Regions

Waterton Lakes, Waterton.

10-15 cm of new snow is coming Tuesday night into Wednesday with moderate NW winds. Small reactive windslabs will be lurking on reverse-loaded features.

Confidence

Moderate

Avalanche Summary

No new avalanches have been observed as surface snow is refreezing.

Snowpack Summary

New snow is falling on top of a surface crust and a well-settled spring snowpack. Below treeline in the eastern areas of the park is generally below threshold for avalanches.

Weather Summary

Wed

Up to 15 cm by the end of today. Alpine high of -2°C. Wind N-NE increasing to 30-50 kph.

Tues

Scattered flurries with minimal accumulation. Alpine high of -2°C. Wind NE 10-20 kph.

Fri

Partly cloudy with isolated flurries. Alpine high of -2°C. Wind NE 20-30 kph.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Keep in mind the crust offers an excellent bed surface for avalanches.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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 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.
