Wind slabs may still be triggerable in open lee areas.

Stick to sheltered terrain for the best snow and safest conditions.

    Wind slabs are suspected to be stabilizing but there isn't a lot of info to go off. Individually assess slopes for wind slabs and avoid them if you're finding hollow sounds or shooting cracks.

Avalanche Summary

No new avalanches were reported on Friday or Saturday.

Numerous storm and wind slab avalanches were reported in the Okanagan on Wednesday and Thursday. Rider-triggered avalanches were small and explosive-triggered slabs were large, size 2 to 3.

Snowpack Summary

Alpine terrain is heavily wind-affected, while sheltered areas have 30 cm of settling snow from Wednesday's storm.

A mix of rain and sun crusts is present beneath the recent snow, with reports of isolated surface hoar at these depths in neighbouring regions. So far there hasn't been evidence that these layers are a long-term concern.

Treeline snow depths in the Okanagan region average 110 cm.

Terrain and Travel Advice

  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Investigate the bond of the recent snow before committing to your line.
  • Seek out sheltered terrain where new snow hasn't been affected by wind.
