North Columbia

The upper snowpack will weaken throughout the day due to warming and solar radiation, while isolated slabs may persist in steep, high alpine areas.

No recent avalanche activity has been reported.

Despite the low danger rating, the likelihood of triggering an avalanche will increase throughout the day with warming and strong solar radiation expected.

Recent storm snow continues to settle and bond to an underlying crust. At lower elevations and south-facing slopes a surface crust will likely form overnight.

Surface snow will deteriorate and become moist throughout the day with daytime warming and strong solar effects.
