Avalanche Forecast

Riders were involved in a large (size 2) avalanche that they triggered on north-facing slopes off Nak-Thar col on Wednesday. See the report here.

Looking ahead, natural and human-triggered avalanches are expected.

Observations have been limited in this region. Please consider sharing your observations to the Mountain Information Network (MIN).

A stormy Saturday where 15 to 40 cm of snow is expected by the end of the day. This snow will be transported by moderate to strong southwesterly winds, building reactive cornices and slabs on lee slopes.

Below this, reports indicate 20 to 30 cm of snow above a supportive buried crust.

Below treeline, moist snow will likely be observed on the surface.

Snow depths at treeline range from 140 cm in the Coquihalla to 85 cm near Manning Park.

Friday Night

Cloudy with 5 to 15 mm, falling as snow to 750 m. 30 to 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1000 m.

Saturday

Cloudy with 10 to 25 mm, falling as snow to 1000 m. 50 to 80 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1000 m rising to 1200 m.

• It's a good day to make conservative terrain choices.
• Storm slab size and sensitivity to triggering will likely increase through the day.
• Choose simple, low-angle terrain without steep convex rolls.
