Regions

Waterton Lakes, Waterton.

A lingering persistent slab problem remains on high, north‑facing terrain, though sensitivity is decreasing as warm temperatures affect the upper snowpack. Careful slope assessment is still essential before committing.

If sunshine develops, expect rapid warming on solar aspects, with wet loose avalanches becoming likely.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.

Avalanche Summary

No observations were taken over the holiday weekend.

Snowpack Summary

Surface snow is currently in a melt‑freeze cycle, becoming moist during the day and refreezing overnight, and rests on a thick crust. On north‑facing alpine slopes, facets persist on this crust with a slab above. The mid‑ and lower snowpack are well settled with no notable weak layers.

Terrain and Travel Advice

  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Be aware of the potential for large avalanches due to buried weak layers.

Problems

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.

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.
