Regions

Chic-Choc Mountains.

Stay away from slopes when surface snow becomes moist or wet with rising temperatures and solar input.

Confidence

Moderate

Avalanche Summary

No new avalanches observed or reported.

If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

Below treeline and possibly up to treeline, a sun crust is present on sun-exposed slopes. In areas sheltered from the wind, between 5 and 30 cm of more or less dense snow can be found on top of a refreezing crust.

In general, west- and north-facing slopes, whether in alpine zones or at treeline, are either bare with exposed rock, or covered with a crust. Snowpack thickness varies between 100 cm and 200 cm.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.

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.
