Regions: Northwest Inland.

Variable amounts of snow will fall in the region on Thursday. Where it accumulates, the snow may not bond well to underlying layers and be reactive to human traffic.

Confidence

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

Weather Forecast

WEDNESDAY NIGHT: Cloudy with snowfall, accumulation 5 cm, freezing level below valley bottom.THURSDAY: Cloudy with snowfall, accumulation 5 to 10 cm, light to moderate southwest winds, alpine temperature -4 C, freezing level below valley bottom.FRIDAY: Cloudy with snowfall, accumulation 5 to 10 cm, light to moderate south winds, alpine temperature -15 C, freezing level below valley bottom.SATURDAY: Mostly cloudy with light snowfall, trace accumulation, light southwest winds, alpine temperature -25 C, freezing level below valley bottom.

Avalanche Summary

No new avalanches were observed in the region on Tuesday.

Snowpack Summary

New snow will fall onto a wind-affected surface in high alpine, a widespread melt-freeze, and feathery surface hoar crystals in sheltered areas.In the south of the region, the remainder of the snowpack has been reported as generally well-settled.Around and north of Hazelton, 40 to 100 cm of snow may overly two weak layers of surface hoar 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 new snow may be touchy, as it may not bond well to the layers it is falling on. Assess for the bond of the snow before committing to avalanche terrain.

Be careful with wind-loaded pockets adjacent to ridge crests and roll-overs.Watch for signs of instability such as whumpfing, cracking, or recent avalanches.Make observations and assess conditions continually as you travel.

Aspects: All aspects.

Elevations: All elevations.
