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
A crust will likely form on all aspects treeline and below as well as solar aspects in the alpine. below this new crust up to 20cm of dry snow sits on the early February crust. This is followed by another 30 to 50cm of dry snow and then the late January crust which is at least 10cm thick and extends to mountain tops on all aspects.
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.
- Watch for fresh storm slabs building throughout the day.
Problems
Wind Slabs
Rider triggerable wind slabs can be found in exposed treeline and alpine features on North and east aspects.
In deeper snowpack areas on the west side of the forecast region storm slabs may form at treeline and above. Storm slabs produce up to size 2 avalanches.
