Avalanche Summary

A natural avalanche cycle is expected to be ongoing throughout the storm.

If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network). You can share riding conditions, avalanche or snowpack observations, even just a photo or two.

Snowpack Summary

Heavy snowfall continues to add to the upper snowpack. This could add up to 120 cm of snow that is sitting on a crust.

Buried surface hoar crystals may still be present in isolated sheltered areas.

The mid and lower snowpack is expected to be strong, with frozen crusts or dense, settled snow.

At treeline around Terrace we expect a snow depth of 100-150 cm. 200-300 cm around Stewart. Snowpack depth gradually thins as elevation decreases.
