Avalanche Summary

No new avalanches were reported in this region over the past few days. However, field observations are currently very limited.

If you go into the backcountry, please consider submitting your observations to the Mountain Information Network. 🙏

Snowpack Summary

Up to 10 cm of new snow will overlie 10 to 15 cm of recent snow that has been redistributed by strong southwest winds into wind slabs on lee features at treeline and above.

Below the recent snow is a crust everywhere except true north facing terrain at upper elevations.

Many areas below treeline are either snow free or have very thin snow coverage. Expect difficult travel at lower elevations.
