A few small to large (size 1.5 to 2) slab avalanches were triggered by explosives on Monday. Otherwise, no new avalanches were observed.

Snowfall on Wednesday may form new wind slabs in lee and cross-loaded terrain features at high elevations. This new snow will fall on widespread wind-affected snow at alpine and treeline elevations. Below this, the snowpack is generally well-settled and strong.
