Points saillants

Forecast light snowfall will continue to improve ski conditions but is not expected to increase the hazard. Early season conditions persist, the snowpack varies dramatically with aspect and elevation - please factor this into your decision making.

Weather Forecast

We are into a relatively benign weather pattern for this week.  A weak front sliding down from the North will bring light snowfalls to the area today, and possibly Wednesday, as it nudges against a ridge of high pressure which continues to build over Southern BC.

Snowpack Summary

Up to 30 cm of new snow since Dec. 10th was redistributed into fresh storm slabs by light-mod SW-NW winds. 3 buried crusts exist; two from early December are widespread below tree-line, and one from mid November at all elevations which was scoured clean in exposed areas prior to last weeks storm - these have not produced any recent avalanches.

Avalanche Summary

No new avalanche activity has been observed or reported.
