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.

Problems

Storm Slabs
