Avalanche Forecast
Regions: Blue River, Cariboos, Clearwater, Clemina, McBride, Premier, Quesnel, Renshaw, Robson.
Large persistent slab avalanches continue to be reported, primarily on northerly aspects in the alpine.
Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
Confidence
Moderate
Avalanche Summary
On Monday, numerous naturally triggered wet loose avalanches up to size 2.5 and a size 2 cornice failure were reported.
On Sunday, cornice falls triggered two size 3 persistent slab avalanches on northerly aspects in the alpine near McBride.
On Saturday, a sledder triggered size 2 persistent slab avalanche was reported below an alpine ridgetop near the Clemina Creek. See MIN
NOTE: Observations in this region are currently very limited.
Snowpack Summary
Recent convective snowfall has been highly variable, accumulating over a crust in most areas except shady aspects in the high alpine where soft or wind affected dry snow may be found.
The primary weak layer of concern is a surface hoar, facet, and crust layer from early March, buried 50 to 100 cm deep.
The lower snowpack is generally well settled and strong in most areas.

Terrain and Travel Advice
- Cornice failures could trigger large and destructive avalanches.
- Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
- Triggering deep layers is more likely if the snow surface didn't freeze overnight.
