Human-triggered persistent slab avalanches remain a concern in areas not capped by a thick surface crust.
Concern remains for human-triggering the persistent weak layer on sheltered north aspects above 1800 m. If triggered, avalanches will be large and destructive. Avoid shallow snowpack areas where triggering is more likely.
No recent avalanches have been reported in the region.
If you are heading into the backcountry please consider posting your observations to the Mountain Information Network. We read every report!
A dusting of snow overlies a thick crust capping a moist upper snowpack on all but direct north aspects above 1900 m, where dry settled snow can be found.
A significant crust/facet layer is buried 60 to 170 cm deep. It was reactive to human triggering over a week ago and continues to be reactive in snow pit tests. Human-triggering remains a concern on northerly aspects above 1800 m.
Below the crust, the snowpack is well settled.
