Highlights

There may be rolling closures for avalanche control on the Icefields Parkway in the Parkers area on Sunday, March 8th. Check for updates on https://511.alberta.ca/

The persistent weak layer remains the primary concern. Avoid steep, open faces, particularly where the snowpack is shallow.

    Recent moderate southwest winds have redistributed the new snow into windslabs at ridgeline and in lee features.

    A 40-80cm slab sitting atop the Jan 24th weak layer of facets & surface hoar has produced several large avalanches in the region this week. This interface is not bonding well and will take time to settle and stabilize.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.
  • We are uncertain about forecast precipitation amounts.

Terrain and Travel Advice

  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Keep in mind that human triggering may persist as natural avalanches taper off.
