Assess for storm slabs and unstable snow before committing to steep or high-consequence terrain.

Avalanche Summary

Sunday: A large (size 2) avalanche was observed in the Hudson Bay Mtn area out of steep east-facing alpine terrain.

Saturday: A small (size 1) skier-triggered avalanche was triggered below treeline, and several large (size 2) naturally-triggered avalanches were observed in the alpine in the mountains northeast of Hazelton.

Friday: There were reports of small (size 1) skier-triggered avalanches on north-facing treeline slopes in the Hankin-Evelyn area.

Snowpack Summary

Except for high alpine elevations where some dry snow may still be found, the upper snowpack is moist or wet due to warm temperatures and rain.

Storm snow amounts over the last week have varied across the region. The current storm slab is 15-30 cm thick and is made up of dense, moist or wet snow. On north and east faces these slabs may be thicker due to recent winds. The storm snow may be poorly bonded to a crust formed in early January that extends up to treeline elevations.

Two deeper surface hoar layers exist. These layers have become dormant and unlikely to trigger.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Loose avalanches may start small but they can grow and push you into dangerous terrain.
