Lo esencial

We are uncertain about how much snow we will receive by Tuesday evening. The greater the accumulations, the more pronounced the wind slab problem will be. Travel cautiously and avoid areas where snow has been deposited by the wind.

    New wind slabs may form on east through west aspects with incoming snow and winds favorable for transport. The size of these wind slabs will depend on how much snow is received. These new wind slabs will form on top of older, more stubborn slabs that are still reactive in stability tests. This means that a small surface avalanche could step down and trigger a more deeply buried wind slab. In addition, a new sun crust formed on south-facing aspects on Sunday, providing an excellent sliding surface for newly formed wind slabs.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

No new avalanches have been observed or reported.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Between 5 and 10 cm of new snow are expected overnight Monday into Tuesday. In alpine terrain and at treeline, this snow will fall on a variety of surfaces: soft snow, old wind slabs, hard snow, sun crusts, or rocky surfaces.

Below treeline, there is generally 15 to 25 cm of soft snow resting on a progressively denser snowpack.

In the Mines Madeleine area, as well as in some locations on Ernest-Laforce, a layer of large rimed grains is buried beneath 20 to 50 cm of wind slab. This weak layer is one to watch on east through west aspects.

The average snowpack depth at mid-mountain is approximately 110 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS
A storm tracking across Newfoundland could bring us a few centimeters of snow by Tuesday evening.

Monday evening and overnight: Snow. Accumulation of 5 to 10 cm. Northeast winds 40 to 60 km/h. Low −10°C.

Tuesday: Snow. Accumulation of 2 to 4 cm. North winds 40 to 50 km/h. High −9°C.

Wednesday: Mainly cloudy. Light snow accumulation early in the morning. South winds 10 to 20 km/h. High −8°C.

Thursday: Snow. Accumulation of 3 to 5 cm. Southwest winds 10 to 20 km/h. High −5°C.

Terrain and Travel Advice

  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.
  • Wind slabs are most reactive during their formation.
  • If triggered, wind slabs may step down to deeper layers, causing larger avalanches.
