Regions: Northwest Inland.

More snow will accumulate Thursday night into Friday, with the highest amounts expected in the south of the region. Best to treat this snow with added caution and apply conservative travel techniques.

Confidence

Moderate - Timing, track, or intensity of incoming weather system is uncertain

Weather Forecast

THURSDAY NIGHT: Cloudy with snowfall, accumulation 10 to 15 cm, freezing level below valley bottom.FRIDAY: Cloudy with snowfall, accumulation 5 to 10 cm, light to moderate southwest winds, alpine temperature -15 C, freezing level below valley bottom.SATURDAY: Cloudy with light snowfall and afternoon clearing, trace accumulation, light north winds, alpine temperature -27 C, freezing level below valley bottom.SUNDAY: Clear skies, strong northeast winds, alpine temperature -30 C, freezing level below valley bottom.

Avalanche Summary

No new avalanches were observed in the region on Wednesday. The likelihood of triggering avalanches will increase on Friday with the new snow.

Snowpack Summary

New snow is falling onto a wind-affected surface in high alpine and a widespread melt-freeze crust elsewhere. In the central and northern parts of the region, this snow may fall onto feathery surface hoar crystals in sheltered terrain at all elevations.In the south of the region, the remainder of the snowpack has been reported as well-settled.Around and north of Hazelton, 40 to 100 cm of snow may overly two weak layers of surface hoar found in sheltered and shaded areas. A weak layer of sugary faceted grains may also exist, approximately 150 to 200 cm deep.

Avalanche Problems

Storm Slabs

The storm snow will likely be touchy to human traffic on Friday. It also may load weak layers in the centre and north of the region (see Snowpack Summary).
Make observations and assess conditions continually as you travel.Good day to make conservative terrain choices.Be careful with wind-loaded pockets adjacent to ridge crests and roll-overs.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 2
