Regions: Kananaskis.

Warm temps, ongoing wind and flurries are creating new slabs as we speak. Make frequent observations to help paint a complete picture of the snowpack's character.

Confidence

Another 5-8 cm is expected tonight. Unfortunately the cold will make a come back with morning lows somewhere around -20. Winds will be light out of the SW

Avalanche Summary

Snowpack Summary

The Oct and Nov crusts were very apparent in today's field trip. Both layers were ice and buried about 40cm. This area was likely an anomaly during the warm spell, so expect the crust character to be very different elsewhere. In some areas the crusts have completely faceted out. Wind effect is apparent in any open area with soft windslabs being widespread. The snowpack had a distinct "punchy" or "cakey" feeling to it today. Travel is tedious and difficult up to about 2000m.  

Avalanche Problems

Wind Slabs

This includes buried slabs and surface slabs.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Persistent Slabs

Today was the first avalanche observation involving this layer. Put it back on your radar for thing to inspect in the snow.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 2.5
