Lo esencial

Keep seeking out low density snow in sheltered, low elevation zones for the safest, best skiing and riding.

    More strong northeast outflow winds on Saturday means our recent snow will be getting packed into new wind slabs on lee slopes. Older, buried slabs may remain reactive to human triggering on steeper, unsupported features.

Confidence

Moderate - Due to the number of field observations

Avalanche Summary

No new avalanches have been reported in the region.Our most recent avalanche observations are from Monday. They showed small (size 1) wind slabs releasing naturally from steep, wind loaded pockets in the Howson range.Numerous avalanches were triggered by skiers and naturally within the recent storm snow on the weekend. Check out this MIN report describing widespread slab activity.

Snowpack Summary

Up to 20 cm of new snow fell over the region on Wednesday night and is being redistributed by predominantly northeast winds. The new snow buried 20-40 cm of storm snow from the weekend that became wind-affected early in the week and has since been faceting (becoming sugary) under the influence of cold temperatures. This older, faceting storm snow overlies previously wind-affected snow in the high alpine and a widespread melt-freeze crust elsewhere. In the central and northern parts of the region, it may sit on 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, 50 to 100 cm of snow may overlie two weak layers of surface hoar or sugary faceted grains.
