New snow may not bond well to the crust below, watch for reactivity on steep slopes and near ridgelines.

Highest storm totals are expected in the Southern Purcells




Avalanche Summary

We expect slab avalanche activity to increase on Sunday with cooler temperatures and fresh snowfall.

Snowpack Summary

Storm totals are expected to reach 10-20 cm by Sunday afternoon. This snow accumulates over a crust at most elevations where it may not bond well. Below 1500 m surface snow may remain moist or wet.

A layer of facets (and small surface hoar in some areas) is buried 30-60 cm deep and a layer of facets on a crust is buried 80-100 cm deep. While cooler temperatures have allowed these layers to strengthen we continue to monitor them for signs of reactivity.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
