Regions

Kootenay Boundary, Purcells, Bonnington, Grohman, Kootenay Pass, Norns, Ymir, Crawford, Moyie, St. Mary, Kokanee, Retallack, Valhalla, Whatshan.

As storm snow accumulates, avalanche hazard will rise, creating very dangerous avalanche conditions.

Step down avalanches are possible. Travel in avalanche terrain is not recommended.

Confidence

Moderate

We are uncertain due to a highly variable snowpack.
We are uncertain about forecast snowfall amounts.

Avalanche Summary

On Monday, A size 3 skier remote avalanche was reported that occurred in the Qua area near Nelson.

Several Mountain Information Network posts describe human-triggered slab avalanches failing on crusts and/or surface hoar layers down roughly 30 cm.

Looking forward, weak layers described in the snowpack summary are likely to remain sensitive as they are loaded with new snow.

Snowpack Summary

An additional 10 to 15 cm of snow brings storm snow totals to roughly 30 to 35 cm. This new snow has buried a complex upper snowpack. This region is highly variable with similar weak layers that vary widely in depth and distribution:

On February 13th a surface hoar layer and/or a crust on solar aspects was buried.
On February 7th a surface hoar layer/crust layer (depending on aspect) was buried.
On January 26th, a surface hoar/crust layer sitting on a facet layer was buried and is down 60 to 80 cm.

This weak snowpack structure will continue to produce avalanches as new snow loads it.

The mid and lower snowpack remain well settled.

Weather Summary

Monday Night
Mostly cloudy. 3 to 5 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -5 °C.

Tuesday
Mostly cloudy. 1 to 10 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Wednesday
Mix of sun and clouds. 1 to 3 cm of snow. 10 km/h south ridgetop wind. Treeline temperature -9 °C.

Thursday
Mostly cloudy. 1 to 5 cm of snow. 10 km/h southwest ridgetop wind. Treeline temperature -11 °C.

Terrain and Travel Advice

Storm slabs in motion may step down to deeper layers resulting in large avalanches.
Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.
Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
