Snowpack Summary
Poor overnight crust recovery, weak crusts on all aspects up to 2000m. Crusts at higher elevations will gradually break down with daytime warming. 10-20cm of settled dry snow in high Northerly terrain. Isolated pockets of wind slab may exist in the alpine.

Avalanche Problems
Loose Wet
With a poor overnight crust recovery and a freezing level up to 3000m on Thursday, expect wet loose activity on all aspects but high Northerly terrain.
- Use caution on solar slopes if the snow is moist or wet.
- Avoid slopes when the solar radiation is strong, especially if they have large cornices overhead.
Aspects: South East, South, South West, West.
Elevations: All elevations.
Likelihood: Likely
Expected Size: 1 - 2
Wet Slabs
As the snowpack warms there is potentially for large and deep avalanches. Plan to be off large terrain features before it gets warm, as uncertainty exists about this problem.
- If triggered loose wet sloughs may step down to deeper layers resulting in larger avalanches.
- Use extra caution on solar slopes if the snow is moist or wet.
Aspects: South East, South, South West, West.
Elevations: All elevations.
Likelihood: Possible
Expected Size: 2 - 3.5
