    Winds are expected to shift recent snow into slabs behind terrain breaks like ridges and ribs.

Confidence

Fair - Due to the number of field observations

Weather Forecast

Cold and clear with strong outflowing N-NE winds.

Avalanche Summary

Over the last three days we've had reports of naturally and skier-triggered size 1-2 slabs, mostly wind slabs on lee slopes at treeline and above. Explosive control on Wednesday produced storm slab and wind slabs up to size 2.5.

Snowpack Summary

Up to 30cm new snow from Friday night may have buried old wind slabs. New wind slabs are likely to form on south to west-facing slopes as we shift into an outflow wind pattern. The mid and lower snowpack are generally well-settled. Several old crust layers exist but these appear to be well bonded.
