Avalanche Summary

We haven't received any reports of recent avalanche activity.

Please consider submitting your observations to the MIN if you head to the backcountry.

Snowpack Summary

Anywhere from 5 to 15 cm of snow is forecast to accumulate by Thursday afternoon with southwest wind. This snow will build on surface hoar crystals that overly soft or wind affect snow on northerly alpine terrain or a hard melt-freeze crust elsewhere.

Weak faceted grains above a hard crust that formed in early February is buried around 100 to 150 cm deep. The layer is strengthening and is currently dormant.

The remainder of the snowpack is settled.
