    Loose wet snow slides may release naturally from steep terrain at treeline and below. Wet slides in motion may gain a lot of mass as they scour isothermal snowpacks down to the ground.

Avalanche Summary

No new avalanches reported. Expect loose wet snow releases from steep terrain at treeline and below. Pockets of wind slab may be triggered by skiers or riders at higher elevations.

Snowpack Summary

30-40cm of new snow has fallen at 1800m elevation and above. Recent moderate winds have created wind slabs in alpine leeward slopes and scoured the new snow down to a hard crust on windward aspects. The snowpack continues to be moist below the crust.
