Avalanche Canada
Recent snow has been largely unreactive but it may still be possible to trigger slabs in wind loaded terrain features. Watch for signs of instability like whumphing, cracking or recent avalanches.

Weather Forecast

Avalanche Summary
Recent snowfall has been incremental, warm and sticky and seems to be stabilizing as it accumulates. We have received no reports of avalanche activity or signs of instability.
Snowpack Summary
10-20 cm of recent snow appears to be bonding well to a variety of underlying surfaces including wind affected surfaces and/or a crust that extends up to at least 1200 m on all aspects. Below this, the mid-pack is generally well-settled and strong in most areas.
Weak facets (sugary snow) exist at the base of the snowpack, especially in more shallow snowpack areas further inland.
Terrain and Travel
- Be carefull around freshly wind loaded features.
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
- Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
Problems
Wind Slabs
Whumpfing, cracking, and hollow sounds are all signs of instability that should cause you to back off into lower angle or less wind-loaded terrain.
Aspects: North, North East, East, South East, South.
