Regions

South Rockies, Bull, Crowsnest North, Crowsnest South, Elkford East, Elkford West.

Forecast problems and ratings reflect snowfall hotspots where up to 20 cm should create lively surface instabilities. Light new snow amounts shouldn't present much of a hazard elsewhere.

Confidence

Moderate

  • The snowpack structure is well understood.
  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

No new avalanches were reported in the region over the past several days However, observations are quite limited. Reactive surface instabilities will be in play on Monday, especially where snowfall is greatest.

If you are heading into the backcountry, please consider sharing conditions by posting a MIN.

Snowpack Summary

5-10 cm of new snow (Closer to 15 or 20 near Elkford/Sparwood) should accumulate through Monday morning. This will bury melt-freeze crust on solar aspects and otherwise add to 20 to 30 cm of recent snow, previously affected by extreme southwest winds, which either formed wind slabs on lee aspects (now a few days old) or stripped windward slopes to the crust below.

The recent snow sits on a thick crust and the snowpack below is moist to ground and well settled in most locations. Northerly aspects in the alpine may still be an exception.

The snowpack depth tapers rapidly at lower elevations.

Weather Summary

Sunday Night
Mostly cloudy with flurries bringing 5 to 10 cm of new snow, closer to 15 to 20 cm in parts of Elk Valley. 30 to 50 km/h west ridgetop wind, easing. Treeline temperature -7 °C.

Monday
A mix of sun and cloud with isolated flurries and a trace of new snow. 20 km/h west ridgetop wind. Treeline temperature -6 °C.

Tuesday
Sunny. 20 km/h south ridgetop wind, easing. Treeline temperature -3 °C with freezing level rising to 1700 m.

Wednesday
A mix of sun and cloud with isolated flurries. 20 km/h south ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Avoid steep, sun-exposed slopes when the air temperature is warm or when solar radiation is strong.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.
