Natural avalanches are possible as more snow and strong winds continue to load the snowpack

Buried weak layers have produced recent, large avalanches

Confidence

Moderate

  • We are confident the likelihood of avalanches will increase with the forecast weather.
  • We are uncertain due to how buried persistent weak layers will react with the forecast weather.

Avalanche Summary

A widespread natural cycle to size 3 occurred recently, with most activity on north through east aspects at treeline and alpine elevations. Avalanches ran within the storm snow and on buried weak layers.

With further snowfall and strong winds expected, another natural cycle may occur.

Snowpack Summary

Another 50 cm of snow is possible by Monday afternoon, accompanied by strong to extreme southwest winds that will build deeper deposits on north- and east-facing terrain.

Storm snow continues to accumulate over heavily wind-affected surfaces, burying several weak layers of crust, surface hoar, and facets between 95 and 180 cm deep. These buried weaknesses are most concerning in sheltered treeline terrain.

Below, the remaining snowpack is generally well settled and bonded.

Weather Summary

Sunday Night
Cloudy. 10 to 25 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -3 °C.

Monday
Cloudy. 10 to 25 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -2 °C.

Tuesday
Mostly cloudy. 10 to 15 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Wednesday
Mostly cloudy. 10 to 20 mm of precipitation as snow or rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 0 °C.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Avalanches could start at higher elevations and travel into below treeline terrain.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.

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.
