Regions
South Coast.
Avalanche hazard is confined to the high alpine where snow has accumulated. A series of storms this week will hopefully bring snow to lower elevations.
Confidence
Moderate - Forecast snowfall amounts are uncertain

Avalanche Summary
No avalanches have been reported in the region. Please submit any observations you have to the Mountain Information Network here.
Snowpack Summary
On Sunday rain fell around most of the region, with snow beginning to accumulate at the highest elevation areas. This new snow has covered a crust on the old snow surface.Prior to the recent precipitation, the snowpack has been below threshold depth for avalanches in the North Shore mountains and terrain below 1500 m elevation. In alpine areas near Squamish, up to of 70cm settled snow is on the ground. In these areas, a crust is lower in the snowpack, however it is now suspected to be well bonded to the overlying storm snow.
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.
