Avalanche danger will gradually decrease as a result of a clearing and cooling trend in the coming days.

Avalanche Summary
Expect avalanche activity to taper in the next few days as the temperature begins to cool off and the storm snow begins to slowly bond.
Snowpack Summary
The latest storm Friday night and Saturday was quite warm where it rained to the 1500 m elevation and perhaps above. This has resulted in moist or wet surface snow.At the highest elevations, an additional 40-60 cm of recent snow may not be bonding well to underlying surfaces. This is particularly the case in the north of the region near Squamish, where the snow may be sitting on a weak layer of feathery surface hoar. Deeper, about 60-90 cm of recent snow sits on a thick melt-freeze crust. Reports indicate that the snow is bonding well to the crust.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.
