Regions

Cariboos, Blue River, Clearwater, McBride, Premier, Quesnel, Clemina.

Investigate the bond of the top snow layer before committing to high consequence terrain.

Confidence

Moderate

Avalanche Summary

No recent avalanche activity has been reported. Looking forward, the most likely areas for riders to trigger avalanches are in lower alpine slopes, where pockets of buried surface hoar may exist under a slab of snow from last weekend.

Observations remain limited in this region. If you head into the backcountry, please consider sharing your observations to the Mountain Information Network (MIN)!

Snowpack Summary

Around 10 to 30 cm of snow overlies a hard melt-freeze crust up to 1300 m and perhaps isolated pockets of surface hoar crystals in wind-sheltered openings at treeline and above. At upper elevations, westerly wind has redistributed surface snow, loading lee terrain features.

There are currently no deeper layers of concern.

Weather Summary

Thursday night

Mostly cloudy. 10 to 30 km/h south ridgetop wind. Treeline temperature -6 °C.

Friday

Cloudy with 0 to 5 cm of snow. 20 to 40 km/h south ridgetop wind. Treeline temperature -7 °C.

Saturday

Cloudy with 5 to 15 cm of snow. 50 to 70 km/h south ridgetop wind. Treeline temperature -5 °C.

Sunday

5 to 10 cm of snow overnight then clearing to a mix of sun and cloud. 20 to 40 km/h west ridgetop wind. Treeline temperature -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Investigate the bond of the recent snow before committing to your line.
  • Carefully evaluate steep lines for wind slabs.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
