Snowpack Summary
Moderate south winds have redistributed 40 to 60 cm of recent snow. Rapid settlement has been observed at treeline and below. Expect to find deeper deposits on lee slopes, and windward slopes scoured.
This snow overlies a melt-freeze crust and a well-settled mid and lower snowpack to ground.
Snow height ranges from 100 to 150 cm at treeline in the Coquihalla, to 85 to 100 cm near Manning Park.
