Regions

Chic-Choc Mountains.

A LOW rating does not mean there is no avalanche danger. Just a few hours of afternoon sunshine can quickly weaken the surface snow and create a wet loose avalanche problem.

Confidence

Moderate

Avalanche Summary

No new avalanches have been observed or reported.

If you are out and about in the hinterland, please share your observations with the RIM ( Réseau d'Information en Montagne ).

Snowpack Summary

Before Tuesday night's refreeze, about 30 cm of wind, rain, and warmth compacted snow was observed in the most loaded alpine areas, resting on a widespread melt-freeze crust. Below the treeline, up to 50 cm of recent moist snow covered the same crust.

Conditions vary greatly in alpine terrain and near the treeline, with exposed rocks, ice, and areas of deeper accumulation.

The mid-pack is well consolidated.

At mid-mountain, the snowpack depth ranges from 80 to 170 cm.

Weather Summary

WEATHER FOR THE RIDGES AND SUMMITS OF THE CHIC-CHOCS

A high-pressure ridge is bringing relatively stable weather conditions ahead of a low-pressure system expected on Saturday, which carries a lot of uncertainty.

Wednesday evening and night: Cloudy with light rain or snow. Light northwesterly wind. Low of -5 °C. Freezing level in the valley.

Thursday: Cloudy. Light north wind. High of +1 °C. Freezing level at 1100 m.

Friday: Cloudy with light snow in the morning. Light northwesterly wind. High of +2 °C. Freezing level at 1200 m.

Saturday: Wet snow or rain. 15 to 20 cm, possible. Southeasterly wind at 10 to 20 km/h. High of -1 °C. Freezing level at 900 m.

For more details, check the Chic-Chocs alpine weather forecast.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

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.
