Wednesday: Light W winds. Alpine temperature near -1. It may warm up to 0 in the afternoon, especially on sunny alpine/treeline slopes. No precipitation.Thursday: Moderate SW winds. Alpine temperature near -2, possibly warming to 0 in the alpine while remaining cooler in the valley. Very light snow starting in the evening.Friday: Light winds. Alpine temperature near -6. Very light precipitation.

Small loose dry avalanches have been reported.

Forecast alpine warming and direct sun may lead to a loose moist snow surface. Wind slabs may be found in isolated areas behind terrain breaks such as ridges, ribs and gully walls. Loose dry snow is sluffing in sheltered terrain. A generally settled upper snowpack overlies the late November surface hoar, buried down 115-130 cm. This layer seems particularly reactive in the Rossland Range, in rocky, thin snowpack areas. A deeply buried crust/facet layer near the base of the snowpack is considered dormant. Although unlikely, there is a lingering possibility of triggering a persistent slab in isolated areas.
