Regions

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

Very large persistent slab avalanches continue to be reported.

Triggering is most likely on northerly aspects in the alpine.

Confidence

Low

Avalanche Summary

On Sunday, cornice falls triggered two size 3 persistent slab avalanches on northerly aspects in the alpine near McBride.

Numerous naturally triggered wet loose avalanches up to size 2 were also reported.

On Saturday, a sledder triggered size 2 persistent slab avalanche was reported below an alpine ridgetop near the Clemina Creek. See MIN

NOTE: Observations in this region are currently very limited.

Snowpack Summary

Recent convective snowfall has been highly variable, accumulating over a crust in most areas except shady aspects in the high alpine where soft or wind affected dry snow may be found.

The primary weak layer of concern is a surface hoar, facet, and crust layer from early March, buried 50 to 100 cm deep. While its distribution and sensitivity remain uncertain, it has been highly reactive in the neighbouring Monashee regions.

The lower snowpack is likely strong and bonded in most areas.

Terrain and Travel Advice

  • Cornice failures could trigger large and destructive avalanches.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • In times of uncertainty, conservative terrain choices are our best defense.
  • Triggering deep layers is more likely if the snow surface didn't freeze overnight.

Problems

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.
