Regions

South Columbia, Esplanade, Jordan, North Monashee, North Selkirk, West Purcell, Badshot-Battle, Central Selkirk, Goat, Gold, Retallack.

Dangerous avalanche conditions persist at all elevations! Large, persistent slab avalanches continue to occur daily.

Check out this conditions blog for more details.

Confidence

Moderate

  • We are uncertain about how quickly persistent slabs are gaining strength.

Avalanche Summary

Persistent slab avalanche activity has decreased slightly in recent days, but widespread avalanches up to size 4 have occurred at all elevations over the past week.

A size 2.5 avalanche, triggered by a tree bomb, failed on a February weak layer west of Revelstoke on Wednesday—an important reminder that these layers remain reactive despite the recent downward trend.

It remains uncertain whether new snow or wind transport will be enough to increase their reactivity again.

Snowpack Summary

While small amounts of snow continue to accumulate, the upper snowpack is settling and bonding under recent mild temperatures. Moist snow or a thin crust may exist at or just below the surface, particularly at lower elevations and on south-facing slopes.

Three problematic layers persist in the mid-snowpack. One or two surface hoar layers buried in February (depending on location) are found roughly 60 to 120 cm below the surface, and in some areas these sit on a thin crust.

A deeper, widespread layer buried in late January, made up of surface hoar, facets, and/or a crust, is roughly 100 to 180 cm deep. Surface hoar within this layer is most preserved and largest in sheltered terrain at treeline and below.

Terrain and Travel Advice

  • It's critical to stay disciplined and stick to gentle, low consequence terrain.
  • Be careful as you transition into wind-affected terrain.
  • If triggered, wind slabs may step down to deeper layers, causing larger avalanches.
  • Carefully manage your exposure to overhead hazards.

Problems

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.

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.
