Roughly 50 cm of recent low-density snow continues to be redistributed by northerly winds at upper elevations.
The new snow is poorly bonded in areas to the underlying snowpack, which consists of a variety of firm, previously wind-affected surfaces and crusts. In sheltered terrain at lower elevations, the new snow sits on large surface hoar and a sun crust on solar aspects.
The lower snowpack is generally well settled and bonding well.
At treeline the snowpack depth is roughly 200 cm.
Cold arctic air continues to blanket Southwest BC until Friday when a warm and wet storm begins to move inland.
