    Variable direction, strong upper elevation winds are continuing to create fresh windslabs and stiffen the snow surface well into Treeline locations.

    Whumpfing and cracking are signs of this layer's reactivity. Expect long propagation with a wind-stiffened snow surface.

Snowpack Summary

Available snow has been redistributed by strong, variable direction winds. At all elevations, where transported, new wind slabs will be sensitive to triggering. A persistent slab, down 50 to 80cm, is prevalent through the forecast region. Any large TL avalanche terrain that has not obviously avalanched should be expertly managed or, avoided.

Avalanche Summary

No new avalanche activity observed or reported.

Confidence

Weather Forecast

Gusty North winds expected to persist overnight and through the day Sunday. Temperatures will continue to drop with overnight temperatures to -27, and Sunday's daytime high near -23 for the whole bulletin region.
