Regions

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

Start small if you're poking into avalanche terrain on Sunday and be ready to dial back your terrain selection with any signs of instability.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.

Avalanche Summary

Early reports from Saturday's storm in the Whistler area showed ski cutting and explosives producing size 1 releases in ridgetop lees in the morning, with snow and wind ongoing.

Slabs formed at higher elevations, especially where wind loaded, will remain a concern for Sunday.

Snowpack Summary

Saturday's storm should leave us with 20 to 40 cm of windblown new snow above treeline, tapering to a rain-soaked surface below treeline.

Where new snow accumulated, it mostly buried a widespread thin crust, thickest on sun-exposed slopes. It may add to dry snow on the region's highest north-facing slopes.

Below the evolving surface, a wind-redistributed 15-50 cm of older snow, some moist and settled, some dry and faceted, sits on the thick late-January crust. A few areas are more problematic with only 5 cm of lower density faceted snow above the crust.

The mid and lower snowpack are well settled and strong.

Weather Summary

Saturday Night
Becoming partly cloudy as the storm finishes with about 5 cm of new snow above 1500 m. 20 to 50 km/h southwest ridgetop wind, easing. Treeline temperature falling to -3 °C as freezing level drops to 1200 m.

Sunday
Sunny. 20 km/h southwest ridgetop wind, easing a bit. Treeline temperature -2 °C. Freezing level 1300 m.

Monday
Becoming cloudy with flurries bringing up to 5 cm of new snow. 20 km/h south ridgetop wind. Treeline temperature -4 °C.

Tuesday
Cloudy with flurries continuing from overnight bringing 5 to 20 total cm of new snow. 10 to 30 km/h southwest ridgetop wind, easing. Treeline temperature -3 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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.
