Over the past week, observers near Duffey Lake reported a large (size 2.5) avalanche on a north aspect at 1750 m that was thought to have released 1 m deep on a persistent weak layer. On Sunday, a size 1.5 skier accidental was reported on a northwest aspect in the alpine, also near Duffey Lake. The slab is thought to have failed on a thin layer of facets, sandwiched between two wind-stiffened layers.

In the Coquihalla area, several natural glide slab avalanches size 2-2.5 have been observed. Glide slabs are notoriously difficult to forecast but with the sustained warming, we may see continued activity. Glide slabs are most likely in areas of smooth ground cover such as rock slabs at lower elevations experiencing prolonged warm temperatures with limited overnight refreeze. These avalanches will be large, involving the full depth of the snowpack. Carefully consider your access/egress routes where they cross under large paths.
