Avalanche Forecast

Moderate - Uncertainty is due to the limited number of field observations.

A relatively weak system brings light snowfall to the western slopes for Friday night and Saturday. A short break is expected Saturday night and Sunday morning before the next system arrives Sunday afternoon. 

Friday night: Snowfall 5-10 cm, strong SW wind, freezing levels around 1200 m. 

Saturday: Snowfall 5-10 cm, strong SW wind, freezing levels around 1200 m.

Sunday: Sunny breaks in the morning, Snowfall 5-10 cm in the afternoon, moderate to strong SW wind, freezing levels reaching as high as 1500 m.

Sunday night: Snowfall 10-20 cm, strong SW wind, freezing levels around 1400 m.

Monday: Light snowfall, moderate to strong W-NW wind, freezing levels dropping to valley bottom.

On Friday, the Avalanche Canada field team reported several size 1-2 storm slab avalanches in the alpine on north through east aspects in the Renshaw area, mostly releasing under cornices. These were failing in the storm snow down roughly 15-30 cm. On Thursday, a loose wet avalanche was reported on a SE aspect at 1800 m east of Prince George which was likely solar triggered. On Wednesday, skiers triggered three size 1-1.5 storm and wind slabs between 1700 and 2000 m. These slabs were 20-50 cm thick. 

Approximately 5-10 cm of new storm snow is reported to have buried a thin breakable crust which extends to roughly 1500 m. The storm snow is settling rapidly at higher elevations and appears to be most reactive on north and east aspects where wind loading has occurred. A layer of faceted snow can likely be found down 30-60 cm from the cold period at the end of December but has not been reactive recently and does not seem to be creating an avalanche problem in most of the region. 

The early-December crust/facet interface can typically be found down 50-150 cm but has been dormant recently and is no longer expected to be creating an avalanche problem in the region. The base of the snowpack is composed of crusts and weak faceted grains, particularly in thin snowpack areas east of the divide. 

• Continue to make conservative terrain choices while the storm snow settles and stabilizes.
• Be alert to conditions that change with elevation and wind exposure.
• Be careful as you transition into wind affected terrain.
