Snowpack Summary

Alpine areas near Squamish have the most snow, with a suspected 70 cm of settled snow on the ground. In these areas there may be a crust lower in the snowpack, however it is now suspected to be well bonded to the overlying storm snow. There is generally insufficient snow for avalanches below 1500 m.

Problems

Loose Wet

An icon showing Loose Wet
Warm temperatures and strong sunshine will destabillize surface snow and promote loose wet avalanche activity on sun-exposed slopes on Wednesday. Loose wet slides may occur naturally or with a human trigger.
Be aware that low-angle December sun tends to focus radiation on steeper slopes.Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: South East, South, South West, West.
