In sintesi

The recent, lighter snow that fell on Wednesday lies on top ofwind slabs. Avoid steep slopes and large areas prone to avalanches in steep terrain, and allow the snowpack to stabilize.

    Wind slabs are currently layered on top of one another in areas prone to snow accumulation. Covered by about 15 cm of fresh snow that fell on Wednesday, they may be harder to detect and remain reactive to skiers passing over them. This fresh snow could also trigger small avalanches of loose, dry snow where it has not been compacted.

    These slabs rest on a refrozen crust, providing an excellent sliding surface, and are particularly unstable on east-facing slopes. Their thickness generally ranges from 20 to 60 cm.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

No new avalanches reported or observed.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

A new sun crust formed on the surface on Tuesday on the sunny slopes. The fresh snow that fell on Wednesday (15 cm) could react on this crust.

The wind has significantly redistributed the recent snowfall. Between 20 and 50 cm of fresh snow lies on top of a widespread refreeze crust approximately 2 cm thick. A weak layer of faceted grains has developed on this crust on the eastern slopes and is reacting in tests at the tree line, and likely also in alpine terrain.

At mid-mountain, the average snowpack depth is approximately 120 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

Partly cloudy skies are expected throughout Thursday, due to a strong high-pressure system forming over the center of the province.

Wednesday evening and night: Snow. Accumulation of 2–3 cm. Northwest wind at 15 km/h. Low of -12 °C.

Thursday: Alternating sunshine and clouds. Northwest wind at 10–20 km/h. High of -3 °C.

Friday: Snow. Accumulation up to 25 cm. Southeast wind 20 to 50 km/h. High of -4 °C.

Saturday: Sunny. North wind 20 km/h. High of 1 °C.

Terrain and Travel Advice

  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.
  • Carefully evaluate steep lines for wind slabs.
