Avalanche Forecast
Regions: Haines Pass, Tutshi, Wheaton, White Pass East, White Pass West, Yukon.
Continue to assess for wind slabs in exposed, alpine terrain features.
Confidence
Moderate
Avalanche Summary
A group of skiers remote-triggered a size 2 avalanche on a wind-loaded convex roll in the Wheaton area on Sunday. Check out the associated MIN here.
If you go into the backcountry, please submit your observations to the Mountain Information Network.
Snowpack Summary
A widespread surface crust likely exists up to roughly 1500 m.
At higher elevations recent snow has been redistributed by winds from various directions. Deeper deposits of wind slabs can be found in exposed terrain.
In some areas, a weak layer of facets or surface hoar may persist, down approximately 50 to 80 cm from the surface.
