👉ATTENTION - BULLETIN VALID FROM MARCH 16 TO 18👈
Conditions for the weekend will be rather crusty in the mountains. Solar warming may not be enough to greatly improve conditions. Watch out for the passage of a low-pressure system from Sunday to Monday, which could bring enough snow to create new wind slabs.

Snowpack Summary
Warm temperatures during the day and refreezing at night have created a crust on the 20 to 25 cm of wet snow that fell at the start of the week. This situation is more or less amplified depending on the slope's orientation to the sun.
This wet snow rests either directly on the ground, or on a refreezing crust that is present at all elevations and on all slopes. With the warmth that accompanied the precipitation, the adhesion of the new snow to the crust is quite good. The wind has greatly redistributed the snow in the alpine region, creating great spatial variability.
The average height of the snowpack is around 100 cm, but is highly variable from sector to sector. Some slopes are back to rock...
