Regions

Chic-Choc Mountains, Chic-Chocs.

Storm slabs take time to stabilize. Stay alert for signs of instability and avoid steep slopes and loaded areas. Descents below tree line will be excellent and remain the safest option.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

Signs of instability observed in leeward areas on small reliefs: cracks and the detachment of storm slabs.

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

Snowpack Summary

The fresh snowfall, which could reach up to 20 cm, lies on a variety of surfaces.

Sunny slopes will warm up on Saturday. A sun crust formed on the surface of sunny slopes on Thursday. Beneath it, about 15 cm of snow that fell on Wednesday lies on top of a sun crust that formed on Tuesday.

On northern aspects, between 20 and 50 cm of snow ranging from loose to dense lies on a widespread refreeze crust approximately 2 cm thick. A weak layer of faceted grains has developed on this crust on north-to-east-facing slopes and is reacting in tests at the tree line and in alpine terrain.

At mid-mountain elevations, the average snowpack depth is approximately 140 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

The storm will end early Saturday morning, giving way to a high-pressure system that will bring sunny weather on Saturday.

Friday evening and night: Cloudy. Wind from the southeast shifting to the northeast at 15 km/h. Low of -10 °C.

Saturday: Sunny. North wind at 20 km/h with gusts up to 40 km/h. High of -2 °C.

Sunday: Mixed precipitation. Up to 25 cm of snow. Freezing rain late in the afternoon. South wind at 50 to 80 km/h. High of 0 °C. Freezing level 250 m by late afternoon.

Monday: Cloudy. Up to 3 cm of snow possible. West wind 20 to 40 km/h. High of -4 °C.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be aware of the potential for human triggerable storm slabs at lower elevations, even on small features.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.

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.
