Regions

South Okanagan, Shuswap, North Okanagan.

Strong southerly winds may be forming fresh reactive slabs on lee slopes.

Seek out sheltered terrain where the snow hasn't been affected by wind.

Confidence

Moderate

  • We are uncertain whether the wind will be enough to form new wind slabs.

Avalanche Summary

In the past few days, reported avalanche activity has been limited to small size 1 dry loose sluffs. With strong southerly ridgetop winds in the forecast, reactive new wind slabs may form and be triggerable on Sunday.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

Up to 5 cm of new snow may fall on Sunday. New wind effect will likely be building throughout the day if forecasted strong winds arrive. Unconsolidated soft snow will likely still exist on wind-sheltered slopes.

A couple of layers of surface hoar/facets or a crust are buried 20 to 45 cm deep, largely depending on aspect and elevation. These layers have been dormant, but they may become possible to trigger in isolated areas where enough of a slab forms overtop.

The remainder of the snowpack is well consolidated, containing several more crusts, none of which are considered a concern at this time.

Weather Summary

Sunday Night
Mostly cloudy. 1 to 5 cm of snow. 40 km/h south ridgetop wind. Treeline temperature -5 °C.

Monday
Cloudy. 2 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Tuesday
Mix of sun and clouds. 1 to 5 cm of snow. 30 km/h west ridgetop wind. Treeline temperature -6 °C.

Wednesday
Mix of sun and clouds. 1 to 4 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -5 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.

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.
