Avalanche Forecast
Regions: Jasper.
Increasing Southwest wind with 10-15cm of new snow overnight will create new winds labs in the Alpine and at Tree Line elevations. Expect the hazard to increase throughout the day and watch out for dry loose activity in steep, wind sheltered areas.

Snowpack Summary
As of sunday afternoon, 2-5 cm of new snow sits over a sun crust on solar aspects to Mountain top. A Melt Freeze crust exist's on northerly aspects up to 2200m with dry, well settled snow on true north slopes above that elevation. Moderate wind effect in the ALP.
Avalanche Summary
A few small, size 1 wind slabs have been observed in higher elevation leeward features.
Confidence
Intensity of incoming weather systems is uncertain on Monday
Avalanche Problems
Wind Slabs
Moderate to Strong SW wind will create fresh wind slab on sunday evening. These new wind slabs sit over a variety of firm surfaces including wind effected snow and sun/temperature crusts. Expect the reactivity to increase throughout the day Monday.
- Use caution in lee areas. Recent wind loading has created wind slabs.
- Watch for stiffer feeling snow. Avoid areas that appear wind loaded.
Aspects: North, North East, East, North West.
Elevations: Alpine, Treeline.
Likelihood: Possible
Expected Size: 1 - 2
Loose Dry
Wind sheltered terrain will have 10-15 cm of dry snow sitting over pervious firm surfaces. Expect small, loose dry avalanches in steep sheltered terrain.
- Be careful of loose dry sluffing in steep, confined or exposed terrain.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 1 - 1.5
