Microwave-Sinclair, North Bulkley, South Bulkley, South Bulkley, South Bulkley, Telkwa.

Avalanche danger will increase during the heat of the day. Use particular caution on sunny slopes and near cornices.

Avalanche Summary

We haven't received any recent reports of avalanche activity.

Please consider sharing your observations to the Mountain Information Network.

Snowpack Summary

A dusting of dry snow is found over a hard melt-freeze crust. This snow will melt with daytime warming. Old wind slabs may linger in lee terrain features near mountain tops.

Two weak layers that formed in February and March are found in the middle of the snowpack. These layers are currently dormant, but they could be triggered with a large load such as a cornice fall.

Weather Summary

Wednesday Night

Clear skies. 10 to 20 km/h south ridgetop wind. Treeline temperature -2 °C. Freezing level 1500 m.

Thursday

Mostly sunny. 10 to 20 km/h south ridgetop wind. Treeline temperature +5 °C. Freezing level 2100 m.

Friday

A mix of sun and cloud. 20 to 30 km/h southwest ridgetop wind. Treeline temperature +4 °C. Freezing level 1900 m.

Saturday

Mostly cloudy. 10 to 20 km/h west ridgetop wind. Treeline temperature +1 °C. Freezing level 1600 m.

Terrain and Travel Advice

  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.

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.
