⚠️Dangerous avalanche conditions⚠️
Stick to low-angle terrain and be mindful of overhead hazard. Human-triggered and remote-triggered avalanches remain likely.

Moderate
Avalanche Summary
Natural, skier, and remotely triggered avalanches up to size 3.5 have been reported throughout the region daily since early last 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.
This MIN report details a scary avalanche incident southwest of Cranbrook, that has similarities to numerous recent reports throughout the interior of BC.
Snowpack Summary
Roughly 100 to 120 cm of recent snow has accumulated atop a widespread, thick crust formed in early February. Various weak layers, including facets, surface hoar and/or thin crusts have been reported roughly 0 to 20 cm above the crust. These layers continue to produce concerning avalanches across the region.
The remaining snowpack below the crust is generally well-settled and strong.
Weather Summary
Monday Night
Partly cloudy with 0 to 10 cm of snow. 10 to 30 km/h southwest ridgetop wind. Treeline temperature -12 °C.
Tuesday
Mix of sun and cloud. 10 to 30 km/h west ridgetop wind. Treeline temperature -10 °C.
Wednesday
Sunny. 10 to 30 km/h west ridgetop wind. Treeline temperature -10 °C.
Thursday
Sunny. 10 to 30 km/h west ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice
- Use conservative route selection. Choose simple, low-angle, well-supported terrain with no overhead hazard.
- Keep in mind that human triggering potential persists as natural avalanching tapers off.
- Remote triggering is a concern, watch out for adjacent and overhead slopes.
- Storm slabs in motion may step down to deeper layers resulting in large avalanches.
Problems
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.

Expected Size
Storm Slabs
Recent snow accumulation has formed touchy slabs, especially in wind-exposed terrain. These slabs remain reactive to human triggering and have the potential to travel full path.
