Avalanche Summary

New snow is expected to cause an active storm slab avalanche cycle.

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 will add 25 cm to the upper snowpack, making 75 cm of snow that is sitting on a crust from recent high freezing levels and rain.

Spotty 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 to be 50 cm at valley bottoms.

Many early season hazards are just below the surface below treeline.

Terrain and Travel Advice
