Regions

Cariboos, Blue River, McBride, Premier, Quesnel, Clemina, Kakwa, Renshaw, Robson.

Start in mellow terrain, and check if the fresh snow is sticking to the old surface.

Human triggered avalanches are more likely where the snow is deeper.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported.

If you are getting out in the backcountry, consider making a post on the MIN (Mountain Information Network).

Snowpack Summary

20-45 cm of fresh snow covers another 15-30 cm of soft, settling snow above 1500 m. Below that is a hard, frozen crust on all aspects and elevations, except on north facing slopes over 2000 m, where you'll find old, dense, wind-affected snow.

Below 1500 m, moist surfaces will start to get crusty or covered by snow as the freezing level drops.

A layer of weak faceted snow above a hard crust that formed in early February is buried about 50 to 120 cm deep. This layer is generally getting stronger, and is shielded by crusts above it. It has not produced any recent avalanches.

Weather Summary

Wednesday Night

Cloudy. Light snow 1 - 5 cm expected. Light to moderate southwest ridgetop wind. Freezing level dropping to valley bottom. Treeline low around -6 °C.

Thursday

Mostly cloudy. 1-5 cm of snow expected to near valley bottom. Light west or southwest ridgetop wind. Treeline temperature around -1 °C.

Friday

Mostly cloudy. 1-2 cm of snow expected. Light northeast ridgetop wind. Treeline high around -1 °C.

Saturday

Mostly sunny. No new snow expected. Light northeast ridgetop wind. Treeline high around 0 °C.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Choose simple, low-angle, well supported terrain without convexities.
  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
