Overnight freezing and for part of the day Friday promotes the formation of a crust at the surface, which will make it difficult to travel in the mountains.

Don't forget your crampons and ice axes!

Snowpack Summary

The return of the freezing level at the valley bottom during the night and for part of the day will form a melt-freeze crust on the surface, which may make travel conditions difficult.

In general, the rapid melting of the snowpack in recent days has exposed the ground, primarily at and below the treeline. Below the treeline, snow conditions are now minimal.Snowpack heights range from 10 cm (valley) to 105 cm (mid-mountain).

Weather Summary

Forecast for the Chic-Chocs ridges and summits.

Synopsis: A ridge of high pressure is gradually moving over the region to bring generally clear weather for the next few days.Thursday evening and night: Partly cloudy, no precipitation, northeasterly winds 20 to 30 km/h, minimum -4 C, freezing level at valley bottom.

Friday: Increasing cloudiness, possibility of light precipitation at the end of the day, northerly winds 10 to 20 km/h, maximum +3 C, freezing level at 1000 m.

Saturday: Sunny, no precipitation, southeasterly winds 10 to 20 km/h, maximum +6 C, freezing level at 2500 m.

Sunday: A mix of sun and cloud, no precipitation, southeasterly winds 30 to 40 km/h, maximum +4 C, freezing level at 2300 m.For more details, see the Chic-Chocs alpine forecast.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Caution around slopes that are exposed to cornices overhead.

Avalanche Problems

Cornices

Spring weather is favorable to cornices falls. Even a small cornice can be destructive and harmful. As they are unpredictable, be sure to stay well away from them at all times.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1 - 2.5
