Regions

Lizard-Flathead, Akamina, Flathead, Lizard, Crowsnest South.

Large avalanches are expected in specific areas. Human-triggered avalanches are likely.

Avoid exposure to overhead hazards and open terrain where the wind has consolidated the new snow.

Confidence

Moderate

  • Uncertainty is due to how quickly the snowpack will recover and gain strength.

Avalanche Summary

No new avalanches reported.

As the storm tapers off Wednesday morning, human-triggered avalanches remain likely.

On Monday, explosives triggered storm slab avalanches to size 2. Additionally, two natural cornice failures triggered storm slab avalanches to size 2.5 on the slope below.

Snowpack Summary

Roughly 30 cm of storm snow is being redistributed by strong southwest winds. This overlies wind affected snow at upper elevations and settling snow at treeline. A spotty surface hoar layer can be found in sheltered terrain features.

A melt-freeze crust that formed Dec 24 can be found down 40 to 60 cm from the surface at elevations around 2000 m and below.

The mid and lower snowpack is characterized by multiple crusts, with moist snow persisting near the base in some areas.

Snow depths at treeline generally range from approximately 100 to 220 cm.

Weather Summary

Tuesday Night
Cloudy. 5 to 10 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Wednesday
Mostly cloudy. 1 to 3 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -8 °C.

Thursday
Mostly cloudy. 5 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -9 °C.

Friday
Mostly cloudy. 2 to 10 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -8 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Don't let storm day fever lure you into consequential 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.
