Regions

Cariboos, Blue River, Clearwater, McBride, Premier, Quesnel, Clemina, North Monashee, Renshaw, Robson.

Cool temperatures decrease hazard. If a thick crust is present, large slab avalanches are unlikely.

Back off if you find moist or wet surface snow; large slab avalanches remain triggerable.

Confidence

Moderate

Avalanche Summary

On Tuesday, a size 2 natural persistent slab avalanche was reported on a south-facing slope at treeline. The widespread natural avalanche cycle up to size 3 continued while temperatures were warm through Monday.

Looking ahead, in areas where you find a thick surface crust, avalanche activity is unlikely.

Snowpack Summary

Above 1000 m, about 10 cm of new snow will likely overlie a firm crust. Expect a thick, supportive melt-freeze crust on the surface at low elevations.

Two layers of surface hoar and sun crust can be found in the top meter of the snowpack.

A thick and hard widespread crust, formed in early February, is buried about 70 to 130 cm deep. This crust has a layer of facets above it in many areas.

The snowpack below this crust is generally not concerning except in shallow alpine terrain.

Weather Summary

Thursday Night

Becoming clear. 20 km/h northwest ridgetop winds. Treeline temperatures -12 °C.

Friday

Mostly sunny. 15 km/h north ridgetop winds. Treeline temperatures -8 °C.

Saturday

Sunny. 20 km/h north ridgetop winds. Treeline temperatures -5 °C.

Sunday

Sunny. 15 to 30 km/h northeast ridgetop winds. Treeline temperatures -5 °C.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Avoid exposure to steep, sun exposed slopes, especially when the solar radiation is strong.

Problems

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
