Deryl Kelly,
If you must travel in the Back Country: keep your objectives short, and close to home. Even a small injury will have serious consequences with the present temperatures.
Ice climbers be very leery of any brittle, overhead features.
Summary
Weather Forecast
Coldest recorded temps (so far;): Maligne, -40.1; Parkers Ridge, -34.9
My limited meteorological experience tells me, it's really cold; and not looking to be tolerable, at least until the end of the week.
Wednesday: Sunny with cloudy periods. Alpine temperature: High -24 °C. Ridge wind northeast: 10 km/h.
Snowpack Summary
The cold has deeply penetrated the snowpack, promoting profound facetting in the upper 40cm. This will slow any slab development on the recent storm snow. The mid-pack has remained strong but, will loose strength over time with the prolonged arctic influence, especially where shallow.Â
Avalanche Summary
No recent avalanche activity observed or reported.
Confidence
Due to the number of field observations
Problems
Wind Slabs
Wind speeds have remained light with only occasional transport speeds recorded over the past few days. Watch for areas of localized wind effect in the ALP and exposed TL features.
- Be cautious as you transition into wind affected terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.

Cornices
Cold temperatures can make cornices brittle. Keep a healthy distance away both when traveling below, or near corniced features.
- Avoid travel on slopes that are exposed to cornices overhead.
- Give cornices a wide berth when traveling on ridges.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine.
