Storm slabs have been reactive in the region.
Start with conservative terrain and watch for signs of instability.
New snow and wind will continue building slabs overnight and into Monday. These slabs will be more reactive in areas where the storm snow is resting on a layer of surface hoar.
Jan 3
Naturally triggered storm slabs up to size 3 were observed in the Selkirks.
Storm slabs were reactive to ski cuts in the Monashees and Selkirks, producing several size 1 to 1.5 avalanches.
Jan 1
In the Monashees, a skier triggered a size 1.5 wind slab on a wind-loaded roll in the alpine.
Dec 31
Several size 1 to 2 storm slabs were triggered with explosive control in the alpine.
Approximately 20–40 cm of recent storm snow may be resting on a weak layer of surface hoar in many areas. An additional 5–15 cm of snow is expected by Monday mid-morning, accompanied by southwesterly winds.
The prominent mid-December crust is buried up to 130cm deep, and is present up to 2300 m. Triggering this layer is considered unlikely, except with large loads or in thin snowpack areas.
