Regions

Chic-Choc Mountains.

👉 ATTENTION - VALID FOR MONDAY, APRIL 1st TO WEDNESDAY, APRIL 3rd 👈

Without a surface crust that support a person's weight, consider the snowpack beneath your feet to be unstable.

Avalanche Summary

No avalanche activity has been observed or reported in the past 24 hours.

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

Snowpack Summary

In the alpine, 5 to 10 cm of dry, low-density snow is covering the crust created during the last storm. At and below treeline, the cold nights ahead will cool the top of the snowpack, forming a crust on the surface. As temperatures will approch 0C during the day on Tuesday and Wednesday, a slight change in the forecast could result in the softening of the surface at some elevations.

The rest of the snowpack is generally wet to the ground, which can weaken deeper layers in the snowpack.

Weather Summary

Synopsis : Temperatures will oscillate with the freezing point on Tuesday and Wednesday, making snow, and avalanche, conditions variable.

Monday evening and night: Clear sky. Northwest winds from 30 to 40 km/h. Minimum -8C. Freezing level at valley bottom.

Tuesday: Increasing clouds around mid-day. Trace of snow. Northeast winds around 30 km/h. Max 0C. Freezing level at valley bottom.

Wednesday: Cloudy. Trace of snow. Northeast winds from 30 to 40 km/h. Max -1C.

Thursday: Cloudy. Snow beginning late pm. East winds from 65 to 70 km/h. Max. -6C.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Carefully evaluate steep lines for wind slabs.
  • Adjust your travel plans accordingly to the changing conditions of elevation and time of day.

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.

Wet Slabs

Wet Slab avalanches are the release of a cohesive layer of snow (a slab) that is generally moist or wet when the flow of liquid water weakens the bond between the slab and the surface below (snow or ground). They often occur during prolonged warming events and/or rain-on-snow events. Wet Slabs can be very unpredictable and destructive.
