Avalanche Summary

On Monday, a natural avalanche cycle up to size 3 was reported. With more snow and strong forecast winds, you can expect this to be the story on Tuesday.

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.
