In sintesi

New snow, wind and warm temperature is a recipe for elevated avalanche hazard.

Treat the hazard as high if you are moving through terrain with more than 40 cm of new snow.

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 100 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 100-130 cm. 200-300 cm around Stewart. Snowpack depth gradually thins as elevation decreases to be 50 cm at valley bottoms.
