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

Weather Forecast

Arctic high pressure system. Cold north and easterly winds with clear skies will remain in place most of the week. For more details: Avalanche Canada's, Mountain Weather Forecast.

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
