Regions

Cariboos, Blue River, Clearwater, McBride, Premier, Quesnel, Clemina, North Monashee.

Avalanche danger will increase throughout the day as new snow accumulates.

If you see 30 cm of new snow, treat the danger as HIGH.

Confidence

Moderate

Avalanche Summary

New snow and wind are forecast which will lead to an increase in avalanche size and likelihood this weekend. Both storm slabs and persistent slabs are expected.

On Thursday, there was a size 1.5 natural cornice failure near Blue River.

Snowpack Summary

10 to 25 cm of new storm snow is expected by the end of the day Saturday, adding to 10 to 15 cm on a melt-freeze crust that extends to ridge top on all aspects, except northerly slopes above 1700 m.

A weak layer formed in February, consisting of facets, surface hoar, or a crust, is found 30 to 60 cm deep. Additional weak layers formed in January are present within the upper 100 cm of snow, including faceted snow, crusts on south-facing slopes, and surface hoar in shaded terrain.

The mid and lower snowpack is generally well-settled and strong.

Weather Summary

Friday Night

Mostly cloudy with 0 to 2 cm of snow. 30 to 50 km/h south ridgetop wind. Treeline temperature -5 °C.

Saturday

Cloudy with 10 to 25 cm of snow. 30 to 60 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Sunday

Cloudy with 20 to 45 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1300 m.

Monday

A mix of sun and cloud with 5 to 10 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Terrain and Travel Advice

  • Be mindful that deep instabilities are still present in the snowpack.
  • Uncertainty is best managed through conservative terrain choices.
  • Watch for fresh storm slabs building throughout the day.
  • Storm slab size and sensitivity to triggering will likely increase through the day.

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.
