Regions
South Coast.
Snowfall accumulation will increase through the day. If totals exceed 25cm, avalanche hazard will be HIGH.
Confidence
Moderate - Intensity of incoming weather systems is 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
The snowpack has been below threshold depth for avalanches in the North Shore mountains and terrain below 1500m elevation. Incoming snow is not expected to bond well with a recently formed crust.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.
