Wind slabs may be found in the immediate lee of peaks and ridges, and may be poorly bonded to the underlying crust.

Problèmes avalancheux
Confidence
Moderate
- We are uncertain about alpine conditions due to limited field observations.
Avalanche Summary
Very limited avalanche activity was reported since last week. A few small (size 1) dry loose avalanches were reactive to riders over the weekend, and one natural size 2 wind slab was observed on a north-facing slope in the Rockies.
Snowpack Summary
Spring flurries are creating variable accumulations, with 10 to 40 cm of low-density snow in sheltered areas.
A thick crust is buried 30 to 70 cm deep, but may remain exposed in wind-scoured alpine terrain. It extends up to at least 2000 m in the Rockies and 2300 m in the North Thompson.
Below the crust, the snowpack is strong and well bonded.

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- Investigate the bond of the recent snow before committing to your line.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
