Avalanche Canada is warning of dangerous conditions in the region that includes Cranbrook, Kimberley, Creston, and the Columbia Valley.
Avalanche Canada says the risk of snow slides in the Purcells Friday is "moderate" at the ground levels of the backcountry while increasing to "considerable" at mid-and-high elevations.
By Saturday, however, this will again rise to "high" at the alpine in the region.
They say wind slabs are widespread across the Purcells with an 80-120 cm deep weak layer of snow present in many areas.
Avalanche Canada is reporting numerous snow slides this week and believes that more could come this weekend.
A "very large" size 3.5 avalanche was triggered on Tuesday in the northern portion of the region, while a group of skiers had a close call last weekend near Cranbrook. More details on the second incident here.
