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

Several wet loose avalanches were reported over the weekend, involving the most recent storm snow over the robust crust.

We expect wet loose avalanche activity to continue with sunny skies in the forecast.

Snowpack Summary

Up to 30 cm of heavy, moist snow has accumulated above 1700 m. At treeline and below the upper snowpack is saturated.

Below this, a variable (robust to breakable) crust sits over a facet layer at treeline and above. In sheltered features a surface hoar layer may have survived the recent warm temperatures and rain.

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

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

Weather Summary

Tuesday Night
Partly cloudy. 1 to 2 mm of rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2700 m.

Wednesday
Sunny. 50 km/h southwest ridgetop wind. Treeline temperature 7 °C. Freezing level 3100 m.

Thursday
Sunny. 30 km/h southwest ridgetop wind. Treeline temperature 8 °C. Freezing level 3300 m.

Friday
Mostly sunny. 40 km/h southwest ridgetop wind. Treeline temperature 5 °C. Freezing level 2900 m.

Terrain and Travel Advice

  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.

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.
