Regions

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

Another round of snow, wind, and warm temperatures!

Natural avalanches are expected - avoid avalanche terrain and overhead hazard. Weak layers may produce full path avalanches.

Confidence

Moderate

Avalanche Summary

We expect widespread natural avalanche activity to occur with the warm temperatures, wind and rain. Slabs may run within the recent storm snow, or on buried weak layers.

Snowpack Summary

Storm totals continue to rise! Another 20-50 cm of new snow adds to the 50-80 cm of rapidly settling snow from the last week.

Below all of this storm snow, sits a weak layer of surface hoar - most likely in sheltered treeline features. Wide propagating, remotely triggered avalanches have been recently triggered on this layer, which appears to be widespread south of Highway 16 and spottier north of the highway.

Below this is a hard melt-freeze crust from mid-November that may be an issue in the south of the region, especially where combined with facets.

Tuesday
Mostly cloudy. 10 to 25 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1000 m.

Terrain and Travel Advice

  • Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Be aware of the potential for remote triggering and large avalanches due to buried surface hoar.

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.

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.
