Kernpunkte

A bit of a ski quality refresh on North aspects due to 10-15cm at higher elevations. Leave early and end early to avoid solar heating issues . SH

    There have been many cornice failures over the past week, and in isolated events have been enough load to trigger deeper basal layers.

Weather Forecast

Freezing levels to valley bottom Sunday morning and up to 2300-2400m in the afternoon. There will be a mix of sun and cloud, and the possibility of a few cm in the afternoon in alpine regions. Winds will be light from the South West. Freezing levels will start to increase significantly Monday and Tuesday.

Snowpack Summary

5-15 cm's of new snow in the high alpine from a brief storm Friday. Some small, isolated wind slabs up to 30cm's were reported on the Wapta Friday. Firm crusts up to 10cms thick remain intact at most elevations below the new snow surface. The basal facets are laying dormant.  A very large cornice load or isothermal conditions may change this.

Avalanche Summary

No new avalanches were observed today.
