Regions

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

Hazard will increase throughout the day. Avoid avalanche terrain and exposure to runout zones.

Confidence

High

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

Avalanche Summary

On Friday, evidence of a natural wind slab cycle up to size 2.5 was observed in the alpine from the mid-week wind event.

This MIN from Friday describes whumphing and remote-triggering a wind slab from 30 m away on a convex slope at treeline.

Expect avalanche activity to increase throughout the day.

Snowpack Summary

New snow overlies extensively wind-affected surfaces at upper elevations and possibly sun crust on steep solar aspects.

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

Sunday Night

Cloudy. 10 to 15 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Monday

Cloudy. 30 to 35 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Tuesday

Cloudy. 40 to 50 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C.

Wednesday

Cloudy. 35 to 50 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Don't let storm day fever lure you into consequential terrain.
  • 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.
