Avalanche Summary
On Tuesday, numerous wind slab and loose dry avalanches were reported up to size 2. Many occurring naturally and some rider triggered.
Snowpack Summary
Strong outflowing winds from the north east continue 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 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.
