In sintesi

Travel will continue to be difficult on steep terrain because the rain crust is not yet buried deep enough.

    You should check the stability of the wind slabs on the January 18 rain crust before venturing out.

Snowpack Summary

The 10 cm of snow received since the slight thaw at the beginning of the week covers the rain crust of January 18 which can be very thick (up to 9 cm) in some areas! This snow was moved by moderate northwest winds on Thursday and northeast winds on Friday. The soft wind slabs up to 20 cm thick that formed at the treeline seem to us to have little reaction. As for those in the alpine, since we have no recent observations, we can only assume that they are thicker. Below the tree line, the new snow greatly reduces the feeling of skiing on glass.

Needless to say, travel in the alpine and on steep terrain is still perilous. With the snowpack still thin and many obstacles not yet covered, a slip on these icy surfaces could be disastrous. Spatial variability is important, from rock to ice to areas of greater accumulation. Generally speaking, the thickness of the snow cover varies from 50 to 100 cm depending on the sector and the altitude.
