Avalanche Summary

A few small rider-triggered storm slabs were reported on Saturday near Fernie.

Snowpack Summary

15 cm of new snow with more on the way sits on a mix of sun crusts, surface hoar in wind-sheltered spots, and wind-affected snow.

The middle of the snowpack is generally expected to be well-settled and stable. An unreactive melt-freeze crust is near the ground.

Total snow depths vary from 100 to 150 cm at treeline.
