Points saillants

Clear skies will continue, and the ski quality has improved, but the avalanche hazard is still elevated.

Be aware of what is above you, especially where the wind may be present.

    The new snow may form slab properties over old facets as temperatures warm up.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

A widespread natural avalanche cycle up size 3 has occurred in the last 24-48 hours and is slowly tapering off.

Snowpack Summary

15-40 cm has fallen in this region over the last 72 hours, with the highest amounts along the divide North of Lake Louise. Strong to extreme SW/W winds have created reactive wind slabs at ridgetop and in wind-exposed areas. In some thin areas, there are facets near the base, but overall, the snowpack is stronger than usual.
