Regions

Lizard-Flathead, South Rockies, Akamina, Flathead, Lizard, Bull, Crowsnest North, Crowsnest South, Elkford East, Elkford West.

Avalanche danger will rise with daytime warming and strong solar radiation.

Allow the new snow time to stabilize before committing to large, consequential terrain.

Confidence

Low

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanche activity has been reported since Monday, when warm temperatures and sun triggered wet loose avalanches.

Snowpack Summary

Recent snow at treeline and above has buried a mixture of moist snow surfaces and firm crusts. Lower elevations have seen a mix of rain and snow falling onto an already moist or isothermal snowpack.

A weak layer of facets above a hard crust may persist 50 to 70 cm deep. This layer hasn't produced avalanches in over a week.

Facets exist at the base of the snowpack in shallow areas.

Weather Summary

Thursday Night
Partly cloudy. 2 to 5 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -8 °C.

Friday
Mix of sun and clouds. 30 km/h northwest ridgetop wind. Treeline temperature -7 °C. Freezing level 1500 m.

Saturday
Mix of sun and clouds. 1 to 4 cm of snow. 10 km/h southwest ridgetop wind. Treeline temperature -5 °C. freezing level 1600 m.

Sunday
Mostly cloudy. 1 to 3 cm of snow. 10 km/h south ridgetop wind. Treeline temperature -3 °C. Freezing level 1900 m.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Investigate the bond of the recent snow before committing to your line.
  • Limit exposure to steep, sun exposed slopes, especially when the solar radiation is strong.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
