The weather conditions - new snow, winds and rising temperatures - are combined to reduce the stability of the snowpack. It seems that winter conditions are still present in alpine terrain. Evaluate the slopes carefully before setting off.
About 40 cm of snow have accumulated since Tuesday evening, and the prevailing winds are favouring the formation of wind slabs, whose reactivity remains difficult to predict.
Recently fallen snow lies on a crust. At lower altitudes, it is moist and reacts in places to skiers.
No new avalanches observed or reported.
If you're out and about in the backcountry, please share your observations on the RIM ( Réseau d'Information en Montagne ).
Up to 40 cm of fresh snow (moist below 600 m) lies on a widespread refreezing crust. The upper part of the snowpack, up to 90 cm deep, is moist. The middle of the snowpack consists of alternating well-consolidated snow and refreezing crusts.
There is considerable spatial variability in the alpine zone and at the treeline (presence of rocks, ice, blown snow). At mid-mountain, snowpack thickness varies from 80 to 200 cm.
