⚠️Dangerous avalanche conditions⚠️
The snowpack is primed for human triggering. Careful snowpack evaluation, cautious route-finding, and conservative decision-making is essential.

Avalanche Summary
Natural, skier, and explosive-triggered avalanches up to size 3 have continued to be reported daily throughout the region since early in the week. Avalanches have slid on layers in the upper snowpack.
While natural activity is beginning to taper off, human triggering is expected to remain a serious problem.
Snowpack Summary
Up to 100 cm of snow has accumulated over the last week. This recent snow has formed touchy slabs, especially in wind-exposed terrain. The recent snow sits atop various weak layers of facets, surface hoar, and/or a crust.
A widespread crust formed in early February is buried 70 to 120 cm deep. Facets have been found above this crust. This layer continues to produce many concerning avalanches across the province.
The mid and lower snowpack is largely faceted with depth hoar and a crust found at the bottom of the snowpack in many areas.
Weather Summary

Partly cloudy with isolated flurries bringing a trace of snow. <20 km/h southwest ridgetop wind. Treeline temperature -9 °C.
Tuesday
A mix of sun and cloud. <20 km/h west ridgetop wind. Treeline temperature -12 °C.
Wednesday
Sunny. <20 km/h northwest ridgetop wind. Treeline temperature -12 °C.

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.
- Be aware of the potential for large, destructive avalanches due to the presence of deeply buried weak layers.
Problems
Storm Slabs
Recent snow accompanied by strong wind has formed touchy slabs that may sit over a weak layer. These slabs will 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 very 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.
