Regions

Coquihalla, Harrison-Fraser, Manning, Skagit.

Verify that conditions are safe before entering committing slopes & remain cautious when travelling on or under corniced ridges and sunny slopes.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported.

Observations have been extremely limited in this region, making it a good idea to verify conditions and frequently reassess as you travel.

Please share to the Mountain Information Network if you head into the backcountry.

Snowpack Summary

The snowpack is generally well-settled and strong, although dormant weak layers may still exist in some areas.

A typical spring diurnal cycle is underway. High freezing levels and strong sun transform the snow surface during the day into moist or wet snow, while cooling at night generally forms a crust. Lower elevations are melting out rapidly.

Weather Summary

Friday Night

Cloudy with possible periods of light rain to 2 mm. 35 to 40 km/h southwest ridgetop wind. Treeline temperature low +1 °C. Freezing level 3200 m, falling to 1700 m.

Saturday

Mostly sunny. 30 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level around 1700 m.

Sunday

Cloudy with 5 to 15 cm of new snow above 1400 m, rain below. 25 to 35 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level rising to 1500 m.

Monday

Mostly cloudy with 1 to 5 cm of snow above 1500 m, rain below. 10 to 20 km/h variable ridgetop wind. Treeline temperature -2 °C. Freezing level rising to 1600 m.

Terrain and Travel Advice

  • Periods of low danger may be a good time to increase your exposure.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.

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.

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.
