Avalanche Summary

Avalanche activity has mostly tapered off from the warm weather and rain.

Moving forward avalanche activity will become more likely as storm snow accumulates.

Snowpack Summary

Up tp 30 cm of storm snow is expected to accumulate over Saturday. This will fall over moist snow at low elevations, or over a crust at higher elevations.

The middle of the snowpack is generally well bonded in the Lizard and Flathead areas. In the Rockies -there is a layer of sugary facets that are buried 30-50 cm deep and in some places may sit on a crust.

The middle and lower snowpack contains a series of crusts and faceted snow that are more prominent in shallow areas of the Rockies.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • As the storm slab problem gets trickier, the easy solution is to choose more conservative terrain.
  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
