Regions

South Coast Inland, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

Recent snow and wind have formed reactive slabs.

A buried weak layer persist and if triggered may result in a large to very large avalanche.

Review this video for persistent slab strategies.

Confidence

Moderate

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

Avalanche Summary

Throughout the past week, a large (size 2) natural storm slab was reported Thursday near Anderson Lake, with widespread cracking observed near Hurley Pass Wednesday. Earlier in the week, numerous small rider-triggered storm slabs were reported north of Pemberton. Explosive control produced cornice and wind slab avalanches, with one stepping down to a deeper weak layer.

Snowpack Summary

Moderate to strong southwest wind have formed deeper, and more reactive deposits in leeward terrain.

Expect to find, up to 35 to 70 cm of recent storm snow over a widespread, thick and hard crust below about 1800 m, and old wind-affected snow at upper elevations.

Two crusts, buried in early February and March are still a concern, particularly in the Hurley area and zones to the north. Expect to find them around 1-1.5 meters below the snow surface. Of the two, only the early February crust has been reported to have loose, sugary facets on top.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Be aware of the potential for large avalanches due to a buried crust.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

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.

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.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
