Avalanche Forecast

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.

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.

Saturday Night

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

Sunday

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

Monday

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

Tuesday

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.

• 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.
