    Hard persistent slabs up to 30cm thick are widespread above treeline and appear to be mostly unreactive.  Thin wind slabs may be found in immediate lee areas above treeline with the small amount of new snow and may be touchy.

Weather Forecast

Light scattered snowfalls through Thursday.  Return to more seasonal temperatures (cooling trend).  Winds moderate to strong at ridgetop.

Snowpack Summary

Any small amounts of new snow that fell in the last 48hrs was hard to find in both the Parker Ridge area and the Maligne valley. Recent strong winds have obliterated most loose snow on most aspects above treeline and left a widespread persistent hard slab on the surface, covering 50-70cm of facets.  Below treeline the midpack is weak.

Avalanche Summary

No new avalanches in Jasper or signs of instability related to the widespread persistent hard slab above treeline.

Confidence

Intensity of incoming weather systems is uncertain
