In sintesi

Cautious route finding and conservative terrain choices are required with the unpredictable snow conditions.

    Isolated locations where this layer is persisting. Has morphed into depth hoar in many areas.

Weather Forecast

Generally boring weather forecast. Seasonal temperatures, slight cooling overnight, light winds and no precipitation.

Snowpack Summary

Active wind slabs in the ALP on N to E asps. At TL, soft slab and wind slabs in open areas over a faceted midpack to depth hoar. Nov crust in isolated areas; deeper, sheltered north aspects. Thin rain crust BTL on all aspects below 1600m.

Avalanche Summary

Natural avalanches observed in the alpine from broad, large, wind loaded features from size 2 to 3. One in particular observed in the Boundary area in the Parkers region.

Confidence

The weather pattern is stable
