Snowpack Summary

As we begin our forecasting season, we are working with limited information from the field. Recent reports from Hudson Bay Mountain suggest an overall shallow snowpack with approximately 20cm of recent storm snow sitting on a crust that formed earlier in the month. This interface was found to be faceted and produced hard but sudden shears while testing. The recent storm snow has also likely been redistributed into locally deep slabs on lee slopes at alpine elevations. Check the bond of the snowpack at this level and take a cautious approach.

Problems

Storm Slabs

An icon showing Storm Slabs
New snow is building up over a potentially weak old surface interface. Changing winds may leave wind slabs on a variety of slopes.
Be cautious as you transition into wind affected terrain.>Caution around convexities or areas with a thin or variable snowpack.>Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.>

Aspects: All aspects.

Elevations: Alpine, Treeline.
