Highlights

We carefully move the avalanche danger ratings to Low at all elevations today. We have taken our time with this, and remind people that the snowpack is not strong. Slight changes in weather will reawaken those facets.

    This problem continues to exist at the base of the snowpack, but triggering is unlikely due to a combination of time, settlement and the bitter cold - all of which have combined to lock up the snowpack. It will reawaken once the weather changes.

Weather Forecast

The arctic high continues to establish itself over BC and Alberta, with temperatures for Monday expected to drop to -26; highs of -20. No snow in the forecast for the week ahead, and light winds from the north.

Snowpack Summary

The snowpack has gained strength over the past few weeks, and the facetted base layer has gone dormant for now (it will wake up again!). Snowpack tests are now producing hard results 20 cm above the ground. The current clear spell has left 10 cm of loose snow sitting on top of a bombproof windslab above treeline, and a thick crust on S & W aspects.

Avalanche Summary

No new avalanches have been observed or reported.
