We have reports of isolated natural avalanches up to size 2.5 from both the Duffey lakes and the Coquihalla areas predominantly on north aspects at or slightly above treeline. Numerous ridder triggered avalanches up to 1.5 have also been seen in the recent storm layers (top 30cm).

In the west side of the Duffey lake region up to 20cm of new snow fell in the last 24 hours, while on the east side the values are roughly half that. The Coquihalla area received roughly 30cm. This brings the recent storm values up to 40/30/60 respectively. The southerly winds have lee loaded open treeline and alpine terrain that faces north through east. Compounding the wind slabbing, the increasing temperatures have settled much of the storm snow into a cohesive storm slab, especially at treeline and below. The new snow sits on a variety of surfaces including crusts at lower elevations, surface hoar in protected areas and hard windslabs in the alpine. Below this the lower snowpack is well bonded and strong.
