Regions

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

Wet loose avalanches may gain enough mass to trigger a weak layer in the upper snowpack.

Avoid sun-exposed slopes, especially if the snow surface is moist or wet.

Confidence

Moderate

  • We are confident about new snow amounts, but uncertain about whether slabs will form.

Avalanche Summary

Numerous natural and skier triggered dry loose avalanches were reported on Monday.

We expect this trend to continue through Tuesday when new snow sees sunny skies for the first time. A persistent weak layer down 70 cm may be triggered by wet loose avalanches, especially in areas where more than 20 cm of storm snow fell.

Snowpack Summary

Up to 30 cm of new snow has buried various surfaces depending on aspect and elevation: melt-freeze crust on solar aspects, and wind-affected at treeline and above.

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

Monday Night
Clear skies. 20 km/h west ridgetop wind. Treeline temperature -10 °C.

Tuesday
Mostly sunny. 20 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Wednesday
Mix of sun and clouds. 1 to 2 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Thursday
Mostly cloudy. 10 cm of snow. 30 km/h southeast ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • Loose avalanches may step down to deeper layers, resulting in larger avalanches.
  • 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

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.

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.
