Dangerous avalanche conditions persist where surfaces remained dry through the storm.

Natural activity may taper off but human-triggered avalanche activity remains likely.

Confidence

Moderate

Avalanche Summary

Explosive control in the region produced storm slab avalanches to up to size 2.5. No natural avalanches were reported by 4 pm on Wednesday however poor visibility and high avalanche hazard kept many users out of the backcountry.

If you do head out please consider reporting and observations and photos from your day to the Mountain Information Network.

Snowpack Summary

50 to 70 cm of settling storm snow overlies a crust at lower elevations and wind-affected surfaces in the alpine and exposed treeline.

The mid and lower snowpack are generally well consolidated. The recent snow has improved travel conditions at lower elevations, but many obstacles, such as sticks and rocks, lurk just below the surface.

Weather Summary

Wednesday Night

Cloudy with 10 to 15 cm above the rain-snow line. The freezing level hovers around 1000 m. 60 to 80 km/h southwest ridgetop wind. Treeline temperature -2 °C. 

Thursday

Cloudy with 1 to 10 cm of snow. 20 to 30 km/h south ridgetop wind. Treeline temperature -7 °C. Freezing level falls to 500 m.

Friday

Cloudy with 10 to 20 cm of snow. 30 to 50 km/h southeast ridgetop wind. Treeline temperature -7 °C. Freezing level hovers around 500 m.

Saturday

Cloudy with 5 to 10 cm of snow. 25 to 40 km/h southeast ridgetop wind. Treeline temperature -7 °C. Freezing level hovers around 500 m.

Terrain and Travel Advice

  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
  • Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
  • Investigate the bond of the recent snow before committing to your line.

Avalanche Problems

Storm Slabs

+50 cm of storm snow and strong winds have built reactive slabs at higher elevations. Deeper deposits are expected in north and east facing terrain around ridgelines.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2.5
