Carefully assess the bond between wind slabs and the underlying crust before committing to terrain.

Moderate

Avalanche Summary

No new avalanches were reported on Thursday. We suspect at the peak of the rain event Thursday night a natural avalanche cycle would have occurred at treeline on all aspects.

Please continue to post your observations and photos to the Mountain Information Network.

Snowpack Summary

As the freezing level falls a new crust will form on all aspects at treeline. Below treeline the snow surface will likely still be moist and saturated. At the higher elevation terrain wind slab could have formed on all aspects.

Wind this week has generally been southerly but there was also a period of strong northerly wind in the region Thursday night. Watch for wind slab on all aspects.

Wind slabs may not bond well to the underlying crust making them more reactive.
