Regions

Chic-Choc Mountains.

The winds associated with the last storm have created a great spatial variability in the snowpack. Isolated instabilities may persist.

Watch for signs of instability such as whumphing or shooting cracks.

Confidence

Avalanche Summary

No new avalanche was reported or observed. If you go into the backcountry, thanks for sharing your observations at [email protected] or on the Mountain Information Network (MIN).

Snowpack Summary

The extreme winds from the last storm have redistributed the snow very unevenly. The eastern and southern aspects are generally exposed to the crust. On the lees aspects (North west to North East), wind-pressed pockets of dense snow are showing impressive accumulations, with up to 130 cm of snow overlying the New Year's crust. A layer of facets has been observed between this new snow and the crust. Below treeline, despite this latest storm, the hazard is generally below threshold.

Weather Summary

Synopsis: Expect cold temperature on Friday, before the storm on Saturday's.

Thursday evening and night: Cloudy. West winds from 50 to 60 km/h. Min -13C. Freezing level at valley bottom.

Friday: Mostly cloudy. 1-2 cm of snow. Northwest winds from 50-55 km/h. Max -19C. Freezing level at valley bottom.

Saturday: Cloudy. Snow starting in pm. Southeast winds increasing to 120 km/h. Max -3C.

Sunday: Cloudy. Light snow. Southeast winds from 45 to 55 km/h. Max -10C.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Watch for areas of hard wind slab on alpine features.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
