Avalanche Forecast
Regions: Coquihalla, Harrison-Fraser, Manning, Sasquatch, Skagit, Stave.
New snow may not be bonding to the cold, wind-affected surfaces below.
Storm slabs and loose dry avalanches will become more likely as snow accumulates throughout the day.
Confidence
Moderate
Avalanche Summary
No recent avalanche activity has been observed.
If you head into the backcountry, please consider submitting a MIN report.
Snowpack Summary
New snow has buried widespread wind-affected snow surfaces at treeline and above. The recent cold and clear weather has likely led to widespread facet and surface hoar development which may prolong the bonding of new snow to the underlying surfaces.
Roughly 100 cm of recent snow sits atop a crust with a generally well-settled and stable lower snowpack.
With recent snowfall lower elevation areas may now be at the threshold for avalanches.
