The weak overnight refreezing, along with the rain and warmth, could weaken the cornices on Sunday.
FINAL BULLETIN OF THE SEASON – VALID FOR APRIL 26 AND 27, 2025
There is some uncertainty regarding the impact of Saturday’s weather system on avalanche danger. Depending on the amounts that fall, the new moist snow combined with rain could show signs of instability.
The weak overnight refreezing, along with the rain and warmth, could weaken the cornices on Sunday.
Rain could destabilize the surface snow below and near the treeline. The new wet snow in alpine areas could be easily weakened by additional warmth or rainfall on Sunday. Extra caution is advised on steep slopes.
No new avalanches have been observed or reported.
If you are out and about in the hinterland, please share your observations with the RIM ( Réseau d'Information en Montagne ).
Rain at lower elevations and wet snow in alpine terrain expected on Saturday will fall on a typical spring snowpack: moist and subject to freeze-thaw cycles on south-facing slopes, colder and drier—sometimes even icy—on north-facing slopes.
Conditions are highly variable in alpine areas and near the treeline.
At mid-mountain elevation, snowpack depth ranges from 60 to 160 cm.
