Regions

Cariboos, Blue River, McBride, Premier, Quesnel, Clemina.

Use safe travel habits, and constantly assess conditions as you travel.

Both rain and snow are expected. The sun should be less intense, but freezing levels remain elevated.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported.

Please consider submitting your observations to the MIN if you head to the backcountry.

Snowpack Summary

By the end of the day on Tuesday, above 1700 m, expect 25-50 cm of soft snow on the surface. Under this, weak, feathery surface hoar crystals sit on faceted or wind-affected snow on northerly alpine terrain and a hard melt-freeze crust elsewhere.

Below 1700 m, expect the snow surface to be moist due to light rain.

A widespread crust that formed in early February is buried anywhere from 80 to 150 cm deep. This crust has a weak layer of faceted grains above it that are slowly strengthening. This layer is currently dormant.

The remainder of the snowpack is settled.

Weather Summary

Monday Night

Cloudy. Light rain expected. 0-2 cm of snow above 1700 m. Light to moderate southwest ridgetop wind. Treeline temperature around 1 °C.

Tuesday

Cloudy. Light rain expected, 5-10 cm of snow above 1700 m. Light to moderate southwest ridgetop wind. Treeline temperature around 1 °C.

Wednesday

Mostly cloudy. Light to moderate precipitation continues as the freezing level drops to valley bottom. It could add up to 15-20 cm of snow at high elevations. Light to moderate southwest ridgetop wind. Treeline temperature around -5 °C.

Thursday

Mostly cloudy. No new snow expected. Light northeast ridgetop wind. Treeline high around -5 °C.

Terrain and Travel Advice

  • Don't be too cavalier with decision making, storm slabs may remain sensitive to human triggering.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
