Direct sun and rising freezing levels could weaken the snowpack on southerly aspects.
Minimize your exposure time below cornices and approach shallow rocky areas with caution.
Lingering wind slabs are present in lee areas. These wind slabs may be bonding poorly to the underlying surfaces and be reactive to riders, especially on steep, convex slopes. Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
Solar-induced wet loose avalanches occurred Tuesday on south aspects throughout the region, as conditions were clear and sunny.
Several small avalanches were reported over the last few days near Fernie, including skier-triggered wind slabs on alpine convex rolls, natural cornice falls and loose avalanches from steep terrain.

At upper elevations, recent snow overlies a crust on solar aspects, faceted snow and surface hoar (up to 10 mm) in shaded and wind-sheltered areas. Wind-affected surfaces are also found in exposed areas. At lower elevations, a crust exists on or near the surface.
The mid-snowpack is generally well-settled, but a lingering persistent weak layer has shown some signs of reactivity near Leach Ridge a few days ago. The lower snowpack includes a layer of weak sugary crystals near the ground. This layer has not produced recent avalanche activity. Professionals are still tracking it to watch for signs of it waking up.
The region will be under a building ridge of high pressure, with calm and dry conditions for the next few days.
