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

Weather Forecast

No precipitation expected other than very light scattered flurries. Freezing levels staying below 1600m. Minimal wind expected, light Southerly.

Snowpack Summary

Wind slabs in the alpine primarily on N to E asps. At treeline, 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 in the past 48hrs.

Confidence

Due to the number of field observations
