Regions: Birkenhead, Duffey, South Chilcotin, South Coast Inland, Stein, Taseko.

Evaluate terrain and the snowpack carefully and avoid slopes below ridgetops with deep, freshly wind-loaded pillows of snow.

Confidence

Moderate

Avalanche Summary

There are no recent avalanche reports for this region.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Snowpack Summary

New snowfall has likely buried existing surface hoar that was previously found in wind-sheltered, and sun-sheltered open terrain. A thin melt-freeze crust may exist on south-facing slopes.

Above 1800 m on non-solar slopes, you can find 20 to 40 cm of snow above a thin crust. The crust disappears as you travel higher into the alpine.

Below 1800 m, 15 to 25 cm of snow sits overtop a thicker and more robust crust.

Snow depths at treeline are around 80-90 cm.

Weather Summary

Saturday Night

Snow 5 to 10 cm. 20 to 40 km/h south ridgetop wind. Treeline temperature -1 °C. Freezing level 1200 m.

Sunday

Snow 1 to 2 cm. 10 to 25 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 500 m.

Monday

Snow 1 to 2 cm. 10 to 15 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 500 m.

Tuesday

Becoming clear. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Be aware of the potential for large avalanches due to buried surface hoar.

Avalanche Problems

Wind Slabs

Wind slabs are likely to have formed at higher elevations near ridge top where new snow has been loaded into leeward terrain features.

Aspects: North, North East, East, South East.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Storm Slabs

Buried surface hoar in sheltered terrain is expected to be reactive to human triggers.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
