Watch for fresh storm and wind slabs at higher elevations; where a thick surface crust does not exist.

Confidence

Moderate

Avalanche Summary

We expect that natural avalanche activity has stopped since the temperatures have dropped in the aftermath of Monday and Tuesday's warm, wet storm. No new avalanches have been reported.

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

Snowpack Summary

Anywhere form 0 to 20 cm of recent snow may sit overtop a widespread thick crust. New snow may not be bonding well with the underlying crust. This crust should provide a bridge over any previous layers of concern deeper in the snowpack.

Snow depth at treeline is roughly 60 to 80 cm and decreases dramatically at lower elevations.

Weather Summary

Thursday Night

Cloudy with 2 to 5 cm of snow, southwest alpine winds 30 to 40 km/h, treeline temperature -5 °C.

Friday

Cloudy with isolated flurries, west alpine winds 20 to 30 km/h, treeline temperature -7 °C.

Saturday

Cloudy with no precipitation, southwest alpine wind 30 to 50 km/h, treeline temperature -4 °C.

Sunday

Cloudy with 5 to 10 cm of snow, southwest alpine wind 30 to 50 km/h, treeline temperature 0 °C.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
