Thick wind slabs are present and continue to develop at the top of the eastern slopes (NE-E-SE) and in cross loaded areas at treeline.
They are particularly to watch out for on steep unsupported slopes and convex rolls.

Wind slabs continue to develop with sustained westerly winds. They are found at the top of eastern slopes (NE-E-SE) in the alpine and in cross loaded areas at treeline. They rest on the widespread melt-freeze crust, which constitutes a good sliding plane.
No new avalanches were observed or reported.

About 15 to 25 cm of new snow has accumulated on the surface, for a total of 20-35 cm above the widespread melt-freeze crust. In downwind areas, accumulations can reach 40 to 60 cm thick in the form of wind slabs that continue to develop. The melt-freeze crust is present on the surface or barely buried in wind exposed areas in the alpine and at treeline. Below the melt-freeze crust, the middle and the base of the snowpack are well consolidated.
In general, the height of the snowpack varies from 90 to 110 cm in the valley to 130 to 180 cm at treeline.
