Regions: Glacier.

Likelihood of triggering avalanches is still possible, even large avalanches in isolated areas.

Weather Forecast

Today cloudy with sunny periods, no precipitation, an alpine high of -6 deg, freezing level to 1200m and winds SE 20km. No significant precipitation for the for seeable future, with temps near seasonal averages.

Snowpack Summary

30-50cm of recent storm snow is settling and slowly bonding to the mid january interface. 3 layers in the storm snow producing mod-hard results on stability tests with resistant to broken characteristics. The Dec 18th interface is buried approx 1m and unreactive to stability tests, while the Nov 13 crust lies 1.5-2.5m beneath the surface.

Avalanche Summary

Four new avalanches observed yesterday in the highway corridor on N-NE asp to size 2, and no new avalanches reported from the back country. Large destructive avalanches ran full path on Wednesday and Thursday in the Highway corridor up to size 3.5. Reports from the back country observed natural slab avalanches to size 2.5 occurred during storm.

Avalanche Problems

Storm Slabs

Storm slabs are most volatile near ridge crest and terrain exposed to the wind and lee features. Evaluate each slope independently, avoid steep, shallow, unsupported terrain, cornices and terrain traps.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Avoid shallow snowpack areas where triggering is more likely.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 2 - 3
