Avalanche Summary

Reports from Monday include a few small 10-20cm deep naturally releasing storm and wind slabs north of Stewart, as well as some sloughing on isolated steep slopes below treeline. We have had no reports from popular recreational spots in the region. Let us know what you are seeing at forecaster@avalanche.ca.

Snowpack Summary

As we begin our forecasting season, we are working with limited information from the field. Early reports suggest there's enough snow for avalanches at alpine and some treeline elevations. Recent snow has likely been redistributed by gusty and variable winds into slabs on lee slopes at alpine and treeline elevations. This snow may overlie a weak old snow surface (surface hoar, facets and/or a crust) which developed during November's dry spell. Check the bond of the snowpack at this level and take a cautious approach as new snow builds deeper above this layer.

Problems

Storm Slabs

An icon showing Storm Slabs
Recent heavy snowfall with fluctuating temperature and wind likely resulted in weak storm slabs.
Be cautious as you transition into wind affected terrain.>Avoid travelling in areas that have been reverse loaded by winds.>Avoid convexities or areas with a thin or variable snowpack.>

Aspects: All aspects.

Elevations: Alpine, Treeline.
