Avalanche Forecast
Regions: Coquihalla, Manning, Skagit.
Storm slabs sit over a weak layer and are easily triggerable by riders. Stick to simple, low angle terrain and avoid overhead hazard.
Confidence
Moderate
Avalanche Summary
No recent avalanches have been reported. Snowpack tests in this MIN report from Zoa produced easy shears below the storm snow on Saturday. Storm slabs will likely be triggerable by riders on Sunday.
Snowpack Summary
Light snowfall continues. 25 to 50 cm of new snow has accumulated since Friday. Near ridgetops, moderate to strong southwest wind has loaded new snow into leeward terrain features. The new snow is not expected to bond well to underlying layers including a hard crust, facets and/or surface hoar.
The mid and lower snowpack is well-settled and dense with no other layers of concern.
