Regions

Chic-Choc Mountains, Chic-Chocs.

Without overnight freezing and due to the warm weather, the snowpack becomes less and less cohesive as the day goes on. It’s best to head out into the mountains early rather than late.

Confidence

High

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

Avalanche Summary

Small loose snow avalanches were observed on Tuesday in the alpine on sun-exposed slopes at Mont-Albert.

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

Snowpack Summary

In alpine terrain and at treeline, the snowpack is gradually transitioning toward an isothermal state. Below treeline, this process is complete, and you can easily sink up to your waist when you remove your travel equipment.

The snowpack is melting rapidly.

At mid-mountain, the average snowpack depth is around 80 to 110 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

The nice weather is gradually giving way to rain in the Chic-Chocs, ushering in a cooler start to May with temperatures below seasonal averages.

Wednesday evening and night: Cloudy. South wind 10 to 30 km/h. Low 0°C. Freezing level up to 2,200 m.

Thursday: Sun and clouds alternating. Southeast wind 30 to 50 km/h. High 10°C. Freezing level at 2,000 m.

Friday: Intermittent rain, 5 to 10 mm. Southeast wind 60 to 80 km/h. High 6°C. Freezing level at 2000 m.

Saturday: Rain showers clearing early in the morning. Northwest wind 10 to 40 km/h. High 4°C. Freezing level at 1000 m.

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.

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.
