Avalanche Summary

No recent avalanche observations reported.

Snowpack Summary

There is not enough snow yet for avalanches below treeline, but expect to find a metre or more at treeline and above. The upper snowpack is likely moist and heavy with deep wind drifts on leeward slopes. A thick crust is can probably be found down around 50cm at treeline elevations. When traveling in the mountains Id maintain an investigative approach and dig down to test for weak layers before committing to a slope. If you've been in the mountains, please share your observations on our Mountain Information Network.

Problems

Storm Slabs

Touchy storm slabs are likely lurking on steep open slopes at higher elevations. Human triggering is likely.

Avoid avalanche terrain at upper elevations during periods of loading from new snow and wind.Be cautious as you transition into wind affected terrain.Be alert to conditions that change with elevation.

Aspects: All aspects.
