Avalanche Summary

There is no new avalanche activity to report.

Snowpack Summary

Reports suggest there is about 50cm of snow at 1600m in the Duffy Lake area, and about 100cm at the same elevation on the Coquihalla. Terrain below treeline is reported to be mostly below threshold for avalanche activity.Between 15 and 25cm of new snow now overlies a generally well settled snowpack. In exposed high elevation terrain this new snow may exist as a wind slab. Rain at lower elevations has continued to saturate what little snow there is. Closer to the base of the snowpack you may find a few crusts which may have associated facets at higher elevations. Observers are not identifying any of these as cause for concern at this time, although they might be worth exploring.

Problems

Storm Slabs

Variable amounts of new snow are probably gaining strength. The new slab is likely to be most reactive in exposed high elevation terrain where it may exist as a wind slab.

Stay off recent wind loaded areas until the slope has had a chance to stabilize.>

Aspects: All aspects.
