Kernpunkte

Pay attention to the potential for surface hoar below 2150 meters. This layer is producing easy to moderate shears down 30-40 cm.

    A 30-40cm soft slab sits over the Dec 3 surface hoar in an elevation band between 1700 and 2150m. Continue to treat all steep open slopes below treeline with suspicion until you can rule out this weak layer.

Weather Forecast

A ridge of high pressure dominates the area through Friday. Expect to see clearing skies, light north-west winds and cool temperatures. No inputs to significantly change the danger rating or ski conditions are expected.

Snowpack Summary

In sheltered terrain between 1700 and 2150m, 30-40 cm of recent HST sits over the December 3rd surface hoar. Easy to moderate shears found on this interface. No other significant shears have been observed in the snowpack. In the alpine isolated wind slabs exist in immediate lee areas.

Avalanche Summary

No new avalanches observed.

Confidence

The weather pattern is stable
