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

Look for changing conditions and signs of instability as you move through the mountains.

Slab size and sensitivity could increase throughout the day.

Confidence

Moderate

Avalanche Summary

Only small dry loose avalanches in steep terrain have been reported in the past couple days.

We expect wind slab avalanches to be rider triggerable in areas that receive more than 10 cm on Friday.

Snowpack Summary

Up to 10 cm of new snow could accumulate throughout Friday. This will add to the 5 to 15 cm that has buried a variety of surfaces including surface hoar  and facets in sheltered terrain, a crust on south and west facing slopes as well as old wind slab on exposed terrain.

The widespread crust buried in early February is near the surface on exposed alpine terrain and down up to 45 cm elsewhere. In many areas this crust has a layer of facets above.

Weather Summary

Thursday Night

Clear skies. 15 to 35 km/h southwest alpine wind. Treeline temperature -4°C.

Friday

Cloudy with up to 10 cm of new snow. 40 to 70 km/h west alpine wind. Treeline temperature -4°C.

Saturday

Cloudy with 5 to 15 cm of new snow. 30 to 60 km/h southwest alpine wind. Treeline temperature -7°C.

Sunday

Cloudy with up to 25 cm of new snow. 30 to 60 km/h northwest alpine wind. Treeline temperature -6°C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Seek out sheltered terrain where new snow hasn't been wind-affected.

Avalanche Problems

Persistent Slabs

As new snow accumulates above this crust layer slab properties could increase, as this happens the size and sensitivity of avalanches on this layer will also increase.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Wind Slabs

New snow and southerly wind has likely formed wind slab near ridge crests. These slabs will be most reactive where they overlie surface hoar or a crust.

Aspects: North, North East, East, West, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 1.5
