Continually assess conditions as you travel and watch out for isolated (wind) slabs.
Confidence
Moderate - Due to the number of field observations

Avalanche Summary
Only minor loose wet Size 1 natural avalanches were observed yesterday in the North Shore mountains.
Snowpack Summary
The North Shore mountains received 10cm of new snow which came in wet and heavy, bonding well to 15 cm of settling snow from Friday's storm. New snow amounts closer to Squamish were almost double (15-20cm). Watch out for small wind slabs on north-facing slopes in the lee of exposed features. Friday's snow buried a variable interface composed of faceted (sugary) snow and old hard wind slabs (especially at higher elevations). Recent reports suggest the snow has bonded fairly well to this interface. The mid and lower snowpack are well settled and stable.
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.
