Regions: Kananaskis.

Cooling temps will help lock in the snowpack tomorrow. We are expecting a dusting of snow tonight. We'll see if its enough to get good dust on crust skiing.

Weather Forecast

Cooler temps and cloud cover tomorrow, and even a chance of some light snow. The daytime high will be just below 0C with the freezing level at 1800m. A short bit of snow is expected to come through tonight, but only leave 6cm. Alpine winds will be moderate from the SE.

Avalanche Summary

Nothing new today.

Snowpack Summary

Valley bottom snow tends to be refrozen, isothermic snow up to 2300m, all aspects. Above that, the true north aspects have dry snow and crusts on the remaining aspects. Windslabs are still present in north facing alpine terrain.

Avalanche Problems

Wind Slabs

These are lingering on true north aspects at the moment. If we do get snow tonight/tomorrow, expect fresh windslabs. They'll be small, but sitting on a slippery crust.
Avoid freshly wind loaded features.

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

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2

Deep Persistent Slabs

Despite the cooling. this is still on our minds. By day 2 of the cooling we'll become more comfortable with this layer, but for now its still on the radar.
Be aware of thin areas that may propogate to deeper instabilites.Be aware of the potential for full depth avalanches due to deeply buried weak layers.Be aware of the potential for wide propagations due to the presence of hard windslabs.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 2 - 3
