Regions

Chic-Choc Mountains.

The snow is back! Pay attention to lee areas where snow accumulations will be more important. The ground remains close under this fresh snow, and natural traps may surprise you. This storm will bring different amount of snow, depending on where you are in Gaspésie. By filling out a MIN, you are helping us to get additional data!

Avalanche Summary

No new avalanche activity has been observed or reported. Please share your observations at [email protected], or with the Mountain Information Network.

Snowpack Summary

On Wednesday morning, 15 to 25 cm of snow, more in lee areas, could cover the thick refreezing crust. Despite the small amount of snow received in the last 24 hours, this crust remains an ideal bed surface. 10 to 15 cm of snow will be added to this layer during the day. Under this fresh snow, the ground and its natural dangers (stumps, fallen trees, rocks) are still very close and these traps, although not visible, could surprise you during your descent.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
