Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Temperatures and danger ratings are falling.

Watch for changing conditions as you gain elevation, dry snow may be found in the alpine and large cornices are fragile.

Confidence

Moderate

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

On Sunday, wet loose activity was reported at all elevations to size 2. In addition, several wind slab avalanches were reported.

As temperatures cool, wet loose activity is unlikely. If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Snowpack Summary

Overnight cooling will likely form a widespread surface crust. Beneath the crust, the upper snowpack will remain moist, gradually refreezing as temperatures drop.

Dry snow remains on the highest, north facing slopes spared from the warming. This sits over a hard crust below about 1900 m, and old wind-affected snow at upper elevations.

Two older crusts exist 1-1.5 m deep. While these are not a concern under cooler tempeatures, large cornice falls or the next wave of heat may wake these layers up.

Weather Summary

Monday Night
Mostly clear skies. 40 km/h west ridgetop wind. Treeline temperature -4 °C.

Tuesday
Sunny. 30 km/h northwest ridgetop wind. Treeline temperature -6 °C. Freezing level 1000 m.

Wednesday
Sunny. 20 km/h northwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1200 m.

Thursday
Sunny. 20 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1500 m.

Terrain and Travel Advice

  • 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

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
