Regions

Chic-Choc Mountains, Chic-Chocs.

Strong sunshine and warm temperatures will cause the surface snow to become unstable, increasing the risk of small wet loose snow avalanches, especially during the warmest part of the day and on solar aspects. Keep an eye on changing conditions.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

No new avalanches have been observed or reported.

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

Snowpack Summary

The snowpack on sunny slopes (especially south and southwest-facing) will become unstable. Warm temperatures and solar radiation will significantly reduce the depth of the snowpack, increasingly exposing surface features.

At mid-mountain elevations, the average snow depth is approximately 135 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

Friday evening and night: Partly cloudy. Wind from the north shifting to the south at 20 km/h. Low of -8 °C.

Saturday: Sunny. Wind from the south at 10 to 50 km/h. High of 8 °C. Freezing level at 3,000 m.

Sunday: Rainy, with up to 10 mm of accumulation, then snow overnight, with up to 10 cm of accumulation. South wind 30 to 60 km/h. High of 6 °C. Freezing level dropping from 3,000 to 300 m throughout the day.

Monday: Partly sunny. West wind 20 to 40 km/h. High of -6 °C.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
