Regions: Kananaskis.

Our deep layers are going to be with us for a long time yet. With no significant weather coming our way, we expect the hazard to flatline for the next while.

Confidence

Good

Weather Forecast

For tomorrow: Cloudy, alpine high of -7, no snow, moderate winds SW.

Avalanche Summary

Nothing of note here

Snowpack Summary

Not much change in the last 24hrs. Slightly more wind effect today, but not enough to be a concern just yet. To add to the list of crusts, a sun crust was noted today on south aspects above 2200m. How this crust is distributed is unknown right now, but it is on the radar. Stability tests today at treeline had mostly hard results, which is encouraging, but still not a promise of a solid snowpack. Snow depths at 2200m were 60cm's, with the Nov 6 crust on average 40cm's down. The basal snowpack is depth hoar.

Avalanche Problems

Deep Persistent Slabs

We are relying on the midpack to give strength to the snowpack. Where the midpack is thin, we can expect the deeper layers to be easily triggered.
Be aware of thin areas that may propogate to deeper instabilites.>Avoid cross loaded slopes at or above treeline.>

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 4
