Regions

Chic-Choc Mountains.

Weather models disagree on the amount of snow expected between Friday evening and Saturday evening. Be careful: the snow that falls after the rain episode may not adhere well to the old snow.

Confidence

Low

Avalanche Summary

Few observations in the field today. 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

Saturday morning, between 10 and 25 cm of new snow will cover wet snow and/or crust. New snow accumulation will be greatest at higher altitudes. Snow cover in the alpine is likely to have diminished considerably due to extreme southerly winds, rain and recent high temperatures.

The height of the snowpack varies between 100 cm and 200 cm.

Weather Summary

WEATHER FOR THE CRESTS AND SUMMITS OF CHIC-CHOCS

Friday evening and night: Snow, sometimes heavy. Accumulations of 10 to 15. Winds west, 20 to 40 km/h. Minimum -14 °C.

Saturday: Intermittent snow. Accumulation of 4 to 8 cm. Wind west, 40 to 60 km/h. Maximum -12 °C.

Sunday: Alternating sun and clouds. Accumulation of 3 to 5 cm. Northwest winds, 30 to 50 km/h. Maximum -10 °C.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
