Wind Slabs
What Elevation Zone?
Which Slopes?
Chance of Avalanches?
Expected Size?

Lingering wind slabs may still exist in isolated alpine lee terrain. Forecast variable winds may create wind slabs on varying aspects, take note of recent wind directions.

Travel and Terrain Advice
  • Use ridges or ribs to avoid pockets of wind loaded snow.
  • Caution in lee and cross-loaded terrain near ridge crests.
