Avalanche Forecast

No new avalanches have been reported in this region.

We expect that with the incoming snow, human-triggered avalanches will be possible, 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, 5 to 10 cm of new snow will have buried 10-20 mm surface hoar in the alpine and at treeline.

Above 1800 m, this surface hoar formed on top of 10 - 20 cm of faceting snow over a supportive crust that exists to mountain tops.

Below 1800 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

Mostly cloudy. 2-4 cm of snow expected to near valley bottom. Light southwest ridgetop wind. Treeline low around -4 °C.

Sunday

Cloudy. 3-6 cm of snow expected to near valley bottom. Light southwest ridgetop wind. Freezing level rising to 1250 m through the day. Treeline temperature around -3 °C.

Monday

Sunny. 2-5 cm of snow expected overnight to near valley bottom. Light north ridgetop wind. Treeline high around -4 °C.

Tuesday

Mostly sunny. No new snow expected. Light northeast ridgetop wind. Treeline temperature around -8 °C.

More details can be found in the Mountain Weather Forecast.

• Closely monitor how the new snow is bonding to the old surface.
• Be aware of the potential for larger than expected storm slabs due to the presence of buried surface hoar.
• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
