Kernpunkte

Snowfall amounts are uncertain, but combined with the ongoing strong winds may load lee terrain enough to increase the danger rating.

    Assume all skiable slopes have this crust, and assess the strength of the interface before jumping into any committing lines. See forecast details for more info on this layer.

Weather Forecast

Ongoing strong SW winds.  Snow flurries will give up to 10cm of new snow by Wednesday. Alpine temperatures will be between -4 C and -8 C. Click here for the Avalanche Canada mountain weather forecast.

Snowpack Summary

Strong SW wind with incoming snow flurries is building fresh windslab. The October 25 crust, sitting 0-40cm off the ground, remains a concern. This crust is most prevalent in deeper snowpack areas - found predominately on N-NE lee features. Faceting above and below this layer continues to weaken the lower snowpack.

Avalanche Summary

The local ski hill triggered two windslabs (one large/size 2) during explosive control work on Sunday.

Confidence
