Storm slabs and a persistent weak layer are contributing to unstable snow conditions.

Use conservative route selection and resist venturing into complex terrain

Confidence

Moderate

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

Avalanche Summary

On Sunday, there were numerous reports of natural, skier-triggered and remote-triggered avalanches across the region in the size 1 to 2 range, with a few as large as 2.5. Some were storm slabs that stepped down to the persistent weak layer. Check out the photos below for some recent reports.

Storm slabs should slowly be gaining strength, but may remain reactive on Tuesday, with potential to step down to the persistent layer.

Snowpack Summary

15 to 40 cm of settling storm snow is covering a new layer of surface hoar and/or a melt-freeze crust in many areas. This may make storm slabs more reactive and resistant to bonding. An additional 5 to 10 cm is forecast overnight and through Tuesday. Southwesterly winds will likely continue building thicker slabs on lee slopes near ridgetops.

At lower elevations and on sunny the snow surface may be crusty.

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

Monday Night

Cloudy. 0 to 5 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Tuesday

Cloudy. 0 to 5 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Wednesday

Mix of sun and clouds. 0 to 5 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -7 °C.

Thursday

Mostly sunny. 40 km/h southwest ridgetop wind. Treeline temperature -5 °C.

Terrain and Travel Advice

  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
  • Start on smaller terrain features and gather information before committing to bigger terrain.
  • 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.
