Regions

Coquihalla, Harrison-Fraser, Manning, Skagit.

Heightened avalanche conditions caused by high freezing levels and clear sunny skies.

Use extra caution in steep, solar-facing terrain and be aware of overhead hazards like cornices.

Confidence

Moderate

  • We are uncertain due to rapidly changing freezing levels.

Avalanche Summary

No new avalanches have been reported in the area.

Snowpack Summary

Above 1700 m the snow is settling rapidly. At treeline and below the upper snowpack is saturated, with a variable surface crust.

Below this, a variable (robust to breakable) crust sits over a facet layer at treeline and above. It is unlikely that surface hoar remains, but may be found in sheltered features upper treeline.

The mid/lower snowpack is generally well settled and strong.

Snowpack depth ranges between 100 to 250 cm at treeline elevations.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

Problems

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
