Points saillants

Extremely cold temperatures will make travel slow and the ice hard and brittle. Bundle up and watch your partners for frostbite.

    Strong northerly winds from a few days ago redistributed snow into isolated pockets of wind slab at alpine elevations.

    This layer is well bridged by a strong mid and upper snowpack but could still be triggered from shallow or rocky terrain or by a large load.

Weather Forecast

A reprieve from these arctic temperatures is forecast for next week when we might also get a little snow :)

Snowpack Summary

Surface facetting due to extremely cold temps. Hard mid-pack is providing bridging strength over the weak basal facet layer at tree line and above. Recent settlement below tree line has greatly improved travel. Reasonable ski conditions can be found in sheltered features at tree line and below.

Avalanche Summary

No new avalanches observed today.
