There was a natural avalanche cycle that occurred on Wednesday, with many large (size 2 to 3) storm slab avalanches observed. The avalanches were generally 20 to 40 cm deep, on northerly aspects, and within all elevation bands.

More snowfall is expected Thursday night into Friday, with total amounts uncertain but could be upwards of 20 cm or more. This new snow will overly around 30 to 50 cm of recent snow, which sits on variable layers, including wind-affected snow at treeline and alpine elevations, feathery surface hoar crystals in shaded and sheltered areas below treeline, and a melt-freeze crust below 1600 m.The mid-January layer of surface hoar or a crust is buried around 70 cm. The surface hoar is found on shaded and sheltered slopes and is most prominent between 1600 m and 1900 m. The melt-freeze crust is found on south aspects at all elevations.The remainder of the snowpack is generally well-settled. Thin snowpack areas, such as in the east of the region, may find weak and sugary faceted grains near the base of the snowpack.
