Regions

South Coast, Powell River, North Shore, Sky Pilot, Tetrahedron.

Recent snow will likely be sensitive to strong sun on Sunday.

Confidence

Moderate

Avalanche Summary

Reports have been very limited during the recent stormy period. Several wet loose avalanches were reported across the region over the past few days, generally in the small (size 1-1.5) range.

We expect recently accumulated storm slabs will be reactive on Sunday.

Snowpack Summary

Above 1000 m, 30 to 50 cm of snow from Saturday blankets a developing crust over a rain-soaked snowpack. At wind-exposed elevations, southerly wind has likely redistributed the recent snow into deeper deposits on northerly aspects.

At lower elevations, the rain-saturated snowpack tapers quickly with elevation.

For more details on the North Shore snowpack, check out this video from Friday.

Weather Summary

Saturday

Mostly clear. 10 to 30 km/h south ridgetop winds. Treeline temperature 0 °C. Freezing level rising to 1700 m.

Sunday

Sunny. 30 to 40 km/h southeast ridgetop winds. Treeline temperature +2 °C. Freezing level rising to 1800 m.

Monday

Cloudy with 5 to 15 cm of snow. 20 to 40 km/h variable ridgetop winds. Treeline temperature -3 °C. Freezing level 1500 m.

Tuesday

A mix of sun and cloud. 20 to 40 km/h northwest ridgetop winds. Treeline temperature -3 °C. Freezing level around 1400 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be alert to conditions that change with elevation and sun exposure.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.

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.
