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

Snow and rain from fluctuating freezing levels has buried previously wind affected surfaces.

Above 1800 m roughly 40 cm of moist snow sits over a crust and facets at treeline and above. In open terrain windward features are scoured back to this crust, and a wind slab can be found 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

Tuesday Night
Partly cloudy. 10 mm of rain at treeline (highest amounts in the north of the region). 100 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2400 m.

Wednesday
Sunny. 90 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2700 m.

Thursday
Sunny. 60 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2800 m.

Friday
Sunny. 50 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 2400 m.

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.

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.

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
