Watch out for wind slabs in unusual places, such as south-facing slopes and lower down slopes than you might expect.
Wind-sheltered terrain should still offer excellent riding conditions.

Moderate
Avalanche Summary
Since the end of last week, a few natural wind slab avalanches have been reported during active wind transport from northerly winds. Avalanches have generally been on southerly aspects at treeline and above, up to size 2.5.
Several small loose dry avalanches have been reported in wind-sheltered terrain at lower elevations.
If you head into the backcountry, please consider submitting a MIN report.
Snowpack Summary
Wind-affected snow surfaces in exposed terrain at treeline and above, including reactive wind slabs on south-facing terrain due to recent northerly winds. In wind-sheltered terrain, snow remains largely unconsolidated powder.
Roughly 100 cm of recent snow sits atop a crust with a generally well-settled and stable lower snowpack.
With recent snowfall lower elevation areas may now be at the threshold for avalanches.
Weather Summary

Terrain and Travel Advice
- Avoid lee and cross-loaded slopes at and above treeline.
- Seek out sheltered terrain where new snow hasn't been wind-affected.
Problems
Wind Slabs
Winds have been variable so assess for wind slabs on all steep slopes. Reactive slabs may exist lower on slopes than usual and near ridge crests and high points. Watch for cross-loading in features like mid-slope gullies and rollovers.
Aspects: East, South East, South, South West, West.
