Regions

South Coast, North Shore, Sasquatch, Sky Pilot, Tetrahedron, Coquihalla, Harrison-Fraser, Manning, Skagit.

There's still snow up there if you aren't one to let cloudy skies and rain stop you! Be ready to manage variably crusty or isothermal snow and lingering cornices if you head out.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

A cornice failure was observed near the Lions on the North Shore at around noon on Monday, believed to have failed within 12 hours of that time. Check out the report HERE.

Otherwise, no recent avalanches have been reported and little activity is expected under current conditions.

Observations are starting to taper off in many regions. If you get out into the backcountry, post a MIN!

Snowpack Summary

Cloud and light rain will work against crust recovery Friday night, keeping the snowpack a bit closer to an isothermal state Saturday. This follows recent melt-freeze cycles and more inviting travel conditions atop the region's well settled snowpack. Rain should finally affect the bits of dry snow hiding on our highest north-facing slopes.

Minimal forecast rain doesn't promise much change, but travelers should still watch for isothermal conditions. Other than making travel difficult, wet loose avalanche danger also develops when this condition is in play, a counterpoint to slip-and-fall hazards when the surface is frozen.

The snowpack is diminishes rapidly below 1000 m and on solar aspects.

Weather Summary

Friday Night
Partly cloudy with scattered showers, less than 1 mm. 10 km/h southwest ridgetop wind. Treeline temperature 8 °C. Freezing level 2700 m.

Saturday
Cloudy with rain, 5 to 9 mm, becoming wet alpine flurries bringing less than 5 cm of alpine snow. 10 km/h southwest ridgetop wind. Treeline temperature falling from 5 °C to 1 °C. Freezing level dropping from 2500 m to 1700 m.

Sunday
Mostly cloudy with scattered showers, 1 to 3 mm. 10 km/h west ridgetop wind. Treeline high temperature 6 °C. Freezing level to 2400 m.

Monday
Cloudy with light rain, 3 to 5 mm, after 2 to 8 mm overnight. Possible trace of new snow to alpine. 20 km/h southwest ridgetop wind, increasing. Treeline temperature 2 °C. Freezing level 1800 m.

Terrain and Travel Advice

  • Cornices often break further back than expected; give them a wide berth when traveling on ridgetops.
  • Keep in mind that the high density of wet avalanches can make them destructive.

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.
