Regions

South Okanagan, Shuswap, North Okanagan.

Continuously verify conditions through the day.

Use your observations combined with smart travel habits to avoid places where isolated avalanche problems could exist in the terrain.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

On Wednesday, numerous small (size 1), wet loose avalanches were reported across the forecast area.

On Tuesday, sluffing and pinwheeling was reported with no new avalanches.

Snowpack Summary

The surface snow is saturated on all aspects and elevations. The recent snow along with the whole snowpack is settling rapidly and getting shallower.

A widespread crust buried earlier in March can be found down 70 cm. Layers of facets, crust, and surface hoar from February and January can be found just below this crust.

The remainder of the snowpack is well settled and strong.

Terrain and Travel Advice

  • Wind slabs are isolated, but may remain reactive.
  • Be aware of the potential for large avalanches due to buried weak layers.

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.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
