Regions: Northwest Inland.

New snow will likely take a few days to gain strength.

Confidence

Fair - Due to the number of field observations

Weather Forecast

Isolated lingering flurries are expected for Thursday as freezing levels drop to valley bottoms and alpine winds ease off to moderate southerlies. Continued unsettled weather is expected for Friday and Saturday with some sunny breaks and isolated light flurries. Freezing levels should remain in valley bottoms with light alpine winds.

Avalanche Summary

There are no new avalanche reports from the region. Please let us know what you're seeing out there. Submit your observations through the Mountain Information Network.

Snowpack Summary

Rain-soaked snow should soon be frozen into a solid surface crust that extends as high as treeline elevations with 15-20 cm of fresh snow on top, depending on elevation. Meanwhile above the previous freezing levels fresh storm and wind slabs have likely developed and weakness deeper in the snowpack, such as crusts with associated facets, likely remain under critical loads. Check out the Bulkley Valley Ski Society Facebook page for recent observations from the Hankin and Evelyn areas.

Avalanche Problems

Storm Slabs

Fresh new storm and wind slabs are likely susceptible to human triggering especially on the northwest through northeast side of terrain breaks. Facet/crust weaknesses deeper in the snowpack are likely under critical loads at treeline and above.

Choose well supported terrain without convexities.>Use ridges or ribs to avoid wind loaded and cross loaded slopes.>

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 3
