Regions

Cariboos, Blue River, Clearwater, McBride, Premier, Quesnel, Sugarbowl.

Wind slabs persist in exposed, high-elevation terrain.

Exercise extra caution during periods of sun or warming, when both cornices and wind slabs may be especially reactive.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.

Avalanche Summary

A few small storm and wind slab avalanches were reported in the region on Wednesday and Thursday. These avalanches occurred predominantly at treeline but one was triggered on a north aspect below treeline.

If you are heading into the backcountry, please share your observations by posting a MIN. Shout out to those who have been submitting.

Snowpack Summary

Recent storm snow has been redistributed by strong southwest winds, forming deeper deposits on north and east facing aspects.

A 10 to 20 cm thick crust, formed during the recent atmospheric river event, is now buried 40 to 60 cm below the surface. The exception is in wind-scoured alpine terrain, where this crust may remain exposed at the surface. It extends up to at least 2000 m in the northern part of the region and 2500 m in the south. Moist snow may still be present beneath this crust.

The early February crust is buried 100 to 160 cm deep and is not currently a concern.

Overall, the remaining snowpack is well settled and generally well bonded.

Weather Summary

Friday Night
Mostly cloudy. 1 to 10 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -7 °C.

Saturday
Mix of sun and clouds. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -8 °C.

Sunday
Mix of sun and clouds. 1 to 5 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Monday
Mix of sun and clouds. 1 to 3 cm of snow. 30 km/h northwest ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Recent strong wind means wind slabs may be found farther downslope than expected.
  • Closely monitor how the new snow is bonding to the old surface.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
