Avalanche Forecast
Regions: Jasper.
Good quality turns can still be found in sheltered areas below tree line that were not hit by Tuesday's wind event.
Weather Forecast
A high pressure system will continue to provide mostly clear skies, light NW winds, no precip and temperatures trending to below seasonal normals.
Snowpack Summary
There are no significant changes in the snowpack over the past 3 days. Previous winds have stripped snow from exposed terrain and resulted in wind slabs and wind affected snow in open terrain below treeline, at treeline and in the alpine. The midpack is supportive. Surface hoar is found down 40cm to 80cm in isolated sheltered locations.
Avalanche Summary
No new avalanches observed today (limited observations) or reported.

Avalanche Problems
Wind Slabs
Previous strong southwesterly winds have resulted in wind slab formation in open terrain features at all elevations. Be most wary of where slab has built over shallow areas, on unsupported slopes, and on steeper solar aspects.
- Avoid steep convexities or areas with a thin or variable snowpack.
- Be aware of thin areas that may propogate to deeper instabilites.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible
Expected Size: 1.5 - 2.5
Persistent Slabs
Use caution around thin to thick areas. Keep an eye out for surface hoar in isolated sheltered locations below treeline.
- Dig down to find and test weak layers before committing to a line.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Unlikely - Possible
Expected Size: 1 - 2.5
