Regions: Kananaskis.

Snow and wind is forecasted to start tomorrow and continue into Friday. If the storm arrives, expect the hazard to rise by tomorrow evening.

Confidence

Moderate - Intensity of incoming weather systems is uncertain

Weather Forecast

It seems we have a storm working its way towards us. Forecasts vary, but we're expecting anywhere from  10-20cm in the next 48 hours. Strong alpine winds will accompany the storm for its entire length. Treeline elevations will have gusts into the moderate (about 40km/hr) range. Temps will be steady at about -5.

Avalanche Summary

Only some minor sluffing and spindrift was noted today.

Snowpack Summary

On average we've had 5cm of new snow in the last 24hrs. Alpine winds blew most of it around, but probably didn't form much of a wind slab just yet. It did cause some minor sluffing though. The crusts within the snow pack are very evident when traveling. The first is only down 5-10cm and the Oct 26 in basically on, or near the ground. It is thick and still intact.

Avalanche Problems

Deep Persistent Slabs

This is still our main concern at the moment. We are having some difficulty determining the max elevation because of difficult travel. Regardless, we do know it is widespread below 2200m and will break down and become touchier as time passes.
Carry avalanche safety equipment on ice climbs in avalanche terrain.Be careful with wind loaded pockets while approaching and climbing ice routes.Avoid freshly wind loaded features.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible
