Crowsnest North

Avoid avalanche terrain.
Heavy snowfall and wind have likely built dangerous storm slabs.

Up to 15 cm of snow has been blown around by strong winds and sits on a widespread melt–freeze crust, which is likely everywhere except high-alpine terrain.

A mid-November crust is buried 50 to 100 cm deep. Beneath it, the snowpack contains several additional crusts, and in some locations, a weak, sugary facet layer near the ground.

At treeline, snow depths range from roughly 50 to 100 cm, tapering off quickly at lower elevations.

No new avalanches have been reported this week. However, information is limited.
It's expected that natural avalanches will occur on Wednesday following the intense storm.

• Avoid avalanche terrain during periods of heavy snowfall.
• Be aware of the potential for large avalanches due to buried weak layers.
• Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
