Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

A few small (size 1) wind slabs were skier-controlled on Tuesday in the immediate lee terrain at treeline.

Snowpack Summary

Up to 20 cm of new snow falls on a widespread crust from previous warm temperatures and sun up to 2100 m.

A hard crust is buried 30 to 70 cm deep, but may remain exposed in wind-scoured alpine terrain. It extends up to at least 1500 m in the Rockies, and 2000 m in the Cariboos.

Below the crust, the snowpack is strong and well-bonded.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
