Avalanche Forecast
Regions: Jasper.
Weather Forecast
A small front will pass through in the next day bringing cloudy periods and light snow flurries. Temperatures are expected to cool overnight and remain below 0 during the day at treeline and above. Another system is expected to develop by mid week which will bring a mixture of sun and cloud with only light snowfalls into the weekend.
Snowpack Summary
A shallow and weak snowpack sits on 10-20cm of basal facets. Previous wind slabs provide bridging strength to the snowpack above treeline and into the alpine. Extensive scouring in the high alpine. Clear skies and light winds have developed surface hoar at all elevations leading to another weak layer in the future.
Avalanche Summary
No new avalanches were observed on Saturday. Friday's field patrols observed three size 1.5 to size 2 slabs on solar aspects in the alpine.
Confidence
Timing or intensity of solar radiation is uncertain
