    Strong southerly wind and new snow may have formed wind slabs in lee terrain features. Assess for slab formation prior to committing to consequential terrain.

Moderate

Avalanche Summary

We haven't received any recent reports for this region. We suspect that riders could trigger small wind slabs in steep lee terrain features.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

Strong southwest wind and around 5 to 10 cm of new snow may have formed small wind slabs in lee terrain features. Southerly slopes exposed to the wind are likely hard with a surface melt-freeze crust or wind-pressed snow.

There are no deeper layers of concern at this time. Thin snowpack areas may host various weak layers lower in the snowpack, which are likely dormant with the cool weather trend.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
