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.
