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

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

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.
Problems
Wind Slabs
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.
Aspects: North, North East, East, South East, North West.
