Isolated wind slabs exist on exposed north and east facing slopes in the alpine. Evaluate wind-affected terrain carefully as human-triggered wind slab avalanches are possible.

Moderate
Avalanche Summary
On Tuesday, a size 1 skier accidental storm slab was reported in the McBride area.
We expect users who head into the backcountry on Thursday will find evidence of a small, natural loose wet avalanche cycle from solar input on southerly aspects.
Snowpack Summary
10 to 30 cm of storm snow covers the surface at higher elevations. As winds pick up, the new snow will be redistributed by primarily southwest wind into lee terrain features at alpine and treeline. The new snow sits above a crust or moist snow except on high northerly aspects above 2000 m where snow remained dry.
The lower snowpack is settled and well bonded.

Terrain and Travel Advice
- Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.
- Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
- Closely monitor how the new snow is bonding to the crust.
Problems
Wind Slabs
Where winds have redistributed new snow into lee terrain features watch for slab development. Be especially cautious of north and east facing alpine terrain.
Aspects: North, North East, East, South East, North West.
