Weather Forecast

Monday will be flurries yet models are not agreeing on the snow amounts with predictions of 0-12cm. Alpine temperatures will be -4 C and increasing SW winds. Click here for the Avalanche Canada mountain weather forecast.

Snowpack Summary

10-15cm of low density snow sits over a firm mid pack consisting mainly of facets. The primary layer of concern continues to be the October 25 crust 0-40cm off the ground. This crust is most prevalent in deeper snowpack areas predominately on N-NE lee features. Faceting above and below this layer continue to weaken the lower snowpack.

Avalanche Summary

No patrol Sunday and nothing new reported. Saturday's Hy 93 patrol reported no new avalanche activity. No natural activity has been observed in the last 5 days.

Confidence

Forecast snowfall amounts are uncertain on Tuesday

Avalanche Problems

Deep Persistent Slabs

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.
Watch for whumpfing, hollow sounds, and shooting cracks.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible
