Continue to assess for fresh wind and storm slabs that are likely sitting on a hard crust.

Low

Avalanche Summary

No new avalanches have been reported. However, observations have been minimal throughout the early winter.

If you're heading out in the backcountry, please consider sharing any observations on the Mountain Information Network

Snowpack Summary

Approximately 10 to 30 cm of recent snow may sit overtop a widespread thick crust. New snow may not be bonding well with the underlying crust. Below the crust the snowpack is generally well consolidated.

Overall, the snow depth remains relatively shallow, creating challenging travel conditions and numerous hazards at or just below the snow surface across all elevations.

Weather Summary

Saturday Night

Cloudy with 5 to 15 cm of snow, southwest alpine winds 40 to 60 km/h, treeline temperature -3 °C.

Sunday

Cloudy with 2 to 10 cm of snow, southwest alpine winds 30 to 50 km/h, treeline temperature 0 °C, freezing level 2000m in the morning and gradually dropping through the day.

Monday

Mostly sunny with no precipitation, southwest alpine winds 10 to 30 km/h, treeline temperature -3 °C.

Tuesday

Mix of sun and cloud with no precipitation, southwest alpine winds 30 to 40 km/h, treeline temperature -2 °C, freezing level rising to 2500 m by end of the day.

Terrain and Travel Advice

  • Avoid areas where the snow feels stiff and/or slabby.
  • Closely monitor how the new snow is bonding to the crust.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
