Avalanche Canada
30 to 50 cm of recent snow has formed storm slabs that are reactive to human triggers, especially in wind affected terrain.
Use small low consequence slopes to test the bond of the new snow.
Summary
Confidence
Avalanche Summary
Numerous natural and rider triggered storm slab avalanches up to size 2 were reported on all aspects/elevations on Thursday.
Snowpack Summary
30 to 50 cm of recent snow overlies a crust on all but north facing aspects at treeline and above where a weak layer of surface hoar may be present.
A widespread crust with facets above is buried 80 to 180 cm deep. Steep or convex terrain features with a shallow or thin to thick snowpack at treeline and above are the places where it may still be possible to trigger this layer with large loads.

Terrain and Travel Advice
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
- Use small low consequence slopes to test the bond of the new snow.
- Watch for changing conditions today, storm slabs may become increasingly reactive.
- If triggered loose wet avalanches may step down to deeper layers resulting in larger avalanches.
- Cornice failure may trigger large avalanches.
