    Hard windslabs can be found on a variety of aspects in the alpine and are generally very stubborn to trigger. New thin wind slabs are forming in exposed areas above treeline with recent flurries.

Weather Forecast

Light scattered snowfalls over the course of the week. Temperatures moderating to the -5 to -15 range.  Winds are forecasted to be light at lower elevations and gusting up to 50 km/h at ridgetops.

Snowpack Summary

Light scattered precipitation (1-3cm) throughout Jasper in the past 24 hours.  No significant change to snowpack structure:  windslabs in exposed lee features, faceted midpack at lower elevations, and poor travel with difficult trail-breaking below treeline. Persistent hard slab buried beneath recent storm snow is widespread above treeline.

Avalanche Summary

No new avalanches were observed or reported today.
