Regions

Cariboos, North Rockies, Blue River, Clearwater, McBride, Premier, Quesnel, Sugarbowl, Kakwa, McGregor, Pine Pass, Renshaw, Robson.

Assess for the bond of last weekend's snow before committing to high consequence terrain.

Confidence

Moderate

Avalanche Summary

A few large (size 2) storm slab avalanches were observed in the southern Cariboos on Sunday, starting in very steep alpine terrain on a northeast aspect. The avalanches likely released within the weekend's storm snow. It may remain possible for riders to trigger similar avalanches.

Observations remain limited in this region. If you head into the backcountry, please post to the Mountain Information Network.

Snowpack Summary

Warm air from the weekend means a hard melt-freeze crust is found on or near the snow surface up to around 1300 m. At higher elevations, around 10 to 30 cm of snow accumulated over the weekend. This storm snow may sit on a hard crust and/or feathery surface hoar crystals. Recent wind from southwest to northwest directions means that deeper deposits may be found in lee terrain features in wind-exposed terrain.

There are currently no deeper layers of concern.

Weather Summary

Monday Night

Mostly cloudy with trace amounts of snow possible. 10 to 30 km/h northwest ridgetop wind. Treeline temperature -10 °C.

Tuesday

Mostly cloudy with trace amounts of snow possible. 10 to 30 km/h west ridgetop wind. Treeline temperature -5 °C.

Wednesday

Cloudy with 5 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Thursday

Cloudy with 5 cm of snow. 20 to 40 km/h south ridgetop wind. Treeline temperature -4 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Be careful as you transition into wind-affected terrain.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
