    Wind slabs can be expected to be most developed in the alpine and open tree-line ridge tops.

    The facetting process is weakening the mid-pack from the top down and bottom up. This situation would make it possible to trigger the weakness at the base of the snowpack as the support underfoot shrinks. Watch for this in shallower areas.

Weather Forecast

High pressure and connected ridge will muscle it's way into region and stay put for the foreseeable future. Which means no new snow but, with the seasonal temps and sunshine, south aspects will be glorious riding and north aspects will stay nice, dry and cool.

Snowpack Summary

Supportive and well settled snowpack above 1700m. Thin wind slabs in the alpine on the lee side of wind exposed terrain. Snowpack continues to facet with recent cold temperatures losing some overall depth as it drys and settles. The base of the snowpack is weakening from the cold but thus far the mid-pack is still bridging this growing weakness.

Avalanche Summary

No new avalanches reported or observed.

Confidence

The weather pattern is stable
