Regions

Sea To Sky, Brandywine, Garibaldi, Homathko, Spearhead, Tantalus.

Large, overhanging and, fragile cornices are primed for triggering with high freezing levels and sunny skies.

Stay well back from the edge of ridges, and slopes threatened by cornices.

Confidence

Moderate

  • We are uncertain due to variable freezing levels.

Avalanche Summary

On Tuesday, numerous size 1 to 1.5 wet loose avalanches were reported.

On Monday, several natural and human triggered cornice releases were reported.

Numerous human-triggered size 1 to 2 storm slab avalanches were reported on Monday.

Cornices will remain reactive with the continued elevated freezing levels.

Snowpack Summary

Clear skies overnight has developed a surface crust over moist snow.

Above 1800 m recent snow is rapidly settling over a crust and facets. In open terrain windward features are scoured back to this crust, and is wind affected in lee features.

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

Cornices are reported to be large and looming. Be mindful of them overhead or when travelling on ridge tops.

Weather Summary

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

Thursday
Sunny. 30 km/h southwest ridgetop wind. Treeline temperature 9 °C. Freezing level 3400 m.

Friday
Sunny. 40 km/h south ridgetop wind. Treeline temperature 4 °C. Freezing level 2600 m.

Saturday
Mostly cloudy. 30 to 40 cm mixed precipitation turning to snow at treeline. 60 km/h south ridgetop wind. Treeline temperature 0 °C. Freezing level 1700 m.

More details can be found in the Mountain Weather Forecast.

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.
  • Be careful as you transition into wind-affected terrain.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.

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.
