    Small pockets of wind slabs may exist in steep, wind-loaded terrain features at higher elevations. Watch for cross-loaded features.

Avalanche Summary

On Friday near Kispiox, wind slabs were reported to be small and hard to trigger along ridgetops and steep entrances.

Several size 2 to 2.5 (large) natural wind slab avalanches were reported in the alpine, occurring more than 3 days ago.

Otherwise, there has been very limited recent avalanche activity.

If you go into the backcountry this weekend, consider submitting a MIN report.

Confidence

High

Snowpack Summary

5 to 10 cm of new snow redistributed by recent winds overlies previously well-settled or wind-affected firm surfaces which may have a layer of weak, feathery crystals on top.

Below this, there is a thick and hard melt-freeze crust that extends into the alpine. The 5 cm of snow buries this crust at lower elevations.

The middle of the snowpack contains old, weak faceted layers and hard crusts, which do not currently present a concern.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
