Regions

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

Snowfall amounts across the region are variable, if the area you are travelling in has greater than 20 cm of snow, storm slabs are a concern.

Be willing to adjust plans to changing conditions.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.

Avalanche Summary

On Sunday, several size 1 to 1.5 dry loose avalanches were reported in the region. In nearby Waterton, storm slab avalanches were observed.

Snowpack Summary

Storm snow amounts are variable across the region with higher amounts forecasted to fall through Tuesday around Elkford. Up to 20 cm of snow will add to the 10 cm that accumulated on Monday, bringing storm slab totals to roughly 30 cm.

Storm slabs are building over old surfaces of:

  • wind-pressed snow in high elevation lees

  • crust on exposed windward features, south aspects and low elevations

  • soft, faceted snow, possibly topped with small surface hoar crystals in sheltered areas.

The remainder of the snowpack is well consolidated, containing a number of crusts which are not of concern at this time.

Weather Summary

Monday Night
Cloudy. 10 cm of snow. 20 km/h south ridgetop wind. Treeline temperature -5 °C.

Tuesday
Cloudy. 20 cm of snow. 20 km/h southwest ridgetop wind. Treeline temperature -8 °C.

Wednesday
Mix of sun and clouds. 10 km/h southeast ridgetop wind. Treeline temperature -14 °C.

Thursday
Mostly sunny. 10 km/h west ridgetop wind. Treeline temperature -15 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Watch for fresh storm slabs building throughout the day.
  • Storm slab size and sensitivity to triggering will likely increase through the day.

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.
