Regions: East Island, North Island, South Island, Vancouver Island.
Keep decision making conservative in this break in the storm.
Watch for reactivity in wind affected features.
Confidence
Moderate
Avalanche Summary
Natural avalanche activity is expected to have occurred throughout Thursday and Thursday night as snow, wind and rain hammer the snowpack.
Snowpack Summary
Above 1000m, over 50 cm of storm snow can likely be found, redistributed into deeper deposits on north facing terrain features by strong southerly winds.
Storm snow has fallen over settling snow at high elevations. Heavy rain (or wet snow) has likely saturated the snow surface and lower elevations. As freezing levels fall on Friday this may freeze into a hard crust.
The middle and lower snowpack are strong and well-bonded.

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Be especially cautious as you transition into wind affected terrain.
Avalanche Problems
Storm Slabs
Storm slabs are expected to remain reactive to human triggers. Large avalanches are possible due to heavy accumulations of storm snow. Avoid steep open slopes and wind loaded features.
At low elevations where precipitation fell mostly as rain, wet avalanches are possible. Back off slopes that hold wet or slushy surface snow.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible - Likely
Expected Size: 1 - 2
