    Wind slabs may be triggerable at upper elevations where wind has transported dry snow into leeward terrain features. Wind-transported snow has also enlarged cornices recently.

Avalanche Summary

After a stormy and avalanchy week, by Friday reports of avalanche activity were limited to natural wind slabs size 1-1.5 out of north to east aspects in the alpine.

Snowpack Summary

A moist upper snowpack up to 2000 m is refreezing into a crust. In the alpine, the refreeze may be slowed by overlying dry snow; as little as 10 cm near Smithers and and much as 50 cm near the coast. Below 1000 m, the fully rain-soaked snowpack is starting to refreeze.

A variety of previously concerning weak layers buried in January can be found 30 - 80 cm deep. These layers appear to be strengthening and are expected to continue to improve under the current cooling trend.

Weather Summary

Saturday night

Clear. Northwest ridgetop wind 10-20 km/h. Treeline temperature around -12 °C.

Sunday

Sunny. Northwest to northeast ridgetop wind 10-20 km/h. Treeline temperature around -5 °C.

Monday

A mix of sun and cloud. East ridgetop wind 30-40 km/h. Treeline temperature around -6 °C.

Tuesday

A mix of sun and cloud. Southwest ridgetop wind <20 km/h. Treeline temperature around -6 °C.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
