Avalanche Forecast
Regions: Jasper.
Weather Forecast
Winds will continue to redistribute snow in the alpine and treeline elevations. Light snow will turn to rain at lower elevations as we go into a warming cycle.
Snowpack Summary
Up to 70cm of storm snow has been redistributed by moderate to strong SW winds creating wind slab over a strong mid-pack in lee features on top of a weak basal facets layer at the ground.
Avalanche Summary
A field team in the Maligne Lake area remotely triggered a size 2.5 from a distance of 20m. In the Icefields area a group remotely triggered a size 1.5. Both avalanches were on open slopes at treeline and ran on the basal facet layer. Whumphing and shooting cracks were observed in both locations. Some natural activity to size 2.5 observed.
