Avalanche Canada
Recent snow and wind have developed isolated wind slabs at treeline and above. As you transition into open terrain, look for signs of instability, like shooting cracks.

Avalanche Summary
Several small explosive-triggered wind slabs and size 1 to 1.5 wet loose from steep solars on Friday.
On Thursday, a few size 1 skier-triggered wind slab avalanches were reported in the Golden area.
Even short windows of sun coupled with rising freezing levels may initiate wet, loose avalanches on steep solar-facing slopes.
Snowpack Summary
Roughly 20 to 25 cm of accumulated new snow is settling and could become moist on steep south-facing slopes. This new snow overlies a crust on all aspects and elevations that are more robust on solar-facing slopes.
A widespread crust with facets above is down 60 to 110 cm. This layer is unlikely to human trigger in areas where a thick crust above the weak layer is present.

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- Wind slabs may be poorly bonded to the underlying crust.
Problems
Wind Slabs
New snow and variable winds have developed isolated wind slabs at treeline and above. These wind slabs are most likely found directly lee of high points and ridge features.
Aspects: South East, South, South West, West, North West.
