Regions

Chic-Choc Mountains.

A LOW rating does not mean that there is no danger of avalanches. The fresh snow expected on Tuesday night could lead to localized avalanche problems, which you'll need to be aware of on your outings.

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

Conditions are highly variable in the alpine and at treeline (presence of rocks, ice and wind-blown snow). Above 900 m, 30 cm of recent, wind-affected snow lies on a generalized refreezing crust. Below the treeline, up to 50 cm of wet recent snow lies on the refreezing crust. The upper part of the snowpack, up to 80 cm deep, is moist. The middle of the snowpack consists of alternating well-consolidated snow and refreezing crust.

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

Weather Summary

WEATHER FOR THE CRESTS AND SUMMITS OF CHIC-CHOCS

A low pressure system brings a little snow.

Tuesday evening and night: Rain changing to snow. Accumulations of 4 to 7 cm. South wind, 15 to 25 km/h. Low -4. Freezing level at 500 m.

Wednesday: Light snow, changing to rain at lower altitudes. Light north-westerly wind. High +1. Freezing level at 800 m.

Thursday: Cloudy. Light north-westerly wind. High +2. Freezing level at 1100 m.

Friday: Alternating sun and cloud. Light north-westerly wind. High +3. Freezing level at 1250 m.

For more details, consult 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.
