Avalanche Summary

No recent avalanches have been reported in the region.

If you do head into the backcountry please submit any observations and/or photos on the Mountain Information Network.

Snowpack Summary

he snow surface is moist at treeline and below. As the freezing level falls a new crust will likely form in the alpine.

The mid and lower snowpack is made up of a series of crusts and rounded grains. The snowpack is generally well consolidated.

Overall, the snow depth remains shallow, especially on south facing slopes. Early season hazards are just below the surface.

Terrain and Travel Advice

  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Travelling on skis is hazardous due to a very shallow mountain snowpack.
