Stale weather to remain through Monday. Forecasts then show a slow increase in temperatures and, sunny skies.
The late winter sun is starting to penetrate the snowpack. Expect some localized instability on steep, solar aspects in the afternoon.
Wind slabs are very prevalent with previous loading in lee features. Sensitivity will vary with local loading and wind patterns.
Shallow snowpack areas and/or large triggers such as cornice failures could trigger this deep layer. The consequences would be severe!
Zonal flow from west to east cycling through the region. A shallow trough holding the last of the moisture moving through, before flow shifts from the Northwest with the approaching ridge on the pacific. Clearing and slight warming by Tuesday/Wednesday.

Variable strength windslab on the surface. Pronounced cornice development on northerly aspects and cross loaded features treeline and above. A supportive mid-pack is bridging the deeper basal facets and depth hoar in some locations.
Average HS at treeline: ~180cm.
Previous public MIN (Mountain Information Network) report of natural size 2, southwest aspect at treeline in the Maligne Valley (thanks @Kaylaolde!!). Field team in Whistler/Portal Creek observed no recent natural avalanche activity; ski-pen 10-15cm.
This area is now open after a seasonal delayed access restriction to protect the Woodland Caribou.
