Beginning of the season for the Avalanche Quebec team and beginning of the season in the mountains!

Although skiing is possible, the generalized crust and barely hidden obstacles make travel perilous.

This will make for a good base!

Snowpack Summary

On our first mountain outing of the season at Hog's Back Mountain, we noticed a widespread crust on all slopes and altitudes. It is about 3 to 4 cm thick, it breaks under the weight of a skier and makes the descent rather unpleasant. We have no observations above 830 meters for the moment, but we strongly suspect that the rain has also affected the highest peaks of the Chic-Chocs. The snowpack height is very variable, ranging from a few centimeters to 80 centimeters in areas of maximum accumulation. It is early season and conditions are still marginal. There is not enough snow to cover most of the buried obstacles. The crust makes travel difficult and falls potentially dangerous.

Weather Summary

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Wind slabs may be poorly bonded to the underlying crust.

Problems

Wind Slabs

An icon showing Wind Slabs

The light snow forecast for Thursday night (if it materializes ...) will be carried by strong to extreme winds and could form wind slabs, especially below alpine ridges, in gullies and in cross loading areas. These will rest on a crust that could potentially form an excellent sliding plane.

Aspects: East, South East, South.

Elevations: Alpine, Treeline.
