Kootenay Boundary

Persistent slabs may be found in the Rossland Range. Check the Forecast Details tab for more information.

Tuesday: Moderate N winds. Alpine temperature near -4. No precipitation. Wednesday: Light W winds. Alpine temperature near -2. No precipitation.Thursday: Light S winds. Alpine temperature near -1. No precipitation.

Small skier-triggered wind slabs and loose moist avalanches have been reported.

Fair - Timing or intensity of solar radiation is uncertain

Wind slabs may be found behind terrain breaks such as ridges, ribs and gully walls. Slopes receiving direct sun may now swing between exhibiting moist snow and a frozen sun crust. 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, where an avalanche a week ago, snowpack test results and a whumpf on Sunday demonstrate its potential reactivity, especially from 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 deep avalanche on this layer.
