Avalanche Summary

Despite the lack of reports, we suspect a natural avalanche cycle to have occurred during the peak of the warming event (Monday night).

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

Snowpack Summary

A widespread thick crust continues to form in the aftermath of Monday's warm, wet weather. This crust should provide a bridge over any previous layers of concern deeper in the snowpack.

Weather Summary

Tuesday Night

Cloudy with up to 10 mm of rain and 5 cm of snow at higher elevations, southwest alpine winds 30 to 50 km/h, treeline temperature 0 °C, freezing level around 1700 m.

Wednesday

Cloudy with trace precipitation in the morning, southwest alpine winds 20 to 30 km/h, treeline temperature -1 °C, freezing level 1500 m and dropping.

Thursday

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

Friday

Cloudy with 5 to 10 cm of snow, southwest alpine winds 30 to 50 km/h, treeline temperature -6 °C.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Snow is accumulating at higher elevations despite lower elevations being almost snow free
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
