In sintesi

Keep your guard up as wind slabs remain sensitive to human triggering.

Seek out sheltered terrain where you can avoid wind slabs and find great riding.

    Recent snowfall and wind have created fresh wind slab, which will be particularly reactive on lee slopes and cross-loaded features. Recent strong wind means wind slabs may be found farther downslope than expected.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.
  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

Poor visibility restricted field observations on Wednesday and Thursday, but natural avalanche activity has likely occurred with the recent wind and storm snow.

Looking forward, avalanche activity will remain sensitive to human triggering over the coming days, as natural avalanche will taper off.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

The latest storm added 20 to 30 cm of additional new snow to the snowpack. Strong to extreme westerly wind redistributed this new snow, farther downslope than normal, forming reactive slabs down to treeline.

This overlies old settling snow in wind-sheltered terrain, hard wind-affected snow in open areas and/or a solid melt-freeze crust in wind-exposed terrain.

The remainder of the snowpack is consolidated with no layers of concern.

Weather Summary

Thursday Night

Cloudy. 5 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -14 °C.

Friday

Mostly cloudy. 1 to 3 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -14 °C.

Saturday

Mostly sunny. 50 km/h west ridgetop wind. Treeline temperature -11 °C.

Sunday

Mostly sunny. 70 km/h west ridgetop wind. Treeline temperature -6 °C.

Terrain and Travel Advice

  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
