Regions

Chic-Choc Mountains, Chic-Chocs.

The warm, sunny conditions forecast for Sunday could quickly weaken the surface of the snowpack, increasing the danger of small wet-loose avalanches and making cornices more fragile. Limit your time on steep, sunny slopes, especially if the surface snow becomes wet.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

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

In the alpine, a layer of 2 to 10 cm of relatively wet fresh snow lies on top of a hard crust formed by cycles of daytime thawing and night-time refreezing. Despite limited sunshine on Saturday, it is likely that south-facing slopes, as well as those at lower altitudes, were affected by the warmth and brief spells of sunshine. Alpine slopes are expected to refreeze overnight from Saturday to Sunday, before being influenced by the sun again on Sunday.

The snowpack continues to melt below the tree line.

At mid-mountain, the average snowpack depth is around 90 to 120 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

A high-pressure system will bring sunshine and warm weather on Sunday and at the start of the week☀️.

Saturday evening and night: Partly cloudy. North wind of 30–50 km/h, easing overnight. Low -2°C. Freezing level down to 350m.

Sunday: Generally sunny. North-westerly wind of 10 to 20 km/h. Maximum +4°C. Freezing level at 1,500m.

Monday: Sunny. Light south-westerly wind. Maximum +7°C. Freezing level at 1,700m.

Tuesday: Sunny. Light south-westerly wind. Maximum +11°C. Freezing level at 2,700m.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.

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.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
