    Avalanches may be triggered in lee features and on extreme terrain. We advise that riders/skiers choose routes carefully before committing to aggressive lines.

Weather Forecast

No significant precipitation is expected as a ridge of high pressure affects the region for the next few days. Cold overnight temperatures with daytime Highs to -4 at 1500m. Winds will continue to come from the NW.

Avalanche Summary

One size 2 human triggered avalanche Monday in a steep rocky feature on an east aspect. Some sluffing observed in steep terrain Tuesday.

Snowpack Summary

A generally well settled snowpack with up to 12 cm new snow deposited overnight Tuesday. Wind slab is the predominant stability concern right now. It may be resting on suncrust or surface hoar which was buried on Feb 4. The Jan 23 interface appears to be inactive but can still be found  40-60 cm below the surface. It may be worth investigating on an adjacent slope before riding in aggressive terrain.
