Highlights

A skier triggered avalanche in West Bowl (near Lake Louise) indicates that despite the lack of recent natural avalanche activity skier triggered avalanches are still possible. Safe travel and conservative decision making is still required.

    High winds today have created fresh wind slabs on lee terrain. Suspect these slabs are reactive to skier triggering.

  • Persistent Slabs

    60 to 100 cm of recent storm snow lies overtop of basal facets. Natural avalanche activity has subsided. Whoomphing in the alpine indicate that the snowpack is still reactive to skier triggering and the potential for full depth releases still exist.
