Assess for wind slabs on lee slopes before entering high-consequence terrain.
Confidence
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.
