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

If there is no crust on the surface, triggering a persistent slab may be possible.

Most likely on high, north facing terrain in the alpine.

Confidence

Low

Avalanche Summary

A large avalanche was reported in the Evelyn area on a northeast aspect on Saturday. Check out the details in this MIN.

Snowpack tests continue to show reactivity on buried weak layers, but it's getting hard to pinpoint where they are a problem.

Read a great report from the field team here.

Snowpack Summary

10 to 15 cm of recent snow covers variably wind-affected snow in open terrain at upper elevations. A crust is found up to 2000 m and higher on solar slopes.

Below 1100 m the snowpack is wet and unconsolidated.

Two layers of currently exist in the mid-snowpack.

  • A layer of surface hoar that formed in early March can be found at a depth of 40 to 70 cm.

  • A layer of facets, surface hoar, and/or a crust from mid-February is buried 60 to 120 cm deep.

The remainder of the snowpack is well consolidated.

Weather Summary

Tuesday Night

Partly cloudy. 30 to 40 km/h northwest ridgetop wind. Treeline temperature -7 °C.

Wednesday

Mostly sunny. 10 to 20 km/h north ridgetop wind. Treeline temperature 0 °C. Freezing level 1800 m.

Thursday

Mostly sunny. 15 km/h northwest ridgetop wind. Treeline temperature +5 °C. Freezing level 3100 m.

Friday

Mostly cloudy with 5 to 10 cm of snow. 20 to 40 km/h west ridgetop wind. Treeline temperature +1 °C. Freezing level 2800 m in the morning, falling to 1500 m by the end of day.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be aware of the potential for large avalanches due to buried weak layers.
  • Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
  • Small avalanches can have serious consequences in extreme terrain. Carefully evaluate your line for slabs before you commit to it.

Avalanche Problems

Persistent Slabs

Triggering may still be possible where there is no crust on high alpine slopes. Consider if the risk is worth the reward, it's difficult to predict where and when this problem will be reactive.

Aspects: North, North East, East, North West.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 2 - 3
