Avalanche Summary

So far this season there has been insufficient snow on the ground to produce avalanches. Watch for high elevation areas where the recent storm delivered enough snow to cover the ground roughness.

Snowpack Summary

Recent storms delivered more rain than snow to the South Coast mountains. As a result there are just thin patches of wet snow around the peaks of the North Shore mountains (20-30 cm deep). We don't have any recent observations from higher peaks in the region, but there's potentially enough snow to produce avalanches in terrain above 1500 m.

Avalanche Problems

Storm Slabs

The highest peaks of the region may have received significant amounts of snow over the past few days. Triggering storm slab avalanches may be possible in these areas.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
