Cariboos, North Rockies, McBride, Quesnel, Sugarbowl, Kakwa, McGregor, Pine Pass, Renshaw, Robson, Tumbler.

While the likelihood of triggering avalanches may be decreasing, the consequences if you do remain very high.

Avalanche Summary

No recent avalanche activity has been reported in the region.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

Roughly 40 to 60 cm of new snow continues to settle and bond over a weak layer buried just before Christmas. This layer consists of sugary faceted grains and/or small surface hoar.

The mid and lower snowpack generally remains weak and facetted, with a number of weak layers present. A layer of particular concern that was buried in November, consists of weak facets, surface hoar, and/or a thin crust, and is roughly 100 to 150 cm down from the surface.

Snowpack depths are roughly 150 to 175 cm at treeline.

Weather Summary

Sunday night

Mainly cloudy, with no precipitation. Light southwest winds. -5 to -10 C at treeline.

Monday

A mix of sun and cloud, no precipitation. Light to moderate southwest winds. -5 to -10 C at treeline.

Tuesday

A mix of sun and cloud, no precipitation. Light to moderate southerly winds. -5 C at treeline.

Wednesday

Mainly cloudy, with no precipitation. Moderate to strong southerly winds. -5 to -10 C at treeline.

Terrain and Travel Advice

  • Keep in mind that human triggering potential persists as natural avalanching tapers off.
  • Be especially cautious near rock outcroppings, on steep convexities and anywhere the snowpack feels thinner than average.
  • Choose simple, low-angle, well supported terrain without convexities.

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.
