Regions

Sea To Sky, South Coast Inland, Brandywine, Garibaldi, Homathko, Spearhead, Tantalus, Birkenhead.

Watch for changing conditions as you gain elevation and shift aspects.

Greatest concern is for higher elevations where rain may fall on recent, reactive storm snow.

Confidence

Moderate

  • We are uncertain due to variable freezing levels.

Avalanche Summary

Over the past 3 days, rider triggered slabs have been reported up to size 2, and explosives have produced larger avalanches.

Another round of avalanche activity is likely as rising temperatures and rain affect drier snow at higher elevations

Snowpack Summary

By Monday afternoon up to 30 cm of new snow may have fallen over wind affected surfaces at upper elevations from recent southwest winds. Rising temperatures and rain will affect the recent snow to around 1800 m.

A persistent weak layer sits below, present as crust and facets at treeline and above, and a combination of crust and surface hoar in sheltered features and lower elevations.

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

Sunday Night
Cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing level 1400 m.

Monday
Cloudy. 10 to 20 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -2 °C. Freezing levels rise to 2000 m over the day.

Tuesday
Mostly cloudy. 4 to 5 mm of precipitation as snow or rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2000 m.

Wednesday
Mix of sun and clouds. 1 to 3 mm of rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2500 m.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • As the storm slab problem worsens, the easy solution is to choose more conservative 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.
