Snowpack Summary
In the alpine, from 5 to 10 cm of low-density snow overlies on the crust left by the last storm. Snow cover is still minimal, but some couloirs and depressions have a slightly deeper snowpack. The new snow may cover some natural obstacles, but these remain close to the surface. Many areas at treeline and below are covered only by a thin layer of snow, which is why the index is below threshold for these elevation bands. Overall, the snowpack varies from 5 to 40 cm.
Weather Summary
Synopsis: North winds, combined with the unfrozen Saint-Lawrence, will favor orographic lifting. A few more centimetres can be expected.
Saturday evening and night: Cloudy. 1 to 2 cm of snow. North winds increasing to 50 km/h. Min. -10C.
Sunday: Cloudy. 1 to 3 cm of snow. Northwest winds from 45 to 50 km/h. Max. -13C.
Monday: Alternating sun and clouds. Northwest winds from 35 to 40 km/h. Max. -13C.
Tuesday: Cloudy. 2 to 3 cm of snow. Winds from 40 to 45 km/h from the west. Max. -13C.
Terrain and Travel Advice
- Avalanche danger is often elevated in alpine gullies where snow has accumulated.
- Wind slabs are most reactive during their formation.
- Fresh wind slabs will likely form throughout the day, diligently watch for changing conditions.
