Observations have been limited. Please consider sharing your observations through the Mountain Information Network.
Snowpack Summary
By mid day on the 22nd up to 10 cm of new snow may have fallen. This new snow will be accompanied by strong southerly winds forming deeper deposits on northerly aspects. This new snow will fall on an already heavily wind affected upper pack.
The crust from early December is now buried 20 to 40 cm. In some areas, large surface hoar crystals are found at this interface. We are trying to track this surface hoard distribution across the region - most recently, the layer was reactive to skiers in the Ningunsaw area.
