Avalanche Canada
The snowpack is recovering from the latest input of moist snow and rain. Be cautious around steep, convex terrain and freshly loaded features.
Summary
Confidence
Moderate - Uncertainty is due to difficult to forecast freezing levels.

Avalanche Summary
A few small (size 1) wet-loose avalanches were observed on Thursday morning as the rain event began.Â
Snowpack Summary
Wet snow has accumulated at higher elevations and where dry snow prevailed (at the highest elevations), winds have scoured and redistributed the new snow developing slabs and building cornices. Rain and warm temperatures have promoted settlement in the upper snowpack and moist surface snow up to 1900 m. At lower elevations, rain saturated the snowpack.
Rain earlier in the week created a strong and settled snowpack, which is now 250-300 cm deep around the peaks of the North Shore mountains.
Terrain and Travel
- Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
Problems
Storm Slabs
Storm slabs developed at higher elevations where recent snow accumulated and stayed cold. At lower elevations rain saturated the snowpack, however loose wet avalanches may still be triggered in steep and extreme terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
