Regions

Northwest Coastal, Boundary, Kitimat, Rupert, Shames, Stewart.

Investigate the bond of the new snow to the old.

Buried surface hoar has been reported in the northern part of the region, but observations are limited.

Confidence

Low

Avalanche Summary

No new avalanches have been reported since before last weekend.

Please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

Thursday's snowfall dropped around 10 cm onto surface hoar crystals. Observations are few and far between so it's unknown how widespread the surface hoar is.

Below that is a thick rain-crust, down 20 to 30 cm, from late last week.

The remainder of the snowpack is strong, with various hard layers and crusts.

Weather Summary

Thursday Night

Cloudy with 5 cm of snow in the north. 20 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Friday

Mostly cloudy. 10 km/h west then east ridgetop wind. Treeline temperature -4 °C.

Saturday

Cloudy with 5 to 10 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -7 °C.

Sunday

A mix of sun and cloud with 2 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -8 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be careful as you transition into wind-affected terrain.
  • Make observations and continually assess conditions as you travel.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.

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.
