Weather Forecast

FRIDAY: Cloudy with new snow amounts up to 10 cm. Treeline temperatures near -5 and ridgetop winds light from the northeast.SATURDAY: A mix of sun and cloud. Treeline temperatures near -8 and ridgetop winds moderate from the northeast. SUNDAY: Mostly sunny with treeline temperatures near -6. Ridgetop winds mostly light from the northeast with strong gusts.

Avalanche Summary

Loose dry sluffing from steeper terrain features up to size 1.On Monday, a MIN report from Mt. Anif showed substantial wind loading and a reactive wind slab problem at treeline and alpine elevations. Check it out HERE.

Snowpack Summary

In the alpine, 40-60 cm of wind affected snow sits above a crust or old wind pressed snow surfaces. This tapers significantly below treeline and new surface hoar is forming. Strong outflow winds have redistributed and formed isolated wind slabs at most elevations. Loose dry sluffing within the recent snow can be found in steeper terrain features. The mid-pack is well-settled and strong.

Problems

Wind Slabs

Sifting winds and strong outflows have formed wind slabs on a variety of aspects at upper elevations. Loose dry sluffing of the recent storm snow can be found in steeper terrain features at all elevations,

Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Watch for whumpfing, hollow sounds, and shooting cracks.

Aspects: South East, South, South West.
