Confidence

Moderate

Avalanche Summary

Recent avalanche reports have been limited to small, loose dry avalanches in steep, shaded terrain.

Looking forward to Friday, we expect that natural and human triggered avalanches will be likely to very likely.

If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network)

Snowpack Summary

15 to 40 cm of new snow is expected by the end of the day on Friday. Extreme ridgetop winds will make for widely varied conditions in wind exposed terrain. The new snow may not stick well to the soft, faceted snow underneath.

Below the new snow, 40 to 80 cm of loose snow sits over a crust that exists on all but high north aspects.

The mid and lower snowpack is generally settled and strong.

Below treeline areas once again have enough snow to produce avalanches. Watch for "early season" type hazards such as shallowly buried stumps, rocks and creeks.
