Regions: East Island.

Avalanche danger will increase through the day as storm and wind slabs form in the alpine and upper treeline elevation bands.

Travel cautiously at lower elevations. A fresh dusting of new snow may start to obscure early-season hazards.

Avalanche Summary

Observations are limited at this time of year. No new avalanches have been reported or observed. If you do head into the backcountry consider submitting a MIN report!

Snowpack Summary

A variable snowpack depth of between 20-100 cm exists in the region. Expect early season conditions and rugged travel. Below treeline is below the threshold for avalanches.

Terrain and Travel Advice

  • Watch for avalanche hazard to increase throughout the day.
  • Wind slabs are most reactive during their formation.

Avalanche Problems

Wind Slabs

Snow accumulating through the day combined with by strong southwest winds will develop wind slabs that will become more reactive as the day progresses.

Aspects: All aspects.
