    The 10 to 20 cm of snowfall from Wednesday will need some time to bond to the snowpack. Deeper, reports suggest that the 60 cm of recent storm snow may not be bonding well to an underlying hard crust.

Snowpack Summary

Around 10 to 20 cm of snow fell on Wednesday. This snow may not bond well to underlying surfaces, particularly in the north of the region where the snow may have fallen on a weak layer of feathery surface hoar.Deeper, about 60 cm of recent snow sits on a thick melt-freeze crust. Reports indicate that the snow is bonding well to the crust in certain areas but may be slower to bond in other areas.The middle and lower snowpack are well-settled. Snow depths increase substantially with higher elevations. Expect to find about 200 cm at treeline elevations.
