Avalanche Québec,
Avalanche Canada
⚠️A special avalanche warning is issued for the northern coastline of Haute-Gaspésie.
There is a lot of snow available in the mountains to form new wind slabs.
Look for wind-sheltered terrain below the tree line where you can avoid wind slabs and find excellent snow conditions.

Avalanche Summary
No new avalanches were observed or reported.
If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).
Snowpack Summary
In wind-sheltered areas, the new snow (25 to 30 cm) has accumulated on the existing snow layer in the mountains, forming up to 40 cm of snow resting on a thin, brittle crust. On sunny slopes, the crust is thicker and can extend up to 700 m.
The wind has altered the snowpack in the alpine zone, creating significant variability: some areas are bare, others compacted or eroded, while some have accumulated new snow.
The middle of the snowpack is well consolidated, resting on a layer of faceted grains that are rounding.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- Seek out sheltered terrain where new snow hasn't been affected by wind.
Problems
Wind Slabs
Following the storm, there is a lot of snow available for transport in the mountains. The northwest wind will load this snow on the leeward side, forming new reactive wind slabs under the ridges, alpine convexities, and in areas laterally loaded near the tree line.
Aspects: North East, East, South East, South.
Elevations: Alpine, Treeline.
