Avalanche Summary
On Wednesday, numerous natural wind slab avalanches up to size 2 were reported. Many initiating below ridgetop as a result of strong winds depositing snow load lower onto slopes.
Snowpack Summary
Strong winds with shifting directions are building wind slabs in alpine and down into treeline. Many exposed areas scoured to previous firm surfaces. These new wind slabs have formed over previous old wind slabs or an old faceted layer.
In sheltered areas up to 40 cm of recent snow overlies a layer of buried surface hoar or a crust below 1700 m.
The rest of the snowpack is well settled.
