Natural avalanches unlikely; human-triggered avalanches possible.

Small avalanches in specific areas; or large avalanches in isolated areas.

Dangerous avalanche conditions. Careful snowpack evaluation, cautious route-finding and conservative decision-making essential.

Natural avalanches possible; human-triggered avalanches likely.

Small avalanches in many areas; or large avalanches in specific areas; or very large avalanches in isolated areas.

Very dangerous avalanche conditions. Travel in avalanche terrain not recommended.

Natural avalanches likely; human-triggered avalanches very likely.

Wind Slabs
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?
A significant wind event has set up highly variable wind slabs on north through east aspects. Cross-loading is possible on open slopes generally oriented parallel to the wind, which contain features and gullies able to catch wind-drifted snow.
Travel and Terrain Advice
  • Avoid freshly wind loaded features.
  • Watch for whumpfing, hollow sounds, shooting cracks or recent avalanches.
  • Make observations and assess conditions continually as you travel.
