Wind slabs may be reactive to riders especially where they are sitting on a crust or a weak layer.

Be careful with sluffing in steep terrain, especially above cliffs and terrain traps.

Summary

Confidence

Moderate

Avalanche Summary

No new avalanches were reported by Tuesday afternoon.

Pockets of wind slab may be reactive to rider triggers, especially on southerly facing slopes.

Snowpack Summary

New snow up to 20 cm with moderate to strong northeast winds may have formed fresh wind slabs. Dry loose sluffing from steep terrain features is likely as the new, low-density snow may show a poor bond to old snow surfaces including surface hoar, faceted snow and wind-pressed snow.

A crust up to 1900 m is found down 30-50 cm. In areas east of Quesnel and Williams Lake, reports say there is also a layer of surface hoar associated with the crust. This may also exist in sheltered alpine terrain features.

The midpack is reportedly well-settled and supportive.

Weather Summary

Tuesday Night

New snow 5-10 cm. Ridgetop wind 10-20 km/h from the west. Treeline temperatures near -15 C.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.

Problems

Wind Slabs

An icon showing Wind Slabs

Recent winds have built slabs at and below ridgetops in atypical areas. These slabs are likely to be more reactive where they overlie a weak layer of surface hoar and/or a crust.

Aspects: South East, South, South West, West.
