Highlights

Incoming snowfall should help to insulate the snowpack from daytime warming, and may improve ski quality on high north aspects.  A cautious approach is still warranted where the snowpack is isothermal.

    An isothermal snowpack exists on all aspects below treeline, this will require several days of cooler temperatures to fully stabilize, human triggering is still possible in the meantime.

Weather Forecast

A cold front embedded in a SW flow is bringing cooling temps and light precipitation to the area.Tuesday: Flurries. Accumulation: 5-10 cm. Treeline temperature: Low -5°C, High -2°C. Ridge wind southwest: 15 km/h gusting to 40 km/h. Freezing level: 1900 meters.

Snowpack Summary

The entire snowpack is isothermal below treeline, and higher on solar aspects. A surface crust is forming overnight and breaking down with daytime warming/solar input.  The snowpack has remained dry on shady aspects at higher elevations - in deep areas it is generally well settled and bonded, in shallow areas it is facetted and unsupportive.
