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

New snow will be prone to isolated wind slab formation in alpine lees, as well as solar-triggered loose avalanches on steep slopes.

Confidence

Low

Avalanche Summary

A couple of large cornice failures were observed last week in high alpine north-facing terrain. These loads notably did not propagate any weak layers on the slopes below.

Snowpack Summary

A bit of new snow falls over widespread crusty surfaces on all but high north-facing alpine terrain, where snow is dry and likely wind affected. There are no deeper concerns at this time.

Weather Summary

Wednesday night

5 to 10 cm of new snow, up to 20 cm near Mt Robson. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1400m.

Thursday

A mix of sun and cloud. 10 to 30 km/h northwest ridgetop wind, easing. Treeline temperature -1 °C. Freezing level 2000m.

Friday

A mix of sun and cloud. 10 to 20 km/h east ridgetop wind. Treeline temperature +1 °C. Freezing level 2200m.

Saturday

A mix of sun and cloud. 20 to 30 km/h south ridgetop wind. Treeline temperature +1 °C. Freezing level 2300m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Brief periods of sun could quickly initiate natural avalanche activity.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Wind Slabs

Small wind slabs are possible where wind has deposited sufficient snow into lee terrain features at upper elevations. Wind slabs may be especially reactive where they sit over a crust.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5

Loose Dry

Cold dry snow will be especially sensitive to seeing the sun for the first time. Expect small loose avalanches on steep slopes if the sun comes out.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
