Regions

Chic-Choc Mountains, Chic-Chocs.

Dial back your terrain choices as the storm intensifies. Snowfall and moderate wind will build larger and more reactive wind slabs in the afternoon.

Confidence

Moderate

  • We are uncertain due to the timing, track, and intensity of the incoming weather system.

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

By Wednesday evening, we may receive around 15 cm of new snow, which will overlay a widespread melt-freeze crust present on all aspects and at all elevations. Deeper deposits may be found on northerly aspects, while westerly aspects are mostly bare.

The remainder of the upper snowpack is composed of multiple crusts and moist snow. The mid and lower snowpack are well settled.

At mid-elevations, the average snowpack depth is around 110 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

Another low pressure system is expected to impact the Chic Chocs starting Wednesday afternoon. This system will bring heavy precipitation and strong to extreme wind.

Tuesday Evening and Night : Partly cloudy. Accumulation of 2 to 4 cm. 20 to 40 km/h northwest wind. Minimum -15°C.

Wednesday: Cloudy. 5 to 15 cm of snow starting in the afternoon. 10 to 30 km/h north wind in the morning switching to southeast in the afternoon. Maximum -9°C.

Thursday: Snow showers. 20 to 40 cm of snow.  40 to 90 km/h southeast in the morning and 15 to 35 km/h southwest wind in the afternoon. Maximum -2°C.

Friday: Mix of sun and cloud. 5 to 10 cm of snow. 20 to 35 km/h west wind. Maximum -14°C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Wind slabs are most reactive during their formation.
  • Carefully evaluate steep lines for wind slabs.

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.
