Regions

Waterton Lakes, Waterton.

Localized convective flurries could increase snowfall amounts in some parts of the park.

Pay attention to pockets of deeper windslab building on suncrust.

Confidence

Moderate

Avalanche Summary

No new avalanche observations this week.

Snowpack Summary

5-10 cm of dry snow overlies crust on solars at all elevations. Polar aspects still consist of dry snow above 1600 m. The January melt freeze crust is buried 60-100cm. Alpine and Treeline midpack is well settled and overlies basal facets and depth hoar. Below treeline, the Jan Crust overlies facets and depth hoar to ground.

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.
