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
