    Sluffing can entrain enough volume to become a significant hazard to Climbers, especially in confined space and terrain traps

Snowpack Summary

The shallow snowpack areas will be faceting and loosing support underfoot though much of the forecast region due to the sustained cold temps. Windslabs and wind effect in exposed areas. The fervent hunter may find up to 10-20cm of soft snow found in sheltered S and W pitches. This sits over the Nov crust and is supportive to skis on solar aspects.

Avalanche Summary

Several loose dry avalanches in the alpine from steep terrain on a variety of aspects

Confidence

Intensity of incoming weather systems is uncertain on Tuesday

Weather Forecast

An upper level low over the west coast is forcing a western zonal flow across BC; means high level west winds will drag moisture across the Interior. This will lead with a desperately wanted rise in the daily average temperature and freezing levels through the region. Snowfall forecasted for the coming week.
