The snowpack needs time to adjust to the new snow.

Keep terrain choices low-angle and safe as the storm snow settles.

Moderate

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.

  • Minimize exposure during periods of heavy loading from new snow and wind.
  • Don't let storm day fever lure you into consequential terrain.
