The current storm has produced a running total of ~25-30cm of new snow. Southwest winds are blowing new snow into slabs that are likely to be triggered by riders.
The new snow and wind continue to create dangerous avalanche conditions. Careful assessment is required for riders and climbers.
Expect intermittent road closures for avalanche control from Parkers Ridge through to Coleman Creek. Check for updates on https://511.alberta.ca/
The current storm has produced a running total of ~25-30cm of new snow. Southwest winds are blowing new snow into slabs that are likely to be triggered by riders.
Warm temperatures may keep storm slab reactive.
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.
Significant avalanche cycle on the Icefields Parkway with windslabs dominating the field reports.
Potential for triggering destructive slabs in large features remains a concern.
