Regions

Coquihalla, Harrison-Fraser, Manning, Skagit.

Freezing levels are forecasted to soar above 3000 m, keeping avalanche hazard elevated.

Travel in avalanche terrain is not recommended.

Confidence

Low

  • Uncertainty is due to how the snowpack will react to the forecast weather.

Avalanche Summary

Several size 2 wet loose avalanches were reported on Monday.

Rain has tapered, but warm temperatures and high freezing levels will keep human triggering of wet loose avalanches possible.

Snowpack Summary

Rain or wet snow above 2000 m from the past 24 hours has saturated the upper snowpack and has rapidly settled 50 to 80 cm of storm snow from last week. High freezing levels will keep the surface snow moist throughout the day.

The mid-December crust is 100 to 250 cm deep. This crust is 30 cm thick and well-bonded to the snow above.

Weather Summary

Monday Night
Cloudy. 5 to 25 mm of rain at treeline. 70 km/h west ridgetop wind. Treeline temperature 3 °C. Freezing level 2600 m.

Tuesday
Mix of sun and cloud. 1 mm of rain at treeline. 40 km/h west ridgetop wind. Treeline temperature 4 °C. Freezing level 3400 m.

Wednesday
Mostly sunny. 50 km/h west ridgetop wind. Treeline temperature 5 °C. Freezing level 3200 m.

Thursday
Sunny. 20 km/h north ridgetop wind. Treeline temperature 3 °C. Freezing level 2900 m.

Terrain and Travel Advice

  • Keep in mind that the high density of wet avalanches can make them destructive.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

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.
