Avalanche Summary

No recent avalanches have been reported in the region.

Snowpack Summary

In the alpine, 40-60 cm of storm snow fell last weekend and sits above a crust or heavily wind affected old snow surfaces. Strong outflow winds have redistributed and formed isolated wind slabs at most elevations. At the treeline elevation and below 5-10 cm of snow from last weekend now sits on a supportive crust. The mid-pack is well-settled and strong.

Avalanche Problems

Wind Slabs

Wind shifting from South to North has created wind slabs on a variety of aspects at all elevations.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Stay alert to changing conditions with elevation.Watch for whumpfing, hollow sounds, and shooting cracks.

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

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
