    Warming and direct sun may weaken surface snow layers, especially on steep, sun-warmed slopes.

Confidence

Fair - Timing or intensity of solar radiation is uncertain

Avalanche Summary

Small loose dry avalanches have been reported.

Snowpack Summary

Surface layers may become weak with solar radiation and forecast warming temperatures this week. A generally settled upper snowpack overlies two or more buried crusts. The December crust is found 70-140 cm below the surface and the November crust/facet layer is near the base of the snowpack. Recent snowpack tests have shown little reactivity on these layers, apart from in the Flathead Range near Fernie, where there is a lingering possibility of triggering a deep avalanche in specific thin, rocky snowpack areas.
