Avalanche Summary

No recent avalanches reported.

Snowpack Summary

Thin windslabs may still exist in isolated leeward features on a variety of aspects at treeline and in the alpine while wind-exposed features have become heavily scoured.  Recent cold temperatures and clear skies are causing faceting of the upper snowpack which should be causing the remaining wind slabs to break-down.  In more sheltered areas, several centimetres of dry snow may overlie a melt-freeze crust, surface hoar, facets, or a combination of the above.  The mid and lower snowpack are generally well consolidated and there are currently no layers of concern. However, weak basal facets may still be a concern in isolated areas, especially thin snowpack areas at higher elevations.

Problems

Wind Slabs

An icon showing Wind Slabs
Thin wind slabs may still exist in isolated leeward features on a variety of aspects in wind exposed terrain.  These are generally becoming stubborn to trigger but may still possible in isolated areas.
Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.>Be cautious as you transition into wind affected terrain.>

Aspects: All aspects.

Elevations: Alpine, Treeline.
