Regions

North Rockies, Sugarbowl, East Kakwa, Kakwa, McGregor, Pine Pass, Tumbler.

Small slabs may form in localized areas that receive more than 10 cm of new snow.

Confidence

Moderate

Avalanche Summary

A naturally triggered size 2 wet loose avalanche was reported on a southeast aspect on Monday.

NOTE: Observations in this region are currently very limited.

Snowpack Summary

A dusting of snow sits over a crust in most areas, except shady aspects in the high alpine where soft or wind affected dry snow may be found.

A persistent weak layer from early March, 40 to 80 cm deep, most likely exists as surface hoar on sheltered north and east aspects in the alpine. Its distribution is variable, and there have been no substantial reports of recent avalanches, but it should still be considered when evaluating slopes.

Weather Summary

Tuesday Night

Partly cloudy with isolated flurries, 0 to 3 cm of snow. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -8 °C. Freezing level valley bottom.

Wednesday

Mix of sun and cloud. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -4 °C. Freezing level 1300 m.

Thursday

Sunny. 5 to 10 km/h west ridgetop wind. Treeline temperature -3 °C. Freezing level 1400 m.

Friday

Sunny. 10 to 20 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2000 m.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

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.
