Kootenay Boundary, South Columbia, Bonnington, Grohman, Norns, Rossland, South Okanagan, Badshot-Battle, Central Selkirk, Goat, Gold, North Okanagan, Valhalla, Whatshan.

Fresh snowfall is gradually accumulating over a supportive crust.

Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

Roughly 10 to 30 cm of dry snow sits atop a widespread, hard crust. In general, the crust is strong and thick enough to be supportive to travel on.

In the mid and lower snowpack, various weak layers persist in areas, however, triggering any of these layers is unlikely given the supportive crust above.

Weather Summary

Monday Night

Cloudy with up to 10 cm of snow, south alpine winds 10 to 30 km/h, treeline temperature -5 °C.

Tuesday

Cloudy with 2 to 8 cm of snow, southwest alpine winds 10 to 30 km/h, treeline temperature -5 °C.

Wednesday

Mostly cloudy with up to 8 cm of snow, south alpine winds 10 to 30 km/h, treeline temperature -5 °C.

Thursday

Mostly cloudy with trace snow amounts, south alpine winds 0 to 20 km/h, treeline temperature -7 °C.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Wind slabs may be poorly bonded to the underlying crust.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
