The little new unskied snow and the presence of a solid crust near the surface maintain a LOW danger rating for the weekend. However, a low rating does not mean zero danger. Beware of isolated accumulations of wind affected snow, where the triggering of small avalanches could have serious consequences as a result of an uncontrolled slide down a steep slope and towards obstacles lower on the slope.
A small wind slab avalanche was accidentally triggered by a skier on March 2 on a cross loaded east slope at Mount Craggy in the Mont Blanc area. One person was involved and no serious injuries or consequences were reported. To view the report: https://rb.gy/d5tenu

Near the summits, the wind has redistributed the available snow, exposing the crust or ice at the surface and creating an overlay of hard wind slabs. In more sheltered places, 10 to 25 cm of low density, but intensely skied snow cover the February 17th crust about 5 cm thick which supports the weight of a person. The middle of the snowpack is well consolidated, with the January 18 crust down 40 to 70 cm below the surface. At the base of the snowpack, there is a bread of laminated crusts with decomposing snow.
In general, the height of the snowpack varies from 100 to 180 cm.
