Recent snowfall amounts have been highly variable throughout the region. In some areas (particularly the Monashees where accumulations were reported to be the highest), Treeline and Below Treeline danger ratings may be higher than posted.

Snowpack Summary
Recent storm accumulations have been highly variable throughout the region with roughly 30cm falling in the Selkirks and close to double that in some parts of the Monashees. This new storm slab will increase in reactivity and destructive potential as it deepens or in areas where it has been redistributed and compressed by wind. The new snow covers a variety of old surfaces which include: old wind slabs at higher elevations, melt-freeze crusts on previously sun-exposed slopes and touchy surface hoar in sheltered terrain.In the mid snowpack you may find a layer of surface hoar buried in mid-November ranging from 90cm-130cm in depth. An October crust/facet combo exists near the base of the snowpack. The most likely place you'd trigger this layer is on smooth, planar, high north facing slopes, especially if the snowpack is unusually shallow in that area.These persistent layers are slowly becoming more difficult to trigger. However, they have the potential to cause large and destructive avalanches, and may 'wake-up' with the increased load of the new snow.
