Weather Forecast

Tonight, expecting some isolated flurries, with little accumulation. Alpine temperature: Low -11 C, with light SW winds.

Friday, periods of snow with accumulatiuon ~10-15cms over the day. Temperature, High: -5 °C and moderate ridgetop wind SW: 25 km/h gusting to 55 km/h.

Snowpack Summary

Light precipitation and winds over the day. 15-25cm of un-compacted snow over a firm mid-pack with facets and depth hoar lingering near the ground. Mid-December persistent layers, including SH, and SH/FC combos can be found down 25-40cm but, only in isolated and sheltered locations, and almost exclusively in the Icefields region.

Avalanche Summary

No new avalanches observed. Forecasting field team finished off the last of the available fresh tracks in the Churchill slide paths with no instabilities to report.

Make your field trip observations count! Share them with the local outdoor adventure community on the Mountain Information Network from Avalanche Canada.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Saturday

Avalanche Problems

Persistent Slabs

In the alpine hard slabs sit overtop of facets. Dec 14th surface hoar to 6mm can be found in sheltered locations up to 2200m.

  • Whumphing, shooting cracks and recent avalanches are all strong indicators of an unstable snowpack.
  • Be aware of the potential for avalanches due to buried surface hoar in isolated areas.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5

Deep Persistent Slabs

Be cautious of thick to thin snowpack areas being likely trigger locations. The persistent slabs have the potential to step down to the weakness at the base of the snowpack.

  • Use caution in thin snowpack areas.
  • If triggered the wind slabs may step down to deeper layers resulting in large avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3.5
