In sintesi

Recent snow rests on a weak layer, and likely remains reactive to riders. Don't let good riding lure you into complacency.

    Storm slabs are likely to remain triggerable by riders in wind loaded areas and where the recent snow sits over a weak layer of surface hoar.

Avalanche Summary

Observations have been limited. There have been no recent reports of avalanches in the region.

If you are getting out in the backcountry, consider sharing your observations on the Mountain Information Network (MIN)!

Snowpack Summary

50 to 70 cm of snow fell earlier this week. At upper elevations, wind has loaded deep deposits into leeward terrain. In wind-sheltered areas, the recent snow sits over a weak layer of feathery surface hoar crystals, making for a poor bond.

The mid snowpack contains a crust with small facets above it, but does not present a problem at this time.

The snowpack is around 1 m deep at treeline, tapering quickly with elevation.

Weather Summary

Partly cloudy. 20 km/h west ridgetop wind. Treeline temperature -10 °C.

Terrain and Travel Advice

  • Fresh snow rests on a problematic persistent slab, don't let good riding lure you into complacency.
  • Be aware of the potential for larger than expected storm slabs due to buried surface hoar.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Choose simple, low-angle terrain without steep convex rolls.
