    Warm temperatures may keep storm slab reactive.

Snowpack Summary

25-30cm HST continues to be redistributed in the Icefields by moderate S/SW winds, creating a reactive windslab in open areas at treeline and above. Soft storm slab found below treeline may be reactive to light loads. Generally, the mid-pack is holding but showing variable support throughout the forecast region as it slowly facets out. HS ranges from 60 to 120cm at treeline in the Icefields. The Bald Hills area has received less storm snow; average HS of ~60cm.

Confidence

Moderate

Avalanche Summary

Significant avalanche cycle on the Icefields Parkway with windslabs dominating the field reports.

Potential for triggering destructive slabs in large features remains a concern.
