New snow and strong wind are developing wind slabs. Human-triggered avalanches are possible. Assess for signs of instability like shooting cracks as you transition into open terrain.

Summary

Confidence

Moderate

Avalanche Summary

On Saturday explosive triggered wind slabs up to size 3, failing on the crust layer were reported in the south of the region.

Suspect the east side of the region to see increased wind slab activity with moderate to strong southwest winds.

Snowpack Summary

New snow is being redistributed by moderate to strong southwest winds developing wind slabs at all elevations over various surfaces of wind-affected snow, soft snow, and a crust layer.

Below this crust, the shallow faceted snowpack is generally well consolidated. Two crust layers, one in the midpack and another near the base of the snowpack continue to be monitored. Avalanches on these layers are unlikely.

  • Seek out sheltered terrain where new snow hasn't been wind-affected.

15 to 20 cm of new low-density snow is available for transport. increasing winds from the southwest will redistribute new snow into reactive wind slabs in lee terrain features at all elevations

Aspects: North, North East, East, South East, North West.
