Avalanche Summary

We haven't received reports of recent avalanche activity. Looking forward, human-triggering of wind slabs remains possible in steep lee terrain features at higher elevations.

Please consider submitting to the Mountain Information Network if you are getting out in the backcountry.

Snowpack Summary

Around 10 to 20 cm of new snow accumulated with strong southerly wind. The storm formed wind slabs in lee terrain features at higher elevations. The precipitation fell as rain below 1100 m.

The remainder of the snowpack is strong.

There is insufficient snow to form avalanches for most below treeline elevations.

Weather Summary

Thursday Night

Mostly cloudy with 2 to 5 cm of snow. 10 to 20 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Friday

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
