Regions

Northwest Coastal, Boundary, Stewart, Kispiox, Ningunsaw.

Hard wind slabs may persist at all elevations under ongoing cold, windy conditions and may show few, if any, warning signs before being triggered.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

Natural avalanche activity has decreased significantly since earlier this week, when strong northeast winds triggered a widespread natural avalanche cycle at treeline and above. However, human-triggered wind slabs remain possible.

Be sure to post your observations to the MIN if you get out!

Snowpack Summary

Snow surfaces have been heavily wind-affected in the alpine and in exposed terrain at treeline and below. Windward slopes are scoured down to old crusts or sastrugi, while leeward slopes have been heavily loaded, forming firm wind slabs.

In isolated, wind-sheltered terrain, 20 to 60 cm of snow may sit atop a crust and/or surface hoar, primarily at treeline and below.

A January crust with associated facets is buried roughly 100 to 200 cm below the surface. Below, the remainder of the snowpack is generally well settled and well bonded.

Weather Summary

Thursday Night
Mostly cloudy. Trace amounts of snow. 30 km/h west ridgetop wind. Treeline temperature -14 °C.

Friday
Mix of sun and clouds. Trace amounts of snow. 10 km/h south ridgetop wind. Treeline temperature -13 °C.

Saturday
Mix of sun and clouds. Trace amounts cm of snow. 30 km/h east ridgetop wind. Treeline temperature -13 °C.

Sunday
Mostly cloudy. Up to to 5 cm of snow. 40 km/h southeast ridgetop wind. Treeline temperature -15 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Approach lee and cross-loaded slopes with caution.
  • Outflow winds may form wind slabs at all elevations.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
