Regions

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

Storm snow continues to stack up over a weak underlying surface.

The best and safest riding will exist in lower-angled, sheltered terrain.

Confidence

Moderate

Avalanche Summary

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

Storm snow has stacked up in the past week, and could be reaching a tipping point for reactive slab avalanches. Learn more in our recent conditions update.

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.

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Be especially cautious as you transition into wind-affected terrain.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • 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.
