Avalanche Summary

No recent reports of avalanche activity.

Snowpack Summary

Reports suggest there is about one metre of snow at upper treeline elevations. Terrain below treeline is reported to be mostly below threshold for avalanche activity.On the surface 10-35cm of new snow now overlies a generally well settled snowpack. This new snow is likely to exist as a wind slab in exposed high elevation terrain. Rain at lower elevations has continued to saturate what little snow there is. A few crusts can be found deeper in the snowpack 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 exists as a wind slab.

Be cautious as you transition into wind affected terrain.>
