Regions

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

Watch for changing conditions as you shift aspects and elevations.

Where dry snow exists, you may find fresh wind slabs.

Confidence

Moderate

Avalanche Summary

Recent avalanche activity has been limited to small wet loose avalanches from steep terrain.

Snowpack Summary

Above 1000 m, 30 to 50 cm of moist, settling snow sits over a crust. In exposed terrain, southerly winds have 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

Monday Night

Mostly cloudy with possible flurries. 20 to 30 km/h northwest winds at ridgetop. Freezing level 1300 m.

Tuesday

A mix of sun and cloud. 20 to 30 km/h northwest ridgetop winds. Treeline temperature +4 °C. Freezing level around 1600 m.

Wednesday

Mostly cloudy. 10 to 20 km/h variable ridgetop winds. Treeline temperature +1 °C. Freezing level around 1200 m.

Thursday

Clear skies 30 to 40 km/h northeast ridgetop winds. Treeline temperature +5 °C. Freezing level around 1700 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
