Regions: Glacier.

Try approaching your descent line from the top, knowing there may be a windslab from the previous storm. Bold up-tracks heading straight up the guts of a slope are challenging the main avalanche problem from the wrong direction.

Weather Forecast

Today mainly cloudy with no precipitation, an alpine high of -10*C, freezing level to 900m and light winds. No significant precipitation for the remainder of the week. A high pressure ridge is blocking any major weather systems and sending them to the Yukon.

Snowpack Summary

Storm snow is settling and bonding to the mid-January interface. Cool night time temps have aided in extracting slab properties out of the new snow, leaving it right side up. Stability tests produced mod-hard results with resistant to broken characteristics. Dec 18th interface is buried 1m and unreactive to stability tests.

Avalanche Summary

Natural avalanche activity has eased off in the last couple of days. No new avalanches were observed in the highway corridor yesterday. Small loose point releases were observed from steep easterly aspects above Teddy Bear Trees.

Avalanche Problems

Wind Slabs

Wind slabs are present at ridge-top and on cross-loaded alpine features. They overlay a variety of old surfaces, from facets to surface hoar to old wind slabs. They are most reactive in shallow, thin snowpack areas.
Choose well supported terrain without convexities.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2
