, the treeline rating is , and the below treeline rating is Known problems includeAvalanche hazard will increase through the day where heavy snow accumulates.
Summary
Confidence
Moderate - Uncertainty is due to difficult to forecast freezing levels.

Avalanche Summary
A few small (size 1) wet-loose avalanches were observed on Thursday morning as the rain event began.
Snowpack Summary
Recent warm temperatures and rain saturated the snowpack to 1900 m. Where dry snow prevailed (at the highest elevations), winds have scoured and redistributed about 20 cm new snow developing slabs and building cornices.Â
Rain earlier in the week created a strong and settled snowpack, which is now 250-300 cm deep around the peaks of the North Shore mountains.
Terrain and Travel
- Minimize exposure during periods of heavy loading from new snow and wind.
- Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
- As surface loses cohesion due to melting, loose wet avalanches become common in steeper terrain.
Problems
Storm Slabs
Thick storm slabs will form as heavy snowfall accumulates.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Loose Wet
Rain and warm temperatures will encourage wet-loose avalanches in steep terrain at lower elevations.
Aspects: All aspects.
Elevations: Treeline, Below Treeline.
