Regions

Chic-Choc Mountains.

In many places, the thickness of the snowpack has decreased in the Parc de la Gaspésie. Many rocks are now visible on descents. With the variability of snow surfaces (crust, hard-packed snow, windslabs) and current snow coverage, caution is advised.

Confidence

High

Avalanche Summary

One size 1 loose wet avalanche that run to ground was observed on Mount Albert, on an eastern aspect at about 600m elevation. The avalanche must have occurred within the last 24 hours.

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

Snowpack Summary

The dry snow line is at around 700m and we have received between 3 and 5 cm of new snow since Saturday. On sheltered eastern slopes above 700m, surface hoar has been buried under 3 to 5 cm of snow. We will continue our investigation on the other aspects over the next few days to assess the distribution of surface hoar.

Below 700m, there is between 5 and 10 cm of moist snow on the surface, which is likely to create a new crust layer.

The core of the snowpack is well consolidated, and resting on the December 30 combo of facetted grains and crust. Facetted grains and depth hoar are developing at the base of the snowpack.

Weather Summary

Synopsis: A major low-pressure system will pass southeast of the Gaspé Peninsula this week, bringing moderate to strong northwesterly winds and possibly a few snow showers.

Sunday evening and night: Cloudy. 2 to 3 cm of snow. Wind from the northwest at 30 to 50 km/h. Temperature cooling to a minimum of -8C.

Monday: Cloudy. Trace of snow. Wind 30 to 50 km/h from the northwest. Maximum -8C.

Tuesday: Alternating sun and cloud. Wind northwest 20 to 40 km/h. Maximum -10C.

Wednesday: Cloudy. 2 to 3 cm of snow. Wind northwest 20 to 40 km/h. Maximum -9C.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • Be cautious of buried obstacles especially below treeline.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.

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.
