Summary

Weather Forecast

Arctic air has pushed back in again. Sunny with a cold -19C for an alpine high along with light to moderate easterly winds. Sunny with cloudy periods for Sunday with alpine high of -16C and similar forecast for Monday.

Snowpack Summary

15cm of settled, faceted snow resides on old wind slabs in sheltered areas. Moderate to strong winds have deposited thin wind slabs on exposed terrain features at ridge-top and exposed areas BTL. A crust on steep solar aspects makes for difficult traveling conditions, both uphill and down. The mid and lower snowpack is well settled and strong.

Avalanche Summary

No new avalanches observed in the highway corridor. Three skier triggered size 1 avalanches occurred Wednesday all reported on the MIN. All three involved small lenses of hard surface wind slab on steep features.
