Avalanche Forecast
Regions: Jasper.
Weather Forecast
Scattered and localized flurries will continue overnight and through the day Sunday. Accumulations may be as much as 4cm overnight and a further 10cm over the day. At lower elevations (under 2200m) expect wet flurries or rain in the afternoon. Winds are expected to shift to the east, remaining light with moderate gusts at ridge top.
Snowpack Summary
14cm HST overnight, with varied localized amounts as unsettled weather continues. Moderate SW winds have certainly overloaded wind slabs and cornices in open areas in the ALP. Persistent instabilities (down 40 to 100 cm) are already sensitive to large triggers like cornices, especially on N asp slopes at TL and ALP elevations.
Avalanche Summary
Road patrols in Maligne and Icefields regions. Very little natural slab activity seen in both regions. It was noted that cornices look huge. Numerous small loose wet slides observed at low elevations and solar asp, up to 2500m. Great information being shared daily on Avalanche Canada's MIN Reports for the Maligne, Whistler's Creek and Ice regions.Â
Confidence
Intensity of incoming weather systems is uncertain on Sunday
