Storm slabs overlying a persistent weak layer are creating dangerous avalanche conditions.

Careful snowpack evaluation and conservative terrain choices are essential right now.

Confidence

Moderate

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

Avalanche Summary

In the past few days, there have been numerous reports of natural, skier-triggered and remote-triggered avalanches across the region up to size 2.5. Some were storm slabs that stepped down to the late January persistent weak layer.

Storm slabs remain reactive, with the potential to step down to persistent layers buried deeper in the snowpack.

Snowpack Summary

20 to 50 cm of settling storm snow is covering a new layer of surface hoar and/or a melt-freeze crust that formed on February 7th in many areas.

The late January persistent weak layer, consisting of surface hoar/facets/crust, is buried 40 to 80 cm. It has surprised people with its reactivity over the past week, especially in sheltered treeline features.

The mid and lower snowpack is well settled with no layers of concern.

Weather Summary

Thursday
Sunny. 30 km/h west ridgetop wind. Treeline temperature -5 °C.

Friday
Mix of sun and clouds. 1 to 3 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Saturday
Mostly cloudy. 5 to 15 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -7 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
  • Be especially cautious as you transition into wind-affected terrain.

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.
