Avalanche Summary

There have been no recent reports of avalanche activity. If you're out we'd love it if you would submit what you're seeing to the Mountain Information Network.

Snowpack Summary

15-30 cm of new snow accumulated over the past week. This likely sits over a widespread, supportive melt-freeze crust from early April. Surface hoar and facets were previously observed on this crust on high north aspects. At lower elevations, ongoing warm weather has been promoting isothermal snowpack conditions and melting the snowpack away.

Avalanche Problems

Wind Slabs

Recent strong winds are suspected to have built fresh wind lsabs in the lee of terrain features.

  • Look for signs of instability like whumphing, shooting cracks, and recent avalanches.
  • Avoid recently wind loaded features, especially if they are being warmed by the sun.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
