Regions: Babine, Hudson Bay, Microwave-Sinclair, North Bulkley, South Bulkley, Telkwa.

Sunshine and light winds can make big lines appealing, but wind slabs continue to be found.Assess your line before committing, and consider sticking to sheltered terrain for better riding.

Avalanche Summary

Recent slab avalanche activity was noted in the microwave area yesterday. Field observations have been very limited, if you head out, please consider submitting and MIN.

The photo below shows a recent larger avalanche that stepped down from a smaller avalanche initiated in the gully above.

Snowpack Summary

In alpine and open treeline areas, 15 to 30 cm of wind-affected snow sits over a variety of surfaces including facets over a crust, old hard wind slabs, or surface hoar. The surface hoar is most likely to be found in sheltered areas at treeline and below.

Soft snow and good riding can still be found in wind-sheltered areas.

Another layer of weak, faceted crystals and a crust may be found buried 30 to 60 cm deep.

The lower snowpack is generally well-bonded and strong.

Weather Summary

Sunday Night

Clouds clearing overnight. East ridgetop wind, 15 to 30 km/h. Treeline temperature -22 °C.

Monday

Sunny. Southeast switching to northwest ridgetop wind, 5 to 15 km/h. Treeline temperature -15 °C.

Tuesday

Sunny. West ridgetop wind, 5 to 15 km/h. Treeline temperature around -8 °C.

Wednesday

Increasing cloudiness. Southwest ridgetop wind, 20 to 40 km/h. Treeline temperature -6 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be especially cautious as you transition into wind affected terrain.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Keep in mind that human triggering potential persists as natural avalanching tapers off.

Avalanche Problems

Wind Slabs

Wind slabs may step down to deeper layers triggering larger than expected avalanches.

Aspects: North, South, South West, West, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Persistent Slabs

Weak sugary facets overlying a crust or a layer of buried surface hoar may be susceptible to human triggers in isolated areas.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 2.5
