Regions

Waterton Lakes, Waterton.

With new snow, assess the surface problem before committing to significant avalanche terrain.

When the sun comes out, the likelihood of natural and human triggered avalanches will increase.

Confidence

Moderate

Avalanche Summary

No new avalanches observed the past few days.

Snowpack Summary

10-20 new storm snow sits on top of a melt-freeze crust and a slowly refreezing snowpack below that. The January drought layer lies 50 –130 cm deep, with snow depths at treeline averaging 130–200 cm.

Weather Summary

A pulse of snow is followed by a gradual warming trend. See the table below for a more detailed forecast.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Carefully evaluate big and steep terrain features before committing to them.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.

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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
