Snowpack Summary

30cm of low density snow fell since Saturday in the ice fields area, with less in the Jasper town area. Recent reverse loading may have created wind slabs in the immediate lee in the alpine. This new snow is sitting on a variety of surfaces from wind scoured in the alpine to preserved surface hoar in the protected treeline features. 

Avalanche Summary

No new avalanches observed or reported. No field observations for several days. 

Confidence

Due to the number of field observations

Avalanche Problems

Wind Slabs

Suspect reverse loading and windslabs in the immediate lee from the recent north winds.

  • Keep an eye out for reverse loading created by N-NE winds.
  • Be careful with reverse loaded pockets of wind slab at ridgeline.

Aspects: East, South East, South, South West, West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Loose Dry

Recent low density snow sitting on a variety of surfaces may be a problem in steep terrain such as gully features above ice climbs.

  • Be cautious of sluffing in steep terrain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
