Regions

Flathead, Lizard, Moyie, St. Mary.

Heightened avalanche conditions exist in specific terrain features where deeper pockets of dry snow sit over a weak layer.

Confidence

Moderate

  • We are confident that there are persistent slabs in the snowpack, but uncertain about how likely they are to trigger.

Avalanche Summary

Avalanche activity during the warm weather on Thursday and Friday was predominantly small loose wet, natural and skier controlled.

In the past week, human-triggered persistent slab avalanches have been reported size 1 to 1.5, failing on the late-January surface hoar/crust/facet layer outlined in the snowpack summary. Most of these avalanches occurred at treeline and above.

Snowpack Summary

A dusting of new snow falls over mostly crusty surfaces. The old surface may remain dry on the highest north aspects, and moist at low elevations.

10 to 20 cm of snow sits over the late-January weak layer. This layer consists of a melt-freeze crust of variable thickness, with a possibility of surface hoar on top and faceted snow above and/or below the crust. This layer is expected to become increasingly problematic as it gets buried deeper.

The mid and lower snowpack is generally well settled, with no significant concerns.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Closely monitor how the new snow is bonding to the crust.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.

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.
