Regions

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

High avalanche danger. Avoid avalanche terrain and exposure to overhead hazards like cornices and runout zones.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.
  • We are confident the snowpack will rapidly weaken with the forecast weather.

Avalanche Summary

No significant new avalanches have been reported since Friday.

Expect a widespread natural avalanche cycle to continue through the forecast period.

Snowpack Summary

45 to 90 mm of precipitation is expected to fall by the end of the forecast period. Freezing levels rise between 1800 and 2400 m. Expect wet, unstable snow below these elevations.

Below 2100 m, a widespread crust is buried 20 to 60 cm deep. The snowpack below the crust is generally well settled and has no significant layers of concern.

Weather Summary

Monday Night

Cloudy. 15 to 35 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1600 m.

Tuesday

Cloudy. 30 to 45 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1800 m.

Wednesday

Cloudy. 40 to 60 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1900 m.

Thursday

Cloudy. 35 to 70 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 1900 m.

Terrain and Travel Advice

  • Don't let storm day fever lure you into consequential terrain.
  • 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.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.

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.
