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

Uncertainty remains regarding buried weak layers in this region, so careful snowpack and terrain assessment is crucial.

Be extra cautious around cornices and sun-exposed slopes.

Confidence

Moderate

Avalanche Summary

Reports have been limited in this region, but weekend observations indicate a widespread cycle of large persistent slab avalanches during last weekend's warm-up. The status of this problem remains uncertain, but it likely persists on north-facing terrain at treeline and alpine elevations.

Snowpack Summary

Expect wet and moist surfaces on sun-exposed slopes. 10 to 20 cm of wind-affected dry snow exists at high elevations, sitting over a melt-freeze crust. Below this, the upper snowpack remains moist or wet.

Several persistent weak layers from January, February, and March can be found between 1 and 2 m deep across the region.

At lower elevations, the rain-saturated snowpack tapers quickly with elevation.

Weather Summary

Wednesday Night

Partly cloudy. 20 km/h northwest ridgetop wind. Treeline temperature -4 °C.

Thursday

Mostly sunny. 20 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1700 m.

Friday

Sunny. 10 km/h southeast ridgetop wind. Treeline temperature +2 °C. Freezing level 2000 m.

Saturday

Mix of sun and cloud. 30 km/h south ridgetop wind. Treeline temperature +3 °C. Freezing level 2300 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Make observations and continually assess conditions as you travel.
  • Be aware of the potential for large avalanches due to buried weak layers.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Persistent Slabs

Weak layers remain a concern, especially in north-facing terrain & where snowpack depth is variable. They have recently produced large avalanches and may be triggered by cornices or humans in steep, shallow terrain at upper elevations.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely

Expected Size: 2 - 3.5

Loose Wet

Periods of sun could trigger wet loose avalanches.

Aspects: South East, South, South West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
