Regions

South Coast.

The recent storm snow may need a bit more time to bond to the snowpack.

Avalanche Summary

Although reports are limited, no new avalanches were observed on Tuesday.

Snowpack Summary

Around 10 to 20 cm of snow fell on Wednesday. This snow may not bond well to underlying surfaces, particularly in the north of the region where the snow may have fallen on a weak layer of feathery surface hoar.Deeper, about 60 cm of recent snow sits on a thick melt-freeze crust. Reports indicate that the snow is bonding well to the crust in certain areas but may be slower to bond in other areas.The middle and lower snowpack are well-settled. Snow depths increase substantially with higher elevations. Expect to find about 200 cm at treeline elevations.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
