Regions

Cariboos, North Rockies, Blue River, McBride, Premier, Quesnel, Sugarbowl, Clemina, North Monashee, Kakwa, McGregor, Renshaw, Robson.

Storm slab avalanche activity will increase with the arrival of another load of new snow on Saturday.

Confidence

Moderate

Avalanche Summary

A size 2 avalanche was observed in the Clemina region on Thursday; we suspect it occurred on Tuesday or Wednesday. This avalanche was on a NW aspect at roughly 2000 m elevation. It failed on a layer of surface hoar down 75 cm.

Snowpack Summary

In many areas, over 50 cm of new snow has accumulated since last weekend. Persistent westerly winds during these storms have formed deeper deposits of wind-loaded snow on leeward slopes at higher elevations.

In sheltered terrain, especially near treeline, a preserved surface hoar layer may have been buried 40 to 80 cm below the surface. The distribution of this layer appears to be more widespread south of Highway 16, while it appears more spotty and inconsistent north of the highway.

Snow depths at treeline average 100 to 150 cm and decrease rapidly at lower elevations.

Weather Summary

Friday Night
Cloudy. 2 to 5 cm of snow. 10 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 700 m.

Saturday
Cloudy. 5 to 15 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 1000 m.

Sunday
Mostly cloudy. 5 to 15 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -5 °C. Freezing level 700 m.

Monday
Mostly cloudy. 3 to 25 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 900 m.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Be careful as you transition into wind-affected terrain.
  • Be cautious of buried obstacles, especially below treeline.

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.
