Microwave-Sinclair, North Bulkley, South Bulkley, South Bulkley, South Bulkley, Telkwa.

6 AM UPDATE: New snow will likely be reactive to riders so manage your exposure to avalanche terrain.

Confidence

Moderate

Avalanche Summary

There have been no new avalanche observations since Thursday when a small (size 1) wind slab was triggered by a sledder in the alpine.

Snowpack Summary

15 to 40 cm of new snow sits over weak, faceted surfaces and may be slow to bond. At upper elevations, it has likely been redistributed by east wind.

Another layer of weak, faceted crystals and a crust are buried 20 to 50 cm deep.

The mid and lower snowpack is generally well-bonded and strong.

Weather Summary

An upslope effect associated with the passing front will bring snowfall to the eastern slopes tonight.

Sunday night

5 to 15 cm of snow. 30 to 40 km/h ridgetop wind switching from west to east. Treeline temperature -14 °C.

Monday

A mix of sun and cloud. 10 to 20 km/h northeast ridgetop wind. Treeline temperature -14 °C.

Tuesday

Mostly cloudy with scattered flurries bringing a trace of snow. 30 to 50 km/h south ridgetop wind. Treeline temperature -20 °C.

Wednesday

Mostly cloudy. 20 to 40 km/h south ridgetop wind. Treeline temperature -16 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Choose slopes that are well supported and have limited consequence.
  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • Potential for wide propagation exists, fresh slabs may rest on surface hoar, facets and/or crust.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

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.
