The alpine rating is Storm Slabs and Persistent Slabs.
, the treeline rating is , and the below treeline rating is Known problems include⚠️Dangerous avalanche conditions⚠️
The snowpack is primed for human triggering. Careful snowpack evaluation, cautious route-finding, and conservative decision-making is essential.
Summary
Confidence
Moderate
Avalanche Summary
Natural, skier, and remotely triggered avalanches up to size 3.5 have been reported throughout the region daily over the past week. Many of these avalanches failed on layers below the recent storm snow, the mid-February weak layer, and the early-February facet/crust layer.
While natural activity has begun to taper off, human triggering is expected to remain a serious concern.
Snowpack Summary
Up to 70 cm of recent snow has accumulated over the last week. The new snow has formed touchy slabs, especially in wind-exposed terrain and may sit over a variety of weak interfaces.
A weak layer of facets, surface hoar, and/or a crust from mid-February may be found down 40 to 80 cm.
A widespread crust formed in early February is buried by roughly 60 to 120 cm and extends up to 2400 m. Weak facets have been found above this crust. This layer continues to produce concerning avalanches across the province.
The lower snowpack is generally well-settled and strong.

Terrain and Travel Advice
- Keep in mind that human triggering potential persists as natural avalanching tapers off.
- Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
- Remote triggering is a concern, watch out for adjacent and overhead slopes.
- Use conservative route selection. Choose simple, low-angle, well-supported terrain with no overhead hazard.
Problems
Storm Slabs
Recent snow accompanied by strong wind has formed touchy slabs that may sit over various weak layers. These slabs remain reactive to human triggering and have the potential to travel full path.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
Buried weak layers remain sensitive to human triggering and could result in very large avalanches. It is possible to trigger these layers remotely and avalanches have the potential to run full path, so watch your overhead exposure.
Aspects: All aspects.
