Points saillants

Surface conditions and recent precipitation amounts are variable. Verify conditions as you gain elevation, and back off steep slopes if you find moist surface snow.

    Recent new snow has accumulated at upper elevations over a melt-freeze crust and will likely release on steep slopes with even short periods of sun. Watch out for moist surfaces and back off steep slopes where the crust is breaking down.

Confidence

Moderate

Avalanche Summary

No new avalanches were reported. Looking forward, wet loose avalanches are likely with even short periods of sun and rising freezing levels.

Large destructive avalanches were widespread throughout the warm-up, involving persistent weak layers.

Read the Forecaster Blog for an opportunity to reflect on this week's widespread avalanche activity.

Snowpack Summary

Recent new snow overlies a melt-freeze crust that is more supportive as you gain elevation. Surface crust may break down with fluctuating freezing levels and even short windows of sun during the day.

Below this, the upper snowpack has been slow to refreeze and may remain moist in some areas.

The mid and lower snowpack is well settled.

Terrain and Travel Advice

  • Avalanche danger will increase as the surface crust breaks down.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
