried and glaciers are heavily crevassed.
The snow is often wetted by rain up to about 2800 m. At higher altitude a deeper layer of new snow is starting to form (30 to 40 cm, locally more). This snow is hardened by wind on exposed slopes, but cold and light in sheltered places.
Grey and rainy weather. Heavy snowfall above 2800 to 3000 m, with 30 to 50 cm expected by this evening.
