Avalanche Summary

There have been no new avalanches reported, but we haven't received any updates from the field since the most recent storm.

If you do head out, do so with a cautious and investigative mindset, and let us know what you're seeing by submitting a MIN report.

Snowpack Summary

Roughly 30 to 60 cm of snow exists at the treeline. A crust or moist snow may exist on the surface from recent warm temperatures and rain. The alpine snowpack has been extensively wind-affected and largely scoured to rock. A robust crust has been reported near the base of the snowpack.

The snowpack remains shallow and creeks are open, rocks are exposed, and there are plenty of early-season hazards.

Weather Summary

Saturday night

Cloudy with snow, up to 10 cm accumulation, southwest alpine wind 40 to 60 km/h, treeline temperature -1°C.

Sunday

Cloudy with snow, 5 to 20 cm accumulation, southwest alpine wind 50 to 70 km/h, treeline temperature -1°C.

Monday

Cloudy with snow, 5 cm to 15 cm accumulation, southwest alpine wind 50 to 80 km/h, treeline temperature -4 C.

Tuesday

Mostly clear with 1 cm to 5 cm accumulation, southwest alpine wind 30 to 40 km/h, treeline temperature -4°C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.
  • Early season avalanches at any elevation have the potential to be particularly dangerous due to obstacles that are exposed or just below the surface.
  • Watch for areas of hard wind slab on alpine features.

Avalanche Problems

Wind Slabs

New snow and southwest wind are expected to have formed fresh wind slab. Wind-loaded bowls and gullies may present as an appealing place to get some early-season turns, but they're also the places where avalanches are most likely to occur.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 2.5
