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

A new surface crust has developed on sunny slopes. In areas sheltered from the wind, there is between 5 and 30 cm of new snow on top of a refreezing crust.

As a general rule, west- and north-facing slopes, both in the alpine and at treeline, are bare or crust-covered. Snowpack thickness varies between 100 cm and 200 cm.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • 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.

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.
