Avalanche Summary
On Thursday our field team observed several loose wet avalanches up to size 1.5 in the treeline and above. Ski cutting produced small wet slabs running on a crust down 15cm at 1100m.
Snowpack Summary
Recent snowfall will have formed storm and wind slabs at treeline and above. Below this a 1 cm thick crust can be found up to 1400 m.
Another crust can be found down 30 to 50 cm that extends up to mountain tops.
Moist snow surfaces can be found at and below treeline from rain and warm temperatures.
The mid and lower snow pack is well settled but shallow at low elevations leaving many hazards just below the surface.
Terrain and Travel
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
- Back off slopes as the surface becomes moist or wet with rising temperatures.
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
Problems

Wind slab will likely be found in exposed terrain at and above treeline.
In areas where more than 25 cm of snow has fallen storm slabs are possible on all aspects. This is most likely to have occurred on the western side of the forecast region. Storm slabs could produce avalanches up to size 2.
Aspects: North, North East, East, South East, South.
