Avalanche Canada
20 to 35 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.

Avalanche Summary
Numerous naturally and explosive triggered storm slab avalanches up to size 2.5 were reported on mostly northerly aspects at treeline and above near Fernie on Thursday.
Snowpack Summary
20 to 35 cm of recent snow overlies a crust on all but north facing aspects in the alpine.
A widespread crust with facets above is buried up 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.
