Choose mellow terrain and constantly assess the bond of the new snow to the old surface.

Avalanche danger is increasing through the day as new snow accumulates over weak, feathery crystals.




Avalanche Summary

No new avalanches have been reported in this region.

We expect that with the incoming snow, human-triggered avalanches will be likely, especially where the new snow falls on preserved surface hoar.

If you do go into the backcountry, please consider submitting a MIN report.

Snowpack Summary

By the end of the day on Sunday, 15 to 25 cm of new snow will have buried 10-20 mm surface hoar in the alpine and at treeline.

Above 1900 m, this surface hoar formed on top of 10 - 40 cm of faceting snow over a supportive crust that exists to mountain tops.

Below 1900 m, the new snow will probably sit right over the crust.

Where snow still existed below treeline, it was isothermal or refrozen. Even with some new snow at lower elevations, travel will remain challenging.

Weather Summary

Saturday Night

Cloudy. 5-7 cm of snow expected to near valley bottom. Light southwest ridgetop wind. Treeline temperature around -2 °C.


Cloudy. 10 to 15 cm of snow expected above 500 m. Light to moderate southwest ridgetop wind. Treeline temperature around -2 °C.


Sunny. 3 to 7 cm of snow expected above 600 m overnight. Light to moderate north ridgetop wind. Treeline high around -2 °C.


Sunny. No new snow expected. Light northeast ridgetop wind. Freezing level dropping to 250 m overnight, rising back to 900 m through the day. Treeline temperature around -7 °C.

Terrain and Travel Advice

  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • Be aware of the potential for larger than expected storm slabs due to the presence of buried surface hoar.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.


Storm Slabs

An icon showing Storm Slabs

New snow is building up over 10-20 mm surface hoar in alpine and high treeline terrain throughout the day. If these large, feathery crystals stay preserved, avalanches could be bigger and more easily triggered than you'd expect.
