Regions: Birkenhead, Duffey, Homathko, Sea To Sky, South Chilcotin, South Coast Inland, Stein, Taseko.

Human-triggered persistent slab avalanches remain a concern in areas not capped by a thick surface crust.

Confidence

Moderate

Avalanche Summary

No recent avalanches have been reported in the region.

If you are heading into the backcountry please consider posting your observations to the Mountain Information Network. We read every report!

Snowpack Summary

A dusting of snow overlies a thick crust capping a moist upper snowpack on all but direct north aspects above 1900 m, where dry settled snow can be found.

A significant crust/facet layer is buried 60 to 170 cm deep. It was reactive to human triggering over a week ago and continues to be reactive in snow pit tests. Human-triggering remains a concern on northerly aspects above 1800 m.

Below the crust, the snowpack is well settled.

Weather Summary

Tuesday Night

Partly cloudy. 10 km/h south ridgetop wind. Treeline temperature -8 °C.

Wednesday

Mostly cloudy with up to 5 cm of snow. 30 km/h south ridgetop wind. Treeline temperature -4 °C with freezing level reaching 1500 m.

Thursday

A mix of sun and cloud. 10 km/h south ridgetop wind. Treeline temperature -2 °C with freezing level reaching 1700 m.

Friday

Mostly sunny with a few clouds. 10 km/h northwest ridgetop wind. Treeline temperature -4 °C with freezing level reaching 1500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Conditions may have improved, but be mindful that deep instabilities are still present.
  • Use caution on large alpine slopes, especially around thin areas that may propagate to deeper instabilities.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Avalanche Problems

Persistent Slabs

Concern remains for human-triggering the persistent weak layer on sheltered north aspects above 1800 m. If triggered, avalanches will be large and destructive. Avoid shallow snowpack areas where triggering is more likely.

Aspects: North, North East, North West.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3.5
