    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.
